id0902f5069500

Description

Rear door latch switch (RH) circuit malfunction

Detection condition
•  BCM detects a short to ground in the rear door latch switch (RH) circuit with the rear door (RH) closed (rear door latch switch (RH) off).
Fail-safe
Not applicable
Possible cause
•  Rear door latch and lock actuator (RH) connector or terminal malfunction
•  Rear door latch switch (RH) malfunction
•  BCM connector or terminal malfunction
•  Short to ground in wiring harness between rear door latch and lock actuator (RH) terminal B and BCM terminal 2F
•  BCM malfunction

Diagnostic Procedure

Step

Inspection

Action

1
VERIFY BCM DTCs AGAIN
•  Clear the DTC for the BCM using the M-MDS.
•  Open/close the rear door (RH).
•  Retrieve the BCM DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Go to the next step.
No
Go to Step 7.
2
INSPECT REAR DOOR LATCH AND LOCK ACTUATOR (RH) CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the negative battery cable.
•  Disconnect the rear door latch and lock actuator (RH) connector.
•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 6.
3
INSPECT REAR DOOR LATCH SWITCH (RH)
•  Inspect the rear door latch switch (RH).
•  Is the rear door latch switch (RH) normal?
Yes
Go to the next step.
No
Replace the rear door latch and lock actuator (RH), then go to Step 6.
4
INSPECT BCM CONNECTOR CONDITION
•  Disconnect the BCM connector.
•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 6.
5
INSPECT REAR DOOR LATCH SWITCH (RH) CIRCUIT FOR SHORT TO GROUND
•  Verify that the rear door latch and lock actuator (RH) and BCM connectors are disconnected.
•  Inspect for continuity between rear door latch and lock actuator (RH) terminal B (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Refer to the wiring diagram and verify whether or not there is a common connector between rear door latch and lock actuator (RH) terminal B and BCM terminal 2F.
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness which has a short to ground.
Go to the next step.
No
Go to the next step.
6
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  Always reconnect all disconnected connectors.
•  Connect the negative battery cable.
•  Clear the DTC for the BCM using the M-MDS.
•  Open/close the rear door (RH).
•  Retrieve the BCM DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the BCM.
Go to the next step.
No
Go to the next step.
7
VERIFY IF OTHER DTCs DISPLAYED
•  Are any other DTCs displayed?
Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
