System Diagnosis

NOTE: Before testing transaxle, ensure fluid level is correct and throttle and shift cables are properly adjusted. Ensure engine starts with gear selector lever in "P" and "N" positions to ensure proper adjustment of Transmission Range (TR) switch. The electronic control system must first be checked for stored DTCs. See RETRIEVING TROUBLE CODES .

The TCM monitors transaxle operation and contains a self-diagnostic system which stores a Diagnostic Trouble Code (DTC) if an electronic control system malfunction is detected. If a malfunction is detected and a DTC is set, the TCM will deliver a signal to flash OD/OFF indicator on instrument cluster to warn the driver.

The number of OD/OFF indicator flashes will equal first digit of DTC. After a one second pause, second digit of DTC is displayed. If more than one DTC is present, the next DTC will be displayed after a 3 second pause. Smallest number DTC will be displayed first. DTCs are repeated after each retrieval cycle. Once a DTC is retrieved, determine probable cause. See DTC IDENTIFICATION .
