Pinout Values and Diagnostic Parameters

Inspection of TCM and Its Circuits
TCM and its circuits can be checked at TCM wiring connectors by measuring voltage and resistance.

CAUTION: TCM cannot be checked by itself, it is strictly prohibited to connect voltmeter or ohmmeter to TCM with connector disconnected from it.

Inspection
1. Remove TCM (1) from vehicle.
2. Connect TCM connectors (2) to TCM.





3. Check voltage at each terminal of connectors connected.

NOTE: As each terminal voltage is affected by battery voltage, confirm that it is 11 V or more when ignition switch is ON.
