DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK CONNECTOR. Check the installing condition of TCM connector.	Is the TCM connector installed properly?	Go to step 2 .	Install the TCM connector.
2 CHECK INPUT VOLTAGE OF TCM. Turn the ignition switch to ON. Measure the voltage between TCM connector and chassis ground. (While wiggling the harness) Connector & terminal ENGINE TYPE FB (T10) No. 41 (+) - Chassis ground (-): ENGINE TYPE EZ (B54) No. 41 (+) - Chassis ground (-):	Is the voltage 8 V or more?	Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again. NOTE: In this case, the following items may be the cause of fault. Open circuit or short circuit to ground of harness between TCM connector and ignition switch connector (IG relay 1 connector for model with push button start) Poor contact of ignition switch connector (IG relay 1 connector for model with push button start) Poor contact of ignition switch (IG relay 1 for model with push button start)	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit or short circuit to ground of harness between TCM connector and ignition switch connector (IG relay 1 connector for model with push button start) Poor contact of ignition switch connector (IG relay 1 connector for model with push button start) Poor contact of ignition switch (IG relay 1 for model with push button start)
