Inspection of TCM and Its Circuits: Notes
WARNING: This page is about a different car, the 2010 Suzuki Kizashi. 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 pulse signal.
CAUTION:
It is strictly prohibited to connect voltmeter or ohmmeter to TCM with connector disconnected from it.
