Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace harness or connectors.
3. BCM SELF DIAGNOSTIC RESULT
Perform Self Diagnostic Result of BCM with CONSULT. Refer to BCS-24, "BCM : CONSULT Function (BCM - BCM)".
Is DTC B2562 CRNT? YES >> Replace BCM. Refer to BCS-73, "Removal and Installation".
NO >> Refer to GI-39, "Intermittent Incident".
Power supply and ground circuit
Diagnosis procedure
Regarding wiring diagram information, refer to bcs-51, "wiring diagram".
1.Check fuses and fusible link
Check that the following fuses and fusible link are not blown.
Is the fuse blown? Yes >> replace the blown fuse or fusible link after repairing the affected circuit.
No >> go to 2.
2.Check power supply circuit
Is the inspection result normal? Yes >> go to 3.
No >> repair harness or connector.
3.Check ground circuit
Check continuity between BCM connector M85 and ground.
Is the inspection result normal? Yes >> inspection end.
No >> repair harness or connector.
Combination switch input circuit
Diagnosis procedure
