VERIFY REAR BODY CONTROL MODULE (RBCM) DTCs AGAIN
• Clear the DTC for the rear body control module (RBCM) using the M-MDS.
• Retrieve the rear body control module (RBCM) DTCs using the M-MDS.
• Is the same DTC displayed?
|
Yes
|
Go to the next step.
|
|
No
|
Go to Step 8.

INSPECT START STOP UNIT CONNECTOR CONDITION
• Switch the ignition off.
• Disconnect the negative battery cable.
• Disconnect the start stop unit 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 7.

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

INSPECT FOR SHORT TO GROUND IN WIRING HARNESS BETWEEN START STOP UNIT AND REAR BODY CONTROL MODULE (RBCM)
• Verify that the rear body control module (RBCM) and start stop unit connectors are disconnected.
• Inspect for continuity between start stop unit terminal 1Q (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 body control module (RBCM) terminal 3B and start stop unit terminal 1Q.
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 7.
|
|
No
|
Go to the next step.

|
INSPECT FOR OPEN CIRCUIT IN WIRING HARNESS BETWEEN START STOP UNIT AND REAR BODY CONTROL MODULE (RBCM)
• Verify that the rear body control module (RBCM) and start stop unit connectors are disconnected.
• Inspect for continuity between rear body control module (RBCM) terminal 3B (wiring harness-side) and start stop unit terminal 1Q (wiring harness-side).
• Is there continuity?
|
Yes
|
Go to the next step.
|
|
No
|
Refer to the wiring diagram and verify whether or not there is a common connector between rear body control module (RBCM) terminal 3B and start stop unit terminal 1Q.
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 an open circuit.
• Repair or replace the malfunctioning part.
If there is no common connector:
• Repair or replace the wiring harness which has an open circuit.
Go to Step 7.

PERFORM DTC INSPECTION AND VERIFY START STOP UNIT MALFUNCTION
• Always reconnect all disconnected connectors.
• Reconnect the negative battery cable.
• Clear the DTC for the rear body control module (RBCM) using the M-MDS.
• Retrieve the rear body control module (RBCM) DTCs using the M-MDS.
• Is the same DTC displayed?
|
Yes
|
Replace the start stop unit, then go to the next step.
|
|
No
|
Go to Step 8.

VERIFY THAT REPAIRS HAVE BEEN COMPLETED
• Always reconnect all disconnected connectors.
• Reconnect the negative battery cable.
• Clear the DTC for the rear body control module (RBCM) using the M-MDS.
• Retrieve the rear body control module (RBCM) DTCs using the M-MDS.
• 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.

|
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.
