ABS light on 98' chev 4x4

darc · 05-09-2007, 11:16 PM

My ABS light keeps coming on an d my mechanic is having some difficulty diagnosing the problem. The Code Reader is showing that the left front wheel speed sensor is missing and the right front wheel speed sensor is reading erratic. To date they have replaced the left front wheel speed sensor with a new one, this did not have any effect. Then they figured it was the ABS module and proceeded to replace this with a used one, again the problem was not rectified. It was then thought that the used ABS module was defective and it was repalced with another, this to had no effect on the problem. The brakes work fine with the exception of the ABS. can any one give me a hint to what is going on.

sounds like you need to take it to a mechanic that dosn't guess at what the problem is. what year is the truck? is he using an ordinary scan tool or one made to diagnose ABS systems? do you know the code numbers it is throwing?
