TROUBLE DIAGNOSIS FOR SYSTEM
Revision: 2006 December 2006 FX35/FX45
TROUBLE DIAGNOSIS FOR SYSTEMPFP:00000
Inspection Between TCM and Data Link Connector CircuitNKS0038T
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 and data link con- nector.
OK or NG
