VERIFY FRONT BODY CONTROL MODULE (FBCM) DTCs AGAIN
• Clear the DTC for the front body control module (FBCM) using the M-MDS.
• Switch the ignition ON (engine off or on) and wait for 2 s or more.
• Retrieve the front body control module (FBCM) DTCs using the M-MDS.
• Is the same DTC displayed?
|
Yes
|
Go to the next step.
|
|
No
|
Go to Step 7.

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.
|

INSPECT FOR OPEN CIRCUIT IN IG2 RELAY CONTROL CIRCUIT
• Verify that the start stop unit and front body control module (FBCM) connectors are disconnected.
• Inspect for continuity between start stop unit terminal 2D (wiring harness-side) and front body control module (FBCM) terminal 2U (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 2D and front body control module (FBCM) terminal 2U.
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 6.

VERIFY THAT REPAIRS HAVE BEEN COMPLETED
• Always reconnect all disconnected connectors.
• Reconnect the negative battery cable.
• Clear the DTC for the front body control module (FBCM) using the M-MDS.
• Switch the ignition ON (engine off or on) and wait for 2 s or more.
• Retrieve the front body control module (FBCM) DTCs using the M-MDS.
• Is the same DTC displayed?
|
Yes
|
Repeat the inspection from Step 1.
• If the malfunction recurs, replace the front body control module (FBCM).
Go to the next step.
