Inspection of TCM and Its Circuits: Notes

WARNING: This page is about a different car, the 2011 Suzuki SX4. However, it is still accessible from the selected car via links, so may be relevant.

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.
