Hey all!

This past weekend Bush Buster and I set about installing a 2" coil spacer lift in my 2003 Tracker ZR2. It went relatively smoothly, minus a sheared bolt on the passenger side knuckle... great way to spend 2 hours LOL.  After getting it back on the road, I have a few questions...   My ABS light is consistently on now, and Im not too sure why.   We did end up stretching the driver side sensor wire pretty good,    didn't break it or anything, but did manage to distress the rubber casing. Could this throw the sensor? Bush buster's rig doesn't have ABS, and therefore, he never had to deal with this when he lifted his. Also, I was told I need to relocate a "rise height" sensor in the back attached to the frame. a) could this be throwing the ABS?     and     b) where is it, and how do I relocate it? just make a bracket to lower it to its original  height after lift and tires?    This needs to be done to allow the rear drum breaks to start working properly again... am I on the right track?      Thanks ladies and gents,   any help would be much appreciated.   I will upload pics as soon as I figure out how small I need to resize them lol... for a 20 something, im useless with computers!

I would strongly suspect a damaged or disconnected ABS sensor - have the code read it will point you to the problem area - there are usually two codes per sensor , one if it doesn't detect the sensor at power up, and a second if it does the detect the sensor, but doesn't see a pulse train from the sensor after the vehicle starts to move.

Rise height sensor at the rear - never heard of it.

Some vehicles will have an LSPV, what this does is adjust the rear brake effort based on the load in the vehicle, which it senses based on the ride height, or more accurately the distance between the axle & the frame - this LSPV may be what you were told about.

The LSPV is old technology, the same compensation can be done with the ABS, but, some early ABS vehicles still have the LSPV, a "non-ABS" Tracker will have the LSPV on the right frame rail, connected to the axle with a spring - I don't think the ABS equipped Trackers do, but all you need to do to confirm is to follow the brake lines down the frame rail and see where they go, if they end up at a contraption connected to the axle with a spring, then you have an LSPV - make a bracket to extend the spring mount on the axle by whatever height you lifted the rear.
