ABC warning on older model and shift slipping
 

My 99 s-class s320 has started showing warnings that says ACTIVE BODY CONTROL ABC VISIT WORKSHOP!

After parking the car the message despaired, weird its happens 3 times today right after Transmission slipping is to neutral in various speeds

Also most wired this car should not have ABC :confused:

Any advise is greatly appreciated

Your car doesn't have abc

has it rained recently ? Sounds more like some electronics problems , check under the windshield plastic grille to see if the reservoir is filled with water . Also check the tcu in the underhood electrical boxes to see if it has fluid or water on it

If there's no problems there , lastly check how old your battery is , could be errors from a weak battery

thanks Tusabes, the car is parked in my garage no rained since I bought it
the windshield plastic is clean
tcu - both of them is in great condition
battery was dead and replaced 2 weeks ago

ok, i found the tcm is leaking oil, i guess need to replace the transmission connector and oil pan gasket / plate.

It's always fluid /wAter damage when we see these kinds of errors

after the cleanup with cheap electric spay
i get ABS ESP ABC warnings, i think its dead!

Probably just need to reset all the settings


see the encyclopedia thread at the top of the forum for how to do all the resets
