Diagnostic Procedure

STEP

INSPECTION

ACTION
1
CONFIRM THEFT-DETERRENT CONTROL MODULE DTC
•  Clear the DTC using the M-MDS.
•  Perform the theft-deterrent control module DTC inspection using the M-MDS with the bonnet closed (bonnet latch switch on).
•  Is the same DTC present?
Yes
Go to the next step.
No
Go to Step 9.
2
INSPECT BONNET LATCH SWITCH CONNECTOR AND TERMINALS
•  Switch the ignition to off.
•  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 8.
No
Go to the next step.
3
VERIFY MALFUNCTIONING LOCATION
•  Bonnet latch switch connector is disconnected.
•  Reconnect the negative battery cable.
•  Measure the voltage at the following terminal (wiring harness-side):
―  Bonnet latch switch terminal A
•  Is there any voltage?
Yes
Go to the next step.
No
Go to Step 6.
4
INSPECT BONNET LATCH SWITCH CIRCUIT FOR OPEN CIRCUIT
•  Bonnet latch switch connector is disconnected.
•  Disconnect the negative battery cable.
•  Inspect for continuity between the following terminal (wiring harness-side) and body ground:
―  Bonnet latch switch terminal B
•  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 8.
5
INSPECT BONNET LATCH SWITCH
•  Inspect the bonnet latch switch.
•  Is there any malfunction?
Yes
Replace the bonnet latch switch, then go to Step 8.
(See BONNET LATCH AND RELEASE LEVER REMOVAL/INSTALLATION.)
No
Go to Step 8.
6
INSPECT THEFT-DETERRENT CONTROL MODULE CONNECTOR AND TERMINALS
•  Disconnect the negative battery cable.
•  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.
7
INSPECT BONNET LATCH SWITCH CIRCUIT FOR OPEN CIRCUIT
•  Bonnet latch switch and theft-deterrent control module connectors are disconnected.
•  Reconnect the theft-deterrent control module connector.
•  Reconnect the negative battery cable.
•  Measure the voltage at the following terminal (wiring harness-side):
―  Theft-deterrent control module terminal H
•  Is there any voltage?
Yes
Repair or replace the wiring harness for a possible open circuit, then go to the next step.
No
Go to the next step.
8
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC using the M-MDS.
•  Perform the theft-deterrent control module DTC inspection using the M-MDS with the bonnet closed (bonnet latch switch on).
•  Is the same DTC present?
Yes
Replace the theft-deterrent control module, then go to the next step.
(See THEFT-DETERRENT CONTROL MODULE REMOVAL/INSTALLATION.)
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 [THEFT-DETERRENT SYSTEM].)
No
DTC troubleshooting completed.
