If you've been following w215 forums for a while, you might remember my 2002 cl500 -> cl55 engine swap a few years back, or the first DIY ABC -> coilover suspension swap

for the suspension swap, I ordered the original Strutmasters kit. Non-adjustable coilover set. Not ABC, but not bad either

as most of you with ABC worries know, in order to fully complete the conversion from ABC suspension to a traditional setup, you must install a chip into the car to remove the ABC error light. the light DOES NOT go away by pressing the reset button. rendering your gas mileage, trip mileage, etc readings as useless.

I had a theory that simply removing the ABC control unit might get rid of the warning light, without buying the strutmasters unit. they used to sell it seperately for $200. kinda scammy

step 1 - open hood
step 2 - locate the ABC control unit in one of the waterproof electrical boxes by the windshield
step 3 - unplug unit and slide it out
step 4 - sell on ebay

Removing Fuses F9 and F46 will get rid of the RED ABC Warning with no side effects. The WHITE ABC warning remains, however, but it can be cleared with the Reset button.

Q: Will removing the ABC Control Unit get rid of the WHITE warning?

EDIT: no, it did not get rid of WHITE warning. In fact, it introduces ANOTHER white warning (ESP-Visit Shop). Note that the ABC controller was not confused with "ESP/ABS" controller - part numbers match the example below and looks identical. ESP/ABS was not touched at all, in fact. Perhaps there are car-to-car differences?
Thanks!

don't sell unless you want to end up with white warning light forever

ctravis595

I do not have any ESP warning lights, no ABC warning lights and my ESP functioned just as it should?

ctravis595

You're confusing the ABC controller with the ESP/ABS controller. I was one of the first ones to document trying to remove fuses f9 and f46. My new method gives no red error

here's an example of the module you guys are confusing with the ABC controller. It even says "ABS/ESP" directly on the module itself.

Linked below is the BODY CONTROL module I just sold on ebay

I do find it funny that we've all spent so much time trying to fiddle with fuses when the solution was very simple all along. Removing the ABC module took only a few seconds to do

well that"s great news then, let others try it too and post their experience

it would be interesting to hook up Xentry and read what that says
There is a option with ABC present or not present
that should be NOT PRESENT of course if you remove the module

ctravis595

is Xentry more in-depth than Star software? I remember visitng workshops and asking if they code out the ABC warnings but no luck. They used STAR

pmercury

xentry = das
I use the developper version like the factory. workshops use normal version

ctravis595

how have you liked the yellow racing setup so far? I'm glad there are more options than just the Strutmasters setup available finally! Your car looks like it has a great ride height

as long you add a sway bar front and if you can rear too it's ok
you get for what you paid for, ok coilovers, not premium
but far better then strutmasters as they have no settings
I found the springs are to soft and will be upgrading them + 8kg soon
I also just received the rear sway bar and will mount it before end of year

FYI, There are no Falsehoods, just conflicting experience.

It does not work on my 2003 CL 500. The ESP/ABS controller was not touched, and it was not confused. My ESP/ABS controller has a different part number than yours: mine is marked ESP-ABS-etc but number is 220 545 18 32 Q03.

With ABC module removed, still has White Warning and now ESP warning.

ctravis595

that's interesting. I think they changed A LOT of things on this car between 2002 to 2003. Not just the front bumper and AMG options, but seems to be quite a few other things that I'm noticing as well. This might be one of them

To me, now it DOES make sense that you might get an ESP error after removing the ABC module, as an ABC failure could indicate a very serious problem with your ride height, resulting in wheel rub/etc and unsafe driving conditions. Hence why it says ESP warning.

I also think my fuse diagrams are a bit different from you guys... in my attempts to remove some of the old ABC fuses like you guys have, maybe i took out one that helped my ABC module removal get rid of the error lights? It's still a tad weird to me that you guys would get ESP errors from an ABC module? But i can understand

Do you know if your ESP still functions properly without the ABC module?

ctravis595

or, maybe try to replace your ABC fuses, and THEN try removing the ABC module. Perhaps one of the fuses you removed previously have changed the outcome of removing the ABC module? also i would make sure to disconnect the battery for a while to reset everything also

it's hard for me to guarantee this will work if many things have already been altered along the way

ctravis595

You guys were correct, after a battery reset today, I am now getting a new ESP and ABC White warning lamp. Might have to reconsider selling the abc module now

edit: this was because I hadn't reset the steering angle sensor yet. after resetting the battery, it's required to turn the wheel full left and full right to get rid of ABS and esp error

ctravis595

pmercury, with developer mode in STAR, do you think we can disable the white ABC warning lamp? what about with removing the ABC module, or the fuses you mentioned, is there a way to disable the lamp?

ctravis595

Forgot to update this thread

last I recall, I have removed both abc computer and abc fuses

no red warning light. There is still a white warning. I also still have esp functions. I’ll double check sometime soon that I have everything correct

recently tried to code out abc in star, but it only gives you an option to switch to airmatic , which we know would give an airmatic message code instead

smartadze- for what it’s worth, my 2002 W215 seems to have 2003 software as I am able to access dyno mode and such that was only on 2003+ models

edit: removed abc computer and fuses. I still have full esp / abs / bas functionality and only one abc white error warning

BoxxMann

Works like a champ! I just get a white error and that's it!

trabots

Folks, I have a rhd SL55 and I have taken both covers off each side under the dash and cannot see anything that looks like the ABC controller under there. Please help if you can. Cheers.

have a 01 s600 with conversion kit. Did anyone figure out how to eliminate red AND white abc lights?

BoxxMann

I have a 2002 CL500 with Yellowspeed Coils with W220 power steering pump, and removing the ABC control module is all that needs to be done to clear the RED WARNING. I still get the white ABC on startup, but that clears off a press of the R button. The module is located in the engine compartment fuse box, driver side (US)

@m3j0n it's unlikely there is a solution to clear the white warning. Good luck doing that.

Ha...I see I've already posted here...a year later lolo!

superfast

BoxxMann- Off subject. How long have you been driving w/ the Yellowspeed coilovers? What are your final settings of the front & rear & are you happy w/ the conversion?

I have this warning light project done, on some CL's I removed all light with programming
if you have a running computer and a C4 or C3 I can try

BoxxMann

I have the fronts and backs on the "middle" setting, meaning in the middle of the adjustment rang. I think the fronts are more firm. My advice: Do NOT waste good money on the ABC. Pull it out, put in coils, swap out the pump and enjoy. The ride is like a conventional sprung suspension, of course, but the peace of mind is worth it. While my CL is not a daily driver, I know I never have to fret over the ABC any time I do drive it. And I can live with clearing the white warning on startup...it's no big deal at all and nothing but a trivial inconvenience at the worst.
