On certain vehicles, the Electronically Controlled Air Suspension (ECAS) may produce a brief electrical spike while the vehicle is operating. This electrical spike can disrupt the Powertrain Control Module (PCM) causing the vehicle to stall. If the spike damages the PCM, the vehicle may not restart. Correction: Problem previously addressed by Technical Service Bulletin A001831 in January 2002.
