Re: StabiliTrak Deactivation for California Smog Test
I had to do this to dyno my car. The other option, pull the rear wheel speed sensor plugs (under the car).
I think California is one of the few states still running a dyno (load test), for emissions testing. Most are all OBDII scan, checking for current DTC's, EVAP system performance (the old gas cap test), that all readiniess monitors (I/M system in GM speak), are online, functioning and have run/passed their criteria and not commanding the MIL on, and mileage since last code cleared. So the old IM240 roller test it isn't an issue.
