Is the truck still driveable?
Do a search on the board - I'm sure you'll find the answer.

I had the same problem last year after I had washed the car. One of the sensors in the rear offside wheel had failed. Was a £90 ( $180 ) fix at the dealer.

does the light go off after you drive the car? I have an E320 older model (2000) and it used to turn on. My brother's CLK320(99) the lights used to come on too randomly.

My ML500 the light also comes on sometimes.

All of them you just turn off the car and later it is ok.

FYI, i used to even get so annoyed at the lighting BAS/ETS light that i used to shift the car to neutral on the freeway when nobody's around and on a straight, turn of the car and turn it on, it will go away.

Do not try this at home

Brake light switch is the most common cause for this problem. If its not that spend the money to have it diagnosed by the dealer. In any case, get it fixed ASAP as these are important safety systems and they are disabled when the lights are on.

There is too many parts that will cause the light to go on.
ABS unit > lateral acceleration sensor > Yaw Sensor > brake switch > Steering angle sensor, Wheel speed sensor.

DAS computer will see what sensor has failed. My dealer charged 1 hr for diagnoses which is $125 an hr.
