Conditions for Setting the DTC

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

After the ignition is turned to RUN, the ESC module does not detect a low to high transition on the chassis pitch angle signal circuit from the PCM.
The ESC module will continue to send a request every 4 minutes to the PCM in order to retest for a chassis pitch circuit malfunction.
The condition must be detected within 31 seconds.
