VERIFY BCM DTCs AGAIN
• Clear the DTC for the BCM using the M-MDS.
• Retrieve the BCM 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 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 7.

INSPECT WIRING HARNESS BETWEEN START STOP UNIT AND BCM FOR SHORT TO GROUND
• Verify that the start stop unit and BCM 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 start stop unit terminal 1Q and BCM terminal 2J.
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 WIRING HARNESS BETWEEN START STOP UNIT AND BCM FOR OPEN CIRCUIT
• Verify that the start stop unit and BCM connectors are disconnected.
• Inspect for continuity between start stop unit terminal 1Q (wiring harness-side) and BCM terminal 2J (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 start stop unit terminal 1Q and BCM terminal 2J.
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.

VERIFY IF MALFUNCTIONING LOCATION IS START STOP UNIT DEPENDING ON REPEATABILITY
• Always reconnect all disconnected connectors.
• Connect the negative battery cable.
• Clear the DTC for the BCM using the M-MDS.
• Retrieve the BCM 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.
• Connect the negative battery cable.
• Clear the DTC for the BCM using the M-MDS.
• 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.

|
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.
