WITH INTELLIGENT KEY SYSTEM : Diagnosis Procedure
Regarding Wiring Diagram information, refer to BCS-50, "Wiring Diagram".
1. CHECK FUSE
Check that the following fuse is not blown.
| Terminal No. | Signal name | Fuse No. |
| 161 | BCM power supply | 7 (10A) |
Is the fuse blown? YES >> Replace the blown fuse after repairing the affected circuit.
NO >> GO TO 2.
2. CHECK POWER SUPPLY CIRCUIT
| BCM | Ground | Voltage (Approx.) | |
| Connector | Terminal | ||
| M20 | 161 | — | Battery voltage |
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace harness or connectors.
3. CHECK GROUND CIRCUIT
Check continuity between BCM connector M20 and ground.
| BCM | Ground | Continuity | |
| Connector | Terminal | ||
| M20 | 170 | — | Yes |
| 171 | |||
Is the inspection result normal? YES >> Inspection End.
NO >> Repair or replace harness or connectors.
