--- | ---
DETECTION CONDITION | • Open circuit in bonnet latch switch circuit with bonnet closed (bonnet latch switch on).
POSSIBLE CAUSE | • Bonnet latch switch connector or terminals malfunction • Open circuit in wiring harness between bonnet latch switch terminal B and body ground • Bonnet latch switch malfunction • Theft-deterrent control module connector or terminals malfunction • Open circuit in wiring harness between bonnet latch switch terminal A and theft-deterrent control module terminal H • Theft-deterrent control module malfunction

Diagnostic Procedure

Step | Inspection | Action
--- | --- | ---
1 | INSPECT BONNET LATCH SWITCH CONNECTOR AND TERMINALS • Turn the ignition switch to the OFF position. • Disconnect the negative battery cable. • Disconnect the bonnet 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 6.
No | Go to the next step.
2 | INSPECT BONNET LATCH SWITCH GROUND CIRCUIT FOR OPEN CIRCUIT • Verify that the bonnet latch switch connector is disconnected. • Inspect for continuity between the bonnet latch switch terminal B (wiring harness-side) and body ground. • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness for a possible open circuit, then go to Step 6.
3 | INSPECT BONNET LATCH SWITCH • Inspect the bonnet latch switch. (See BONNET LATCH SWITCH INSPECTION.) • Is there any malfunction? | Yes | Replace the bonnet latch switch, then go to Step 6. (See BONNET LATCH AND RELEASE LEVER REMOVAL/INSTALLATION.)
No | Go to the next step.
4 | INSPECT THEFT-DETERRENT CONTROL MODULE CONNECTOR AND TERMINALS • Disconnect the theft-deterrent control module 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.
No | Go to the next step.
5 | INSPECT BONNET LATCH SWITCH CIRCUIT FOR OPEN CIRCUIT • Verify that the bonnet latch switch and theft-deterrent control module connectors are disconnected. • Inspect for continuity between the bonnet latch switch terminal A (wiring harness-side) and theft-deterrent control module terminal H (wiring harness-side). • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness for a possible open circuit, then go to the next step.
6 | VERIFY TROUBLESHOOTING COMPLETED • Make sure to reconnect the disconnected connectors. • Reconnect the negative battery cable. • Clear the DTC using the M-MDS. (See CLEARING DTC [THEFT-DETERRENT SYSTEM].) • Perform the theft-deterrent control module DTC inspection using the M-MDS with bonnet closed (bonnet latch switch on). (See DTC INSPECTION [THEFT-DETERRENT SYSTEM].) • Is the same DTC present? | Yes | Repeat the inspection from Step 1. • If the malfunction recurs, replace the theft-deterrent control module. (See THEFT-DETERRENT CONTROL MODULE REMOVAL/INSTALLATION.) Go to the next step.
No | Go to the next step.
7 | VERIFY THAT NO OTHER DTCs ARE PRESENT • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [THEFT-DETERRENT SYSTEM].)
No | DTC troubleshooting completed.
