Detection condition
•  With the rear door (LH) closed (rear door latch switch (LH) off), the rear body control module (RBCM) detects a short to ground in the rear door latch switch (LH) circuit.
Fail-safe
Possible cause
•  Rear door latch and lock actuator (LH) connector or terminal malfunction
•  Rear door latch switch (LH) malfunction
•  Rear body control module (RBCM) connector or terminal malfunction
•  Short to ground in wiring harness between rear body control module (RBCM) terminal 3S and rear door latch and lock actuator (LH) terminal L
•  Rear body control module (RBCM) malfunction

Diagnostic Procedure

Step

Inspection

Action

1
VERIFY REAR BODY CONTROL MODULE (RBCM) DTCs AGAIN
•  Clear rear body control module (RBCM) DTCs using the M-MDS.
•  Perform the DTC inspection for the rear body control module (RBCM) using the M-MDS.
•  Is DTC B11E9:11 displayed?
Yes
Go to the next step.
No
Go to Step 7.
2
INSPECT REAR DOOR LATCH AND LOCK ACTUATOR (LH) CONNECTOR
•  Switch the ignition to off.
•  Disconnect the rear door latch and lock actuator (LH) 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 (LH)
•  Inspect the rear door latch switch (LH).
•  Is the rear door latch switch (LH) normal?
Yes
Go to the next step.
No
Replace the rear door latch and lock actuator (LH), then go to Step 6.
4
INSPECT REAR BODY CONTROL MODULE (RBCM) CONNECTOR CONDITION
•  Disconnect the rear body control module (RBCM) 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 (LH) CIRCUIT FOR SHORT TO GROUND
•  Verify that the rear body control module (RBCM) connector and rear door latch and lock actuator (LH) connector are disconnected.
•  Inspect for continuity between rear door latch and lock actuator (LH) terminal L (vehicle wiring harness) and body ground.
•  Is there continuity?
Yes
Repair or replace the wiring harness which has a short to ground, then go to the next step.
No
Go to the next step.
6
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  Reconnect all the disconnected connectors.
•  Clear rear body control module (RBCM) DTCs using the M-MDS.
•  Perform the DTC inspection for the rear body control module (RBCM) using the M-MDS.
•  Is DTC B11E9:11 displayed?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the rear body control module (RBCM), then go to the next step.
No
Go to the next step.
7
VERIFY IF OTHER DTCs DISPLAYED
•  Are any other DTCs displayed?
Yes
Repair the malfunctioning part according to the applicable DTC troubleshooting.
