2. Check voltage between BCM connector and ground.





OK or NG





OK - Check the condition of harness and connector.
NG - Replace BCM.

CHECK HOOD SWITCH
1.CHECK HOOD SWITCH
Check hood switch and hood fitting condition.
OK or NG
OK - GO TO 2.
NG - Adjust installation of hood switch.
2.CHECK HOOD SWITCH INPUT SIGNAL
With CONSULT-III
Check ("HOOD SW") in "DATA MONITOR" mode with CONSULT-III.
- When hood is opened:

2. Check continuity between hood switch connector and IPDM E/R connector.





3. Check continuity between hood switch connector and ground.





OK or NG
OK - GO TO 5.
NG - Repair or replace hood switch harness.
5.CHECK HOOD SWITCH GROUND CIRCUIT





Check continuity between hood switch connector and ground.





OK or NG
OK - Check condition of harness and connector.
NG - Repair or replace hood switch harness.

CHECK TRUNK ROOM LAMP SWITCH
1.CHECK TRUNK ROOM LAMP SWITCH INPUT SIGNAL
With CONSULT-III
Check ("TRUNK SW") in "DATA MONITOR" mode with CONSULT-III.

OK or NG
OK - GO TO 3.
NG - Replace trunk room lamp switch.
3.CHECK TRUNK ROOM LAMP SWITCH CIRCUIT
1. Disconnect BCM connector.
2. Check continuity between BCM connector and trunk lid lock assembly connector.










3. Check continuity between BCM connector and ground.





OK or NG
OK - GO TO 4.
NG - Repair or replace harness between BCM and trunk room lamp switch.
4.CHECK TRUNK ROOM LAMP SWITCH GROUND CIRCUIT
Check continuity between trunk lid lock assembly connector and ground.










OK or NG
OK - GO TO 5.
NG - Repair or replace trunk room lamp switch ground circuit.
5.CHECK BCM OUTPUT SIGNAL
