Tools:

E6 socket

Applicable Models:

Mercedes-Benz W203 (2001-07)

Parts Required:

New ABS Control Module

Hot Tip:

Clean the contacts

Performance Gain:

Better braking

Complementary Modification:

Bleed the brakes

Without a doubt, your brakes are the most important systems on the car. There is an ABS control module that reads the information from various sensors on the vehicle and controls brake modulation. If this control module goes bad it can cause all kinds of problems with your braking system.

Replacing the ABS control module very easy, which is nice, because it is very expensive.

Begin by disconnecting the ground strap from the battery and making sure it can not make contact again while you are working.

The control module is located on the front of the ABS unit. The control unit has the two lines in from the master cylinder and the four lines going out to the wheels attached to the top of it.

Located on the left side of the unit is the main brake wiring harness. It is easier to remove this once the module is off the unit.

Using an E6 reverse Torx remove the four screws securing the module to the front of the unit. Pull the module straight back and off the unit. With the module off, unclip the harness and rotate the cover up. This will release the harness from the module.

Before installing the new module make sure you clean the contact surfaces on the control unit and check for corrosion on the harness.

Installation is the reverse of removal

Robert Comments: My ASR/BAS light was on when I push brake pedal and asr doesnt work-brake switch was bad. I change it and now ASR works but when I push brake pedal fast or deep BAS/ASR light comes again but ASR works... Abs works too. Turn off the engine and turn it on and light comes off till I pull brake pedal fast again... Where could be the problem?

Tex Comments: I have a 2002 C240 I get abs/esp readings when it starts -the gear shift is stuck in Park-but can be moved using the override button-willreplacing the front abs control module shown above correct this? I removed the under dash panel & there is no brake light switch that I can see. Thanks
October 26, 2016
  Followup from the Pelican Staff: You will need to see what fault code is stored before replacing any parts. i would start there. - Nick at Pelican Parts  
lamin Comments: Hi got I c270 cdi benz diesel which is stuck in park gear and wen i try to start it. It just cranks pls help.
October 10, 2016
  Followup from the Pelican Staff: Are there any fault codes stored? - Nick at Pelican Parts  
timbo 1989 Comments: intermitten brake issues my brakes locked up agin pedal is hard as a rock last time it did this it was only ther rear now all four have locked aginn pedal also is very hard agin I don't know what to do I had to hit the breaks hard today and I felt a grinding snd slipping feeling in the break pedal tires didn't lock up or anything but itfely it in the pedal almost like two pieces or wet rubber rubing each other I really need to diagnos this issue I love this car and it is very reliable except the brake issue
September 21, 2016
  Followup from the Pelican Staff: Could be a faulty master cylinder, brake booster or abs unit. You will have to isolate the pressure loss. - Nick at Pelican Parts  
mudathir Comments: I have E 240 model 2003 when normal driving some time coming message on dash board brake defective stop vehicle at this time reduce the speed , when i make switch of and restart message gone out but some time coming again when i checked by computer fault cod : N47-5 &a7/3
so i need your advise as soon as you can
August 5, 2016
  Followup from the Pelican Staff: Those fault codes don't come up for me. Do you have the description? What module were the codes scanned from? - Nick at Pelican Parts  
Akzee Comments: It's so random that even when i dropped the car at the workshop for over a week, it didn't happen. I'm the only person who has experienced it happening, and I begin to wonder whether the manner with which I step on the brakes matter. Initially I thought it was a mechanical problem but when the BAS started coming on, occasionally too, I started thinking more of a sensor problem. Like a gradual/partial brake failure kind of thing. Sorry I'm very green when it comes to car stuff. It's really scary when it happens though I'm beginning to learn to anticipate it everytime I step on the brake, whcih is really quite tiring and it doesn't help anything anyways.
July 8, 2016
  Followup from the Pelican Staff: The hydraulic system will not quit when a sensor does. There is likely a pressure drop somewhere.- Nick at Pelican Parts  
Akzee Comments: Hi. I have a 2002 c320. Intermittently when i apply the brakes, the brake pedal momentarily loses its grip and goes soft all the way down before gripping again. It's usually a split second thing but it lurches the car forward inertia. And I've changed the brake pads. Occasionally when this happens the BAS comes on. More recently, a scan highlighted the membrane travel sensor. Can this be the only problem? Nobody seem to know what the problem is.
July 8, 2016
  Followup from the Pelican Staff: Sounds like the brake master cylinder is failing. Only way to confirm is to check master cylinder pressure. - Nick at Pelican Parts  
Sasha Comments: Have 2001 C320 Car loses power and the ESP, BAS, ABS light comes on. Can I replace the ABS module with a used one or I need to purchase a new one from the dealer?
June 10, 2016
  Followup from the Pelican Staff: You should be able to, it will need to be programmed. - Nick at Pelican Parts  
J Comments: Thanks Nick,I actually unplugged the yaw rate sensor under console and so far no other issues with brakes locking up, but the bas lights stays lit
June 10, 2016
  Followup from the Pelican Staff: Thanks for the note. - Nick at Pelican Parts  
J Comments: I have a 2001 slk230, bas/esp light on at times,recently while driving feels like right rear tire locks up and caution triangle comes on,very scary what could be my issue,car only has 80k miles
June 6, 2016
  Followup from the Pelican Staff: COuld be a faulty wheel speed sensor or brake caliper. I would start by checking the vehicle for fault codes. - Nick at Pelican Parts  
Kestinio Comments: Hi i have a w203 2.7cdi 2001, and i have a problem with ESP. Sometimes it starts to brake by itself with the front right wheel and acceleration disapears so about 2-3 times usualy after acceleration from parking, it makes such like abs braking sounds,when the speed is faster that braking is softer, and at the same time flashes ESP visit workshop with Atention triangle.i had this problem last summer, at wintter time it was gone, now it hapened again, any ideas? please help :
May 18, 2016
  Followup from the Pelican Staff: I would stop driving the vehicle until you can have the system repaired. Start by checking the vehicle for fault codes, that will point you toward the problem. It can be a faulty caliper or an issue with ABS system.
- Nick at Pelican Parts
 
Benzo Joe Comments: I own a 2005 e320 and recently got a red light message on the panel stating that the "brake power is low,take to shop". The Mechanic told me it was the ABS sys. Can I continue to drive the car or is it possible for the brakes to go out?
May 14, 2016
  Followup from the Pelican Staff: No. Not if you have reduced braking. That is unsafe. - Nick at Pelican Parts  
pejewins Comments: It's a 2000 with around 200k, it generally intermittently grabs the left front wheel at low speeds locking it up sometimes without applying any pressure to the brakes, sometimes at higher speeds, it occasionally locks up the lfront right wheel. If I were guessing a ratio maybe 4 to 1. Left front abs locks up versus right front with ABS disarmed it never locks up on either. I have looked high and low for a wiring diagram on how to remove that chime altogether. Thank u so much for any info u may have to help. Dealing with this issue for nearly a year now. God bless you.
February 27, 2016
  Followup from the Pelican Staff: My notes remain the same: There could be a faulty sensor or tone ring. MOnitor wheel speed data when the problem is present. Look for the wheel that doesn't match the others. - Nick at Pelican Parts  
pejewins Comments: Replaced abs control module on my ML320, however at low speeds, intermittently the abs continues to activate, As if locking up the brakes. I disabled abs altogether but can't figure out how to rid myself of the annoying chime it feels safer with abs off than driving it while abs Vick on for no reason. There was no corossion behind abs module. Is there any way at all to make the little chime stop beeping?

Jeffry Comments: Hi,I have 2004 MB e320. The break lights is on on totally red.i have changed pads and shoes and bleeded. My mechanic said it is abs pump.can i rebuilt it? Is there a part kit i can buy?
February 15, 2016
  Followup from the Pelican Staff: There is a part available. Give our parts specialists a call at 1-888-280-7799. They can figure out what part or repair kit you need.
- Nick at Pelican Parts
 
elvis Comments: My ML320 has reported error code P0600. i understand this indicates power train control module problems or CAN bus communication problem. How do i solve these on my own?
February 15, 2016
  Followup from the Pelican Staff: COmmon issues are K40 relay, control module failure and bus system short. To diagnose, you will need a scan tool that can check every control module to see which one is on or offline when the fault is present. - Nick at Pelican Parts  
elvis Comments: i have a 2000 ml320. problem is, the beeper comes on after some minutes of driving or running the engine with the ets, abs, brake pad and brake lights coming on. moreso, the limp mode is activated and car drags when accelerating after decelerating.
i just changed the front right speed sensor thinking this was the problem.
what could be wrong?
February 4, 2016
  Followup from the Pelican Staff: Almost anything could be the cause. I would start by checking the vehicle for fault codes. If multiple systems are not working properly, fault codes will be set. This will be your best bet when diagnosing.
- Nick at Pelican Parts
 
otas Comments: Hi, I have a benz GL 450 4matic. A message is displayed in the instrument cluster "ABS, ESP inoperative, consult the operators manual". The wheel locks sometimes but when I replaced all the four tyres ABS sensors with new ones, drove for a short distance and the light went off. However i remembered I did not clean the Hub with a choke cleaner, so i removed all four sensors again and spray-clean the wheel hubs. But after reinserting it again the light came on again. Please what should i do to erase the fault? my system is OBD II but its not even seeing the ABS control unit.
February 2, 2016
  Followup from the Pelican Staff: You'll need to figure out why the light is ON. I would start by checking the vehicle for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.

Bayla Comments: I have a 1999 MB CLK 320 convertible. BAS and ASR lights are coming on and off intermittently. MB says the ASR module may be bad but they are not sure. If that doesn't work, then ASR plus the "pump." MB says car is working perfectly-including ASR and BAS and that it is safe. They suggest replacing ASR module first, then the "pump." If that doesn't work, they would look for wiring problems. They say both ARS and pump are linked together as a programmed unit. Am I better off replacing both at once? Can I buy them as a unit? I understand I'll have to have them programmed.
January 21, 2016
  Followup from the Pelican Staff: Just get them both replaced, then programmed. Way easier than going in there twice, labor should be less if doing both then doing them separately. Give our parts specialists a call at 1-888-280-7799. They can figure out what part or repair kit you need.

Florida Bass Comments: I have a 2003 ML320, my brake lights are not coming on when I press the peddle. I checked the fuse all is good. I think its the brake switch. I looked under the dash and can't seem to locate the switch, can anyone assist Thank you
December 16, 2015
  Followup from the Pelican Staff: It should be mounted directly behind the brake pedal lever. Under the instrument panel. - Nick at Pelican Parts  
BJ Comments: I have a 2001 SLK 320. The ABS light come on frequently and now car breaks sometimes at highway speedsdangerous. Can it simply be disconnected electrically and continue to drive without ABS protection?
November 22, 2015
  Followup from the Pelican Staff: Usually when the ABS light is ON, it is disabled. You may have am ore serious issue. I would have the vehicle inspected immediately and stop driving it until you do. - Nick at Pelican Parts  
GMO Comments: If after replacing the ABS unit, with a different unit and all lights on dash are not lit now, does it still need to be reprogrammed at dealer?
November 21, 2015
  Followup from the Pelican Staff: Yes, it will need programming. - Nick at Pelican Parts  
GMO Comments: I got it. I did not slide it all the way up. Was stuck about 1/2 way
November 7, 2015
  Followup from the Pelican Staff: Pull the connector away as you slide the lever. - Nick at Pelican Parts  
GMO Comments: Can't figure out how to detach wire harness on 2002 ml320 abs control module I can slide it up, but, not sure what to do after that.
November 7, 2015
  Followup from the Pelican Staff: Slide the lock up as you pull the connector away. - Nick at Pelican Parts  
Lady mechanic Comments: I got the old module off, but I am having difficulty detaching the wiring harness. Should I pull up, press something or what. Please advise.
October 29, 2015
  Followup from the Pelican Staff: The connector has lever, open it to disconnect it.- Nick at Pelican Parts  
SamKenobi Comments: *Correction:
Intermittently i had to step on the brake pedal DEEPER THAN USUAL for the car to respond and decelerate
October 27, 2015
  Followup from the Pelican Staff: Got it. thanks. - Nick at Pelican Parts  
SamKenobi Comments: Hi, im driving a w203. I've been having problems with my braking system. Intermittently i had to step on the brake pedal for the car to respond and decelerate. Is this because of the ABS module or the pressure sensor? Though there is no alarm trigerred on the display
October 27, 2015
  Followup from the Pelican Staff: Could be a failing master cylinder. Check if there is a sign of leaking.

With the engine off, pump the brake pedal until hard. hen press and hold. If it sinks to floor, the brake master is likely the problem. - Nick at Pelican Parts
 
venturi476 Comments: Hi am referring to replacing the esp bas module as described my car is slk r170 2001 200 manual krompressor. An autel au702 reader said the module is defective. Any advice much appreciated.
October 25, 2015
  Followup from the Pelican Staff: Got it, you will need to code / program using a Mercedes-benz scan tool. - Nick at Pelican Parts  
Venturi476 Comments: Hi
I found this tutorial very helpful. However, before starting the job, I was wondering if any diagnostic adjustment reset is required ir alternatively, will it reset itself once the battery is connected and steering is operated lock to lock on my slk r170. Thx.
October 25, 2015
  Followup from the Pelican Staff: The module will require programming once replaced. - Nick at Pelican Parts  
brg68b Comments: My 2005 C2330K has a abs and ets light on. When I start the car it runs fine, when I start to drive it goes into limp mode. The car is a 6 spd manual so it moves and it kicks out of limp mode any where from 2 seconds to about two minutes.Codes came up C1102 and C1114. I can find no info on these items in my searches. I did change the left rear wheel sensor with the C1102 code - but am lost where to look. Any thoughts appreciated.
Thx
September 13, 2015
  Followup from the Pelican Staff: I think they are speed sensor codes. Check the input and output speed sensors for the transmission. - Nick at Pelican Parts  
roy7423 Comments: i have a cl203, 2007. no warning lights but abs is pumping when braking at all speeds. vibration through the pedal and at speeds in excess of 70 mph feels like car is about to disintegrate. has had new discs/pads etc but made no difference
September 7, 2015
  Followup from the Pelican Staff: If the pump is running, either there is a sensor issue in the ABS unit or the pressure is bleeding off causing the pump to run. - Nick at Pelican Parts  
Mercedes lover Comments: I have a 2001 C320 with 174,000 miles. When driving the car will lose power and the ESP, BAS, and ABS light comes on. The car never regains power until I stop and I turn the car off and restart it again. I was misdiagnosis twice by the dealership and by the three time I was told that I needed to replace the ESP control module. I need help with this problem please.
September 1, 2015
  Followup from the Pelican Staff: What fault codes are stored? - Nick at Pelican Parts  
DevilDawg Comments: My 2000 ML320 BAS/ESP ABS lights are on. Can I just purchase a used one and install it or does it require programming?
August 31, 2015
  Followup from the Pelican Staff: You will have to program it. - Nick at Pelican Parts  
Ash Comments: "ABS,ESP and Brake-see workshop" warnings show in the dash and te ABS light alone is lit. Mechanic pulled codes and checked ABS system. Rear right ABS tone ring and ABS sensor faulting. recommends replacement but no guarantee ABS will work if module is also faulty. Does that sound right? Can i forfeit fixing ABS and just depend on my primary Brakes for highway driving. Cost of fixing tone ring, sensor and module?
August 17, 2015
  Followup from the Pelican Staff: The tone ring is easy to inspect, check for rust around it, pushing it and causing it to crack.

Sensor can also be testes for signal output into the module.

I would get a second opinion with a more confident diagnosis. You can drive the vehicle with the ABS not working, but you will not have anti-lock or traction control, only normal brakes. - Nick at Pelican Parts
 
eduarelflaco Comments: I have an SLK320 year 2004, I have a light on in my dash of ABS, BAS and the ABS Pump always on with the switch turn off and out key, always pump on and discharge the battery
August 13, 2015
  Followup from the Pelican Staff: Sounds like a fault with the control module. - Nick at Pelican Parts  
Jay Comments: I have a 2000 E320 with ABS/BAS WARNING LIGHTS. I had an independent service center change the brake light switch but did not solve the problems problem. He scanned the car and received the code that the BAS control module is faulty. Is this something I could tackle DIY.
August 8, 2015
  Followup from the Pelican Staff: You can replace the module, but will need to have it programmed when done. - Nick at Pelican Parts  
Crane Comments: I have a 2000 C230k and the BAS/ESP light comes on every time it is driven. Sometimes the car accelerates and then kind of jerks and corrects itself and then BAS light illuminates. . I was told by the dealer that I need a new control module and the part and labor costs more than value of car. Can a used part be used? How can module be paired with my car?
July 13, 2015
  Followup from the Pelican Staff: I don't think a used one will work. Give our parts specialists a call at 1-888-280-7799. They can figure out what part or repair kit you need.
- Nick at Pelican Parts
 
CSDR Comments: I just had the brakes and rotors replaced on my 2003 c320. The car has been driving fine until I took it for an oil change today and now my hood latch warning light is on and all four brakes are locked up. Any thoughts on whether this is due to a bad brake replacement or if it's related to the hood latch sensor?
May 4, 2015
  Followup from the Pelican Staff: Likely due to the hood latch sensor. See if you can test it, check if it reads open when the latch is closed. - Nick at Pelican Parts  
Confused Comments: 2006 e320cdi. Abs/ESP warning on digital display and warning light in abs. Is this the control module I need to replace or the abs module?
April 29, 2015
  Followup from the Pelican Staff: Before replacing anything, check the ABS module for fault codes. The fault code will direct you to problem area. - Nick at Pelican Parts  
timbo 1989 Comments: thats what i was thinking but i have no lights except check engine but thats for bank 2 flow and o2 censor but no abs lightts or anything of that nature thats y i am stumped because all four tires locked up but i get no lights
April 21, 2015
  Followup from the Pelican Staff: The pump is always running, there is a fault. May not be a light is the control module thinks it is doing the right thing. - Nick at Pelican Parts  
timbo 1989 Comments: yes all four tires will lock up and there is no power to my brakes the abs pump seems to be running to lines always vibrate when im under the hood and motor is on
April 20, 2015
  Followup from the Pelican Staff: If the ABS pump is always on, I would start by checking the vehicle for fault codes. There may be an electronic fault in the abs system, causing the brake pedal issue. The fault code will direct you to the area of the problem. - Nick at Pelican Parts  
timbo 1989 Comments: 1998 e320 v6 why are my brakes locking up ?? it just happened to me today and I haven't had a problem before now ??
April 15, 2015
  Followup from the Pelican Staff: Are any warning lights ON? Are all four wheels locking up? - Nick at Pelican Parts  
jerseyjoe Comments: I have a 2004 ML350 with all the ABS lights on and alarm. I just changed the battery because it was dropping below 10 volts while cranking. I will measure the battery voltage tonight. This is what I pulled off the scanner this morning when I downloaded to my computer. Could it be possible it is just the Alternator over charging? What is the max charging/ battery voltage?
Present C1012
1.control unit N45-5 ESP and BAS control Module is faulty
2. Control unit N47-5 ESP and BAS control module is defective.
3. Over-voltage during operation
4. Over-voltage #8 during operation
5. Terminal 87 has overvoltage
6. Terminal 87 overvoltage
7. Overvoltage at terminal 87
8. Overvoltage at terminal 87 fault in operation
9. Fault in operation
March 5, 2015
  Followup from the Pelican Staff: Perform a charging system test, should be around 14.6 volts running, and drop slightly when under a load. The real test for charging system is current, as the system is loaded, current will rise. Use a charging system tester with an inductance clamp to measure this. - Nick at Pelican Parts  
Tim Comments: I've a 2005 ML350 that has started producing a repetitive clunk while braking moderately hard. It is generally about 3 clunks, within about one second, and does not happen while braking lightly. I think it is coming from the Front, Driver's side. FYI, I recently replaced the front rotors, as the old ones had non-uniform thickness are were causing some judder while braking. This may have masked the pronounced clunking I'm now hearing.

Anyway, ABS malfunction is my first guess, based on the "periodicity" of the sound, but I'd much appreciate professional insight and a DIY troubleshooting plan. I will jack it up soon and double-check for any loose joints, bearings, etc. Is there a OBDII scan tool that would show correlated ABS action if it is occurring?
January 8, 2015
  Followup from the Pelican Staff: Inspect the front end. Sounds like you have a faulty suspension component. - Nick at Pelican Parts  
Big Qua Comments: I have a 1995 E320 and the ASR light comes on set the car on a Limp Mode. Will changing the ABS module fix this problem? My mechanic says I can disconnect the ABS as a temporary fix. What do you think?
September 28, 2014
  Followup from the Pelican Staff: I can't make a guess at this one. I would start by checking the vehicle for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing. - Nick at Pelican Parts  
911ST Comments: Sorry, would need a module for a 2000 ML 320.

Thanks.
June 22, 2014
  Followup from the Pelican Staff: No problem, got it. Give our parts specialists a call at 1-888-280-7799. They can help you find the right part.

911ST Comments: Can the modules be bought as a stand alone? Where?
June 22, 2014
  Followup from the Pelican Staff: Yes. Give our parts specialists a call at 1-888-280-7799. They can help you find the right part.

  Followup from the Pelican Staff: You are going to have to monitor wheel speed using a scan tool and or labscope to determine which wheel has the issue. Once you identify the problem wheel, check the sensor and sensor air gap. - Nick at Pelican Parts  
Max Comments: I own a 2004 Mercedes C230k, 115,000 miles. Having starting issues. At first, it would eventually start after I removed the key and tried several times. Now it won't start at all. It just makes a whirring sound. All the electrical a work fine. I replace the battery still no good. I saw online that it might be the engine ground strap. I've never heard of that and don't know where it is. Any suggestions??? Thanks!
November 5, 2013
  Followup from the Pelican Staff: Sounds like the solenoid on you starter has gone bad. Try changing the starter. - Kerry at Pelican Parts  
andy Comments: I have a 2004 mercedes e320 change the abs module and brakes still lock up on reverse and drive any theory text me 9492749525thanks
September 25, 2013
  Followup from the Pelican Staff: You may have one or more bad wheel speed sensors. You should check for diagnostic trouble codes in the system before replacing any parts. The module also needs to be coded to the car. - Kerry at Pelican Parts  
mespe Comments: If this control module goes bad it can cause all kinds of problems with your braking system.

All kinds of problems? Please be specific. can it cause excessive pedal travel? Can it cause a caliper to lock up? Can it cause the flexible brake line to rot? joking
Just thought I'd try to help out,,,
September 18, 2013
  Followup from the Pelican Staff: A bad control module can cause all those problems except the rotting brake lines. I assume we're talking about the ABS ASR control moduel. - Kerry at Pelican Parts
