C0201 Abs Code Problem

[armboy9589]

I have a 2004 2500 HD with the codes:

C0201 ABS Enable Relay Contact Circuit

C0035 LF Wheel Speed sensor

C0040 RF Wheel Speed Sensor

 

I have cleaned the ground for the EBCM and that did not solve the problem wondering if anyone has had this happen or know of a way to solve it or what the resistance should be in a wheel sensor. I just have a hard time believing that both sensors would go out at the same time or if it is a common problem.

Thanks A lot Chad

Hey Chad, welcome to the site. Wheel speed sensors should be about 700-10,000 ohms. I hate to guess at things but there isn't much guidance I can give on paper on this set of codes, so all I can say is that usually if you have the C201 in this vehicle and fixing the ground doesn't help then the Electronic Brake Control Module is the fault. I hate to have you guess and have that not be it because it is expensive. Good luck to ya.

Are these modules a common problem i just dont know much about GM vehicles and their common problems.

No they are not very common. I would have someone check it out before guessing at this part.
