INSPECT FOR SHORT TO GROUND IN DOOR LOCK-LINK SWITCH UNLOCK CIRCUIT
• Verify that the rear body control module (RBCM), front door latch and lock actuator (passenger's side), rear door latch and lock actuator (LH) and (RH) connectors are disconnected.
• Inspect for continuity between the following terminal (wiring harness-side) and body ground:
-
― Front door latch and lock actuator (RH) terminal L (L.H.D.)
― Front door latch and lock actuator (LH) terminal B (R.H.D.)
• Is there continuity?
|
Yes
|
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
• L.H.D.:
-
― Rear body control module (RBCM) terminal 3J—Front door latch and lock actuator (RH) terminal L
― Rear body control module (RBCM) terminal 3J—Rear door latch and lock actuator (LH) terminal B
― Rear body control module (RBCM) terminal 3J—Rear door latch and lock actuator (RH) terminal L
• R.H.D.:
-
― Rear body control module (RBCM) terminal 3J—Front door latch and lock actuator (LH) terminal B
― Rear body control module (RBCM) terminal 3J—Rear door latch and lock actuator (LH) terminal B
― Rear body control module (RBCM) terminal 3J—Rear door latch and lock actuator (RH) terminal L
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.

• Is the same DTC displayed?
|
Yes
|
Repeat the inspection from Step 1.
• If the malfunction recurs, replace the rear body control module (RBCM).
Go to the next step.
