Diagnostic Procedure

Step	Inspection		Action
1	VERIFY IF MALFUNCTIONING LOCATION IS FORWARD SENSING CAMERA (FSC) DEPENDING ON REPEATABILITY Clear the DTC for the forward sensing camera (FSC) using the M-MDS. (See CLEARING DTC [FORWARD SENSING CAMERA (FSC)].) Retrieve the forward sensing camera (FSC) DTCs using the M-MDS. (See DTC INSPECTION [FORWARD SENSING CAMERA (FSC)].) Is the same DTC displayed?	Yes	Replace the forward sensing camera (FSC), then go to the next step. (See FORWARD SENSING CAMERA (FSC) REMOVAL/INSTALLATION.)
		No	Go to the next step.
2	VERIFY IF OTHER DTCs DISPLAYED Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [FORWARD SENSING CAMERA (FSC)].)
		No	DTC troubleshooting completed.
