Diagnostic Procedure

STEP

INSPECTION

ACTION
1
CONFIRM BCM DTC
•  Clear the DTC using the M-MDS.
•  Perform the BCM DTC inspection using the M-MDS with the rear door (RH) closed (rear door latch switch (RH) on).
•  Is the same DTC present?
Yes
Go to the next step.
No
Go to Step 9.
2
INSPECT REAR DOOR LATCH AND LOCK ACTUATOR (RH) CONNECTOR AND TERMINALS
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Disconnect the rear door latch and lock actuator (RH) 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
•  Rear door latch and lock actuator (RH) connector is disconnected.
•  Reconnect the negative battery cable.
•  Measure the voltage at the following terminal (wiring harness-side):
―  Rear door latch and lock actuator (RH) terminal B
•  Is there any voltage?
Yes
Go to the next step.
No
Go to Step 6.
4
INSPECT REAR DOOR LATCH SWITCH (RH) CIRCUIT FOR OPEN CIRCUIT
•  Rear door latch and lock actuator (RH) connector is disconnected.
•  Disconnect the negative battery cable.
•  Inspect for continuity between the following terminal (wiring harness-side) and body ground:
―  Rear door latch and lock actuator (RH) terminal D
•  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 REAR DOOR LATCH SWITCH (RH)
•  Inspect the rear door latch switch (RH).
•  Is there any malfunction?
Yes
Replace the rear door latch and lock actuator (RH), then go to Step 8.
(See REAR DOOR LATCH AND LOCK ACTUATOR REMOVAL/INSTALLATION.)
No
Go to Step 8.
6
INSPECT BCM CONNECTOR AND TERMINALS
•  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.
No
Go to the next step.
7
INSPECT REAR DOOR LATCH SWITCH (RH) CIRCUIT FOR OPEN CIRCUIT
•  Rear door latch and lock actuator (RH) and BCM connectors are disconnected.
•  Reconnect the BCM connector.
•  Reconnect the negative battery cable.
•  Measure the voltage at the following terminal (wiring harness-side):
―  BCM terminal 6K
•  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 BCM DTC inspection using the M-MDS with the rear door (RH) closed (rear door latch switch (RH) on).
•  Is the same DTC present?
Yes
Replace the BCM, then go to the next step.
(See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION [L.H.D.].)
(See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION [R.H.D.].)
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].)
No
DTC troubleshooting completed.
