Inspection Between TCM and Data Link Connector CircuitAKS00CFO
1. CHECK HARNESS FOR OPEN CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Disconnect ECM connector and harness connector M82.
4. Check continuity between harness connector M82 terminals 14H (L), 15H (R) and data link connector M5 terminals 6 (L), 14
(R).
OK or NG
OK >> Connect all the connectors and diagnose again. Refer to LAN-7, "
