Diagnostic Procedure

STEP	INSPECTION		ACTION
1	VERIFY BCM DTCs Clear the DTC using the M-MDS. (See CLEARING DTC [BCM] .) Perform the BCM DTC inspection using the M-MDS. (See DTC INSPECTION [BCM] .) Is the same DTC present?	Yes	Go to the next step.
1		No	Go to Step 9.
2	INSPECT HOOD LATCH SWITCH CONNECTOR AND TERMINALS Switch the ignition to off. Disconnect the negative battery cable. Disconnect the hood latch switch connector. Inspect the connector and terminals (corrosion, damage, pin disconnection). Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 8.
2		No	Go to the next step.
3	DETERMINE MALFUNCTIONING LOCATION Verify that the hood latch switch connector is disconnected. Reconnect the negative battery cable. Switch the ignition to ON. Measure the voltage at the hood latch switch terminal A (wiring harness-side). Is there any voltage?	Yes	Go to the next step.
3		No	Go to Step 6.
4	INSPECT HOOD LATCH SWITCH GROUND CIRCUIT FOR OPEN CIRCUIT Verify that the hood latch switch connector is disconnected. Switch the ignition to off. Disconnect the negative battery cable. Inspect for continuity between hood latch switch terminal B (wiring harness-side) and body ground. Is there continuity?	Yes	Go to the next step.
4		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 8.
5	INSPECT HOOD LATCH SWITCH Inspect the hood latch switch. (See HOOD LATCH SWITCH INSPECTION .) Is there any malfunction?	Yes	Replace the hood latch switch, then go to Step 8. (See HOOD LATCH AND RELEASE LEVER REMOVAL/INSTALLATION .)
5		No	Go to Step 8.
6	INSPECT BCM CONNECTOR AND TERMINALS Switch the ignition to off. Disconnect the negative battery cable. Disconnect the BCM connector. Inspect the connector and terminals (corrosion, damage, pin disconnection). Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 8.
6		No	Go to the next step.
7	INSPECT HOOD LATCH SWITCH CIRCUIT FOR OPEN CIRCUIT Make sure to reconnect all disconnected connectors. Reconnect the negative battery cable. Switch the ignition to ON. Measure the voltage at the BCM terminal 1J (wiring harness-side). Is there any voltage?	Yes	Repair or replace the wiring harness for a possible open circuit, then go to the next step.
7		No	BCM internal malfunction can be considered the cause. Go to the next step.
8	VERIFY TROUBLESHOOTING COMPLETED Make sure to reconnect all disconnected connectors. Reconnect the negative battery cable. Clear the DTC using the M-MDS. (See CLEARING DTC [BCM] .) Perform the BCM DTC inspection using the M-MDS. (See DTC INSPECTION [BCM] .) Is the same DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the BCM. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION .) Go to the next step.
8		No	Go to the next step.
9	VERIFY THAT NO OTHER DTCs ARE PRESENT Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [BCM] .)
9		No	DTC troubleshooting completed.
