Hello,

I appreciate you welcoming me into the community. I am a mechanical engineer with a background heavily in engine/combustion development, but I began "life" as a mechanic. I also spent 6 years as an engine calibration engineer at Ford, but I'm now pivoting out of the auto industry.

I have a 2009 Chevy Express 3500 6.0L that is experiencing the Stabilitrak fault, and I would like to diagnose this issue. My first order is to start looking at the PCM data over CAN. I'm not really interested in changing calibrations at all, just want it to run without the fault. I have a KVASER HS CAN interface, but I'm curious if anyone here could point me to the OBDII PID definition file that will allow me to start looking at this. Any help is much appreciated.

-Joshua

Stabilitrak is not a function of the PCM. Just pick up a code reader that will read B (Body) and C (Chassis) codes and that should steer you towards what the fault is.
