Hi,

By chance, do you have the codes that are stored? Also, I need to know if this vehicle is 4wd and the engine size.

If I have the code, it will help point me in the right direction for diagnostics. Keep in mind, it could be related to a rear wheel speed sensor as well. If it has 4-wheel ABS, there are two sensors on the rear. On the other hand, it could have what is called 3-channel ABS which only has one in the rear-mounted at the top of the differential. There could be a variation between that sensor and the front causing an issue.

Let me know.

Joe

See pics below for sensor locations. Pic 1 = 4 channel (one on each rear wheel). Pic 2 = 3 channel.
