Service Ride Control Still On/out Of Ideas-help

[alvocado]

I'm out of ideas and need some advice before resorting to a trip to the dealer. My "Service Ride Control" light came on after changing my shocks in July with OEM Delphi units. I noticed the compressor stopped running at the time the shocks were replaced so I installed a new GM compressor. The compressor runs as expected about 5 seconds after I start the truck. However, once I begin to drive the truck, the warning light illuminates and stays on until I shutoff the engine. The light doesn't come on after startup as long as I don't move so I'm assuming it's being triggered by some signal the controller is getting after the vehicle moves in either reverse or drive. I took the truck to Autzone to see if any codes were available but their OBDII scan tool couldn't detect any. The light also wasn't on because it only trips after the vehicle moves.

 

I checked for continuity on all for shocks yesterday and read 2.5ohms on the rears and 15.8ohms on the fronts. That was in spec according to the values I received from tech support at Arnott Industries where I purchased the OEM replacements. I'm hesitant to take the truck to my indy mechanic if a dealer-only system is needed for further troubleshooting or resets.

 

This light is getting really annoying. I would greatly appreciate any advice from someone with knowledge of the autoride systems. Thanks in advance.

A friend pulled a c0625 code on the truck but everytime he reset it, the code would register again. I found the code info online as "Left rear position sensor malfunction." Anyone familiar with this?
