.
• Open or short-circuit in the harness between TCM and the starter relay. Refer to CVT-61, "
Wiring Diagram -
CVT - STSIG" .
• Ground circuit for the starter relay. Refer to SC-10, "
Wiring Diagram - START -" .
OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts.
3.CHECK DTC
Perform CVT-60, "
DTC Confirmation Procedure" .
OK or NG
OK >>INSPECTION END
NG >> GO TO 4.
4.CHECK TCM
1. Check TCM input/output signals. Refer to CVT-45, "
TCM Terminal and Reference Value" .
2. If NG, re-check TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK >>INSPECTION END
NG >> Repair or replace damaged parts.
