I finally got a USA East navigation CD, so I can calibrate the navigation system ... however, prior to starting calibration, I have to 'test' the GPS and Wheel Speed Sensors ... but when I go to do that, the GPS registers, but the wheel speed sensors seem to be 'out of order' ... i.e. the speed readout stays at 000 instead of showing me the speed I'm going.

So, to the point ... does anyone know where the wheel speed sensors are located? How to get to them? How easy they are to 'fix' if it turns out one or more of mine are broken? I've been searching the net for a schematic or exploded diagram of the truck to find the sensors, but have been quite unsuccessful so far ...

any help would be great ... thanks!

 

You have one wheel speed sensor in each wheel hub.
If they were not working your 3 brake warning lights would be on. Must be something else causing this problem and i am not familiar with the Nav systems.

ok ... that's good to know ... I'm not getting any errors, so the sensors must be ok ... perhaps it's just the lead from the sensors to the radio/nav system ... I'll have to check that out. Thanks!
