Re: 1996 mercedes E-CLASS ABS LIGHTS ON AS I START TO...
You should be able to pulse the pump in actuator tests you can test the signal at the same time.your cruise wont work if the abs isnt working it takes the readings from the wheels,check your power and earths at the pump.

Brake light switch problem may cause the ESP / BAS lights to illuminate.
Common symptoms of a bad
Mercedes brake light switch.
Car stuck in Park.
ABS ESP ETS lights come on.
Can not move the shifter from Park to Drive.
Brakes Defective Warning on Instrument Cluster
Car won't shift gears. Stuck in 2nd gear, limp mode.
Brake lights don't work. (Brake light switch can still be defective even if the brake lights work. Checking the brake light operation is not a good test.)
ESP, BAS, ABS lights turn on. Car won't shift properly. Stuck in gear.
TEST: To test your new brake light switch: Turn you car off to reset the ABS light. apply the parking brake. and start the car in neutral or park without using the brake. if the problem is the brake light switch... the light will only come on when you press the brake pedal.
If you replaced the brake light switch and the light is still on you should check a few other things such as:
Fuses and Relays
ABS wheel speed sensor
Brake Fluid Level
Get an advanced scanner to read trouble codes.
NOTE: ** You may need a MBZ scan tool to reset the error code which was stored in the ECU because of the bad brake light switch.
The ASR and ABS are voltage sensitive, so each time you disconnect them from power, they will reset. To cancel the ASR light, start engine then turn steering wheel full lock to right, then lock to left...ASR should extinguish. ABS light should then go out once you drive above 8 mph for 100yards or so. Until you can have the climate control looked at by a professional, I would locate and remove the fuse for it when you park up. Much better than disconnecting battery.
every time that light stays on it means that the ABS sistem is disabled...if theres a problem with the sistem it disables itself for safety...so you need to take the car to have it checked and figure out what is wrong, that light is there to let you know theres a problem and now the sistem is disabled so u need to have it scanned and diagnosed. hope this helps
Most likely cause is the 'stop lamp switch'
It is a electric switch located on the brake pedal inside the car, about half way up on the brake pedal.
Pretty cheap too, I think the switch is only like $25 bucks.
2 connectors on the switch and then it turns out.
hope that helps
