Electronic Control System

PCM monitors transaxle operation. PCM contains an electronic control system which stores a Diagnostic Trouble Code (DTC) if a transaxle electronic control system failure or problem exists. If DTC is stored, PCM flashes "D4" indicator light on A/T gear position indicator on instrument panel. If a transaxle electronic control system failure or problem is suspected and "D4" indicator light on A/T gear position indicator does not flash, perform diagnostic circuit check to ensure proper operation of "D4" indicator light. DTC can be retrieved using scan tool connected to Data Link Connector (DLC) located behind ashtray. Flash code may also be retrieved for diagnosing transaxle electronic control system, using the "D4" indicator light.
