Monitor modules and PCM sensor values in Current Data, check and wiggle the harness(es), connector(s), and terminal(s).

Any change in the values indicates a poor connection. Was a connector problem found?

	▶ Repair the connector. Go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Signal Circuit Inspection" procedure.

IG "OFF". Disconnect PCM and TCM connector.

Check resistance between CAN-HIGH terminal of PCM harness Connector and CAN-HIGH terminal of TCM harness connector.

Check resistance between CAN-LOW terminal of PCM harness Connector and CAN-LOW terminal of TCM harness connector.

Is the measured resistance within specification ?

	▶ Go to "Component Inspection".
	▶ Repair open in CAN BUS line. Go to "Verification of Vehicle Repair".
