I replaced the brake stop switch according to 1sloturtle's directions and it still does all of the malfunctions. I am going to leave the battery disconnected overnight to see if that works.

I am an electronics technician by trade. What makes sense to me (with no schematics or wiring diagrams to work from), is when I shorted the brake light voltage, it damaged whatever module provides the voltage to the brake lights. It obviously has inputs from the anti lock braking circuitry since it is supposed to supress the brake lights in an anti lock for stability condition.

Does anyone have a wiring diagram for this vehicle, or a similar model in 98? Or perhaps can tell me where the exact location of the module I have heard referenced as the Lamp Control Module?

Any help or suggestions would be greatly appreciated.

Thanks,

joe

 

have you checked all the fuses? under the hood and also the passenger side kick panel under the dash at the floor. im sorry i thought you had an ML.. but yes under the seat and under the hood.

 

I was not aware of any fuses other than under the rear seat, and under the hood. I will check in the morning. Thanks for the suggestion!

 

i thought you had an ML.. sorry about that. what car do you have?

 

98 e230 wagon

 

could be a fault with a few other things too. could be a steering angle sensor, or a yaw rate or latteral acceleration sensor too. could be a wheel speed sensor. or even a trans mission issue with the shifter assembly.

 

Are there any tests that can be performed to narrow it down at home?

Do any of them seem more likely with the way the fault was introduced into the system?
