|
Step |
Inspection |
Results |
Action |
|---|---|---|---|
|
1
|
INSPECT VEHICLE CONTROL MODULE (VCM) AND BODY CONTROL MODULE (BCM) FOR MALFUNCTION
• Perform the DTC inspection for the vehicle control module (VCM) and the body control module (BCM).
(See DTC INSPECTION.)
• Is a DTC related to an internal malfunction displayed?
|
Yes
|
Repair the malfunctioning location according to the applicable DTC troubleshooting.
|
|
No
|
Go to the next step.

(See DTC INSPECTION.)
• Is a DTC displayed?
|
Yes
|
Repair the malfunctioning location according to the applicable DTC troubleshooting.
|
|
No
|
Go to the next step.
|
||
|
3
|
VERIFY REPLACEMENT RECORD OF FORWARD SENSING CAMERA (FSC)
• Before performing the troubleshooting diagnostic procedure this time, verify if the forward sensing camera (FSC) was replaced.
• Was the forward sensing camera (FSC) replaced?
|
Yes
|
After re-implementing the required servicing when replacing the forward sensing camera (FSC) in accordance with forward sensing camera (FSC) removal/installation, perform the repair completion verification.
|
|
No
|
Go to the next step.

|
VERIFY IF MALFUNCTION IS CAUSED BY BODY CONTROL MODULE (BCM) CONFIGURATION ERROR
• Switch the ignition OFF and wait for 30 s or more.
• Switch the ignition ON (engine off or on) and wait for 30 s or more.
• Clear the DTC recorded in the memory.
(See CLEARING DTC.)
• Perform the DTC inspection for the vehicle control module (VCM).
(See DTC INSPECTION.)
• Is the same Pending DTC present?
|
Yes
|
Go to the next step.
|
|
No
|
Go to repair completion verification 2.
|

|
5
|
VERIFY BODY CONTROL MODULE (BCM) CONFIGURATION-RELATED DTCs
• Clear the DTC recorded in the memory.
(See CLEARING DTC.)
• Perform the DTC inspection for the body control module (BCM).
(See DTC INSPECTION.)
• Is a configuration related DTC displayed?
|
Yes
|
Repair the malfunctioning location according to the applicable DTC troubleshooting.
|
|
No
|
Go to the next step.
|
||
|
6
|
RESET BODY CONTROL MODULE (BCM) CONFIGURATION DATA
• Using the M-MDS, perform the body control module (BCM) configuration.
(See CONFIGURATION.)
• Clear the DTC recorded in the memory.
(See CLEARING DTC.)
• Perform the DTC inspection for the vehicle control module (VCM).
(See DTC INSPECTION.)
• Is the same Pending DTC present?
|
Yes
|
Replace the forward sensing camera (FSC) and perform the repair completion verification.
|
|
No
|
Go to repair completion verification 2.

|
Repair completion verification 1
|
VERIFY THAT VEHICLE IS REPAIRED
• Install/connect the part removed/disconnected during the troubleshooting procedure.
• Clear the DTC recorded in the memory.
(See CLEARING DTC.)
• Perform the DTC inspection for the vehicle control module (VCM).
(See DTC INSPECTION.)
• Is the same Pending DTC present?
|
Yes
|
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
If the CAN communication is normal, perform the diagnosis from Step 1.
• If the malfunction recurs, replace the body control module (BCM), then go to the next step.
|
|
No
|
Go to the next step.
