Inspection of TCM and Its Circuits: Notes

TCM and its circuits can be checked at TCM wiring connectors by measuring voltage and resistance.

CAUTION: If you connect a voltmeter or ohmmeter directly to the ECM terminals by removing the TCM connectors, you can damage the TCM. Never connect a voltmeter or an ohmmeter directly to any terminal on the TCM by disconnecting the TCM connectors.
