VERIFY BCM DTCs AGAIN
• Clear the DTC for the BCM using the M-MDS.
• Lock/unlock all the doors by operating the driver’s door lock knob.
• Retrieve the BCM DTCs using the M-MDS.
• Is the same DTC displayed?
|
Yes
|
Go to the next step.

INSPECT FRONT DOOR LATCH AND LOCK ACTUATOR (DRIVER'S SIDE) CONNECTOR CONDITION
• Switch the ignition off.
• Disconnect the negative battery cable.
• Disconnect the front door latch and lock actuator (driver's side) 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 8.

• Is the front door lock-link switch (driver's side) normal?
|
Yes
|
Go to the next step.
|
|
No
|
Replace the front door latch and lock actuator (driver's side), then go to Step 8.

|
Yes
|
Go to the next step.
|
|
No
|
Repair or replace the connector, then go to Step 8.

INSPECT FRONT DOOR LOCK-LINK SWITCH (DRIVER'S SIDE) LOCK CIRCUIT FOR SHORT TO GROUND
• Verify that the front door latch and lock actuator (driver's side), start stop unit and BCM connectors are disconnected.
• Inspect for continuity between the following terminals (wiring harness-side) and body ground:
-
― Front door latch and lock actuator (LH) terminal D (L.H.D.)
― Front door latch and lock actuator (RH) terminal J (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.:
-
― Front door latch and lock actuator (LH) terminal D—BCM terminal 2A—
― Start stop unit terminal 1P—Front door latch and lock actuator (LH) terminal D
• R.H.D.:
-
― Front door latch and lock actuator (RH) terminal J—BCM terminal 2A
― Start stop unit terminal 1P—Front door latch and lock actuator (RH) terminal J
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 Step 8.

|
INSPECT START STOP UNIT
• Inspect the start stop unit.
• Is the start stop unit normal?
|
Yes
|
Go to the next step.
|
|
No

• Connect the negative battery cable.
• Clear the DTC for the BCM using the M-MDS.
• Lock/unlock all the doors by operating the driver’s door lock knob.
• 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.
