ASR & ABS come and go at same time
 

96 SL500: the ASR & ABS lights come on after a few minutes of running the engine cold and hot. If you turn off the car and turn it on twice it goes away. on the second restart, Both lights come on again together! The car has no driveability issues runs great. I have seen similar post on earlier models with the bad harness issues,but this was suposedly corrected with this 96 model. I have seen posts about the ETA,but this car runs and drives great no limp home mode issues................Puzzled:confused::confused:

asr warning
 

You system requires 13.8 volts at start, anything lower will trigger the warning lights your battery most likely is the culprit, it has enough power to start the engine so it is not normally a suspect, your lights will reset after your alternator brings the voltage up.
my 2 cents

Voltage good
 

Hi,Thanx for the suggestion checked voltage it is good around 14v batt cks good.even when lights come on voltage is good. May have found the problem unless it is a coincidence when I shake the wires going to the ETA the lights comes on??????????????:confused:

I bet its a brake light switch, even with working brake lights this $160 part failed on my ML430 and crapped out both systems.

I too vote for the brake light switch (above the gas pedal).

$160!! I replaced mine and the one on my friend's ML320 for $15 each.

John, check the ETA wiring to see if it has the brittle insulation problem.

Insulation 119 engine
 

Cut open the eng harnesses around the ETA and the MAF wiring looks beautiful brand new no cracks. I have heard about these brake light switches. It sounds cheaper than the ETA also seen ETA on Ebay for about $300.00,should be easier to change also. Maybe a little contact cleaner on the switch internals may bring the brake light sw back to life...Thanx John:cool:

Replaced the EA (electronic actuator) today. problem solved!:D
Got one off a 97 E class with the 119 eng, best $200.00 bucks I ever spent!
sometimes ebay is ok. thanx guys John....................................
