Yet another ABS, ESP light ..Help? Gilly..Anyone?
 

Hello:

I own a 1997 S600, and i have the ABS, ESP light on.

I had replaced my battery with a new one, and i could swear the esp, abs came on after that, but it could be something else.

I did a search on here, and i tried the steering wheel trick, back and forth, but it didnt solve it.

Someone suggested that it could be a brake switch problem, but my brake function properly and lights come on. Could it be the brake switch, if the brake lights are functioning?

Now another thing of course, that it could be the battery. But the battery is brand new. I had it tested and it was putting out 12 or so, but at crank it was putting about 10.5. I heard before that if goes 10 or under that might activate those lights?

Another thing, i took it to my mechanic, and he ran the scanner on it, and he scanned everything, but he told me that he couldnt communicate with the abs, esp module to get a code or anything.

any suggestions on what is causing the lights to come on...i will be appreciat it.

One last thing since we are talking about esp, my suspension on the s600 are hydrophmautic with ads i think. I heard that sometimes the ads or suspension somehow might go in default when changing a battery and not function properly. Can anyone give me some insights on that too.


Thanks guys

I know that this is posted all of the time BUT, since that system is computer controlled...have that system scanned for codes. I wouldn't even try working on that car for that problem with out connecting a scanner! NOT ODB2 but a scanner to read codes from the traction system.

the brake light switch has extra circuits in it for the computers just because the brake lights work doesn't mean it's good.less than $20 and a common problem.

I had the same problem recently with my 97 E420 and the brake switch was the culprit. For a part that's <$20 that's where I'd start.

fuse
 

Hi You might want to remove the cover over the modules and check the fuses that are inserted on top.The cover is held in by a few 3 or 4 mm allen bolts,its located in frt of the pass side fire wall.Good luck.Joeym
