If the CAN communication is normal, replace the forward sensing camera (FSC) and perform the repair completion verification. (See FORWARD SENSING CAMERA (FSC) REMOVAL/INSTALLATION .)
4		No	Perform the [ACTION FOR NON-REPEATABLE MALFUNCTIONS]. (See TROUBLESHOOTING PROCEDURE (US) .) If DTC is displayed Repeat the diagnosis from Step 1. If DTC is not displayed 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?
