DESCRIPTION

The self-diagnosis system integrated in the powertrain control module (Transaxle) diagnoses malfunctions of the main sensors (input) and solenoid valves (output) and the powertrain control module (Transaxle) itself. Malfunctions or intermittent malfunctions are memorized in the powertrain control module (Transaxle) to later be output as diagnostic trouble codes.

The Self-Diagnosis Checker can be used to retrieve these diagnostic trouble codes. The Self-Diagnosis Checker indicates a malfunction by displaying a code number and sounding a buzzer.

When the TAT and GND terminals of the data link connector are shorted with the ignition switch ON, the powertrain control module (Transaxle) outputs any memorized diagnostic trouble codes by flashing the hold indicator.
