Diagnostic Procedure

Step	Inspection		Action
1	VERIFY IF FORWARD SENSING CAMERA (FSC) TEMPERATURE WAS TEMPORARILY HIGH • Leave the vehicle in a cool location. • Clear the DTC for the forward sensing camera (FSC) using the M-MDS. (See CLEARING DTC [FORWARD SENSING CAMERA (FSC)].) • Switch the ignition ON (engine off or on) and drive the vehicle at 10 km/h or more for 5 s or more. • Retrieve the forward sensing camera (FSC) DTCs using the M-MDS. (See DTC INSPECTION [FORWARD SENSING CAMERA (FSC)].) • Is the same DTC displayed?	Yes	Go to the next step.
1		No	Go to Step 3.
2	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Clear the DTC for the forward sensing camera (FSC) using the M-MDS. (See CLEARING DTC [FORWARD SENSING CAMERA (FSC)].) • Switch the ignition ON (engine off or on) and drive the vehicle at 10 km/h or more for 5 s or more. • 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.)
2		No	Verify the forward sensing camera (FSC) system operation record using the M-MDS. • Explain the conditions to the customer referring to the forward sensing camera (FSC) system operation record. Go to the next step.
3	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)].)
3		No	DTC troubleshooting completed.
