Diagnostic Procedure

Step

Inspection

Action
1
PERFORM DTC INSPECTION AND VERIFY FORWARD SENSING CAMERA (FSC) MALFUNCTION
•  Clear the DTC for the forward sensing camera (FSC) using the M-MDS.
•  Retrieve the forward sensing camera (FSC) DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the forward sensing camera (FSC).
Go to the next step.
No
Go to the next step.
2
VERIFY IF OTHER DTCs DISPLAYED
