Inspection

Results

Action

1
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 procedure.
No
Go to the next step.
2
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).
•  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.
3
INSPECT FORWARD SENSING CAMERA (FSC) FOR MALFUNCTION
•  Perform the DTC inspection for the forward sensing camera (FSC).
•  Is a DTC displayed?
Yes
