DTC U0415:68 [FORWARD SENSING CAMERA (FSC)]

id1502a3011100


Forward Sensing Camera (FSC) Type A (VIN Serial No. 100001—)

Description

Error signal received from DSC HU/CM
Detection condition
•  Forward sensing camera (FSC) receives the error signal from the DSC HU/CM for 5 s or more.
Fail-safe
•  Inhibits the lane departure warning system (LDWS).
Possible cause
•  DTCs are stored in the DSC HU/CM.
?  DSC HU/CM malfunction
•  Forward sensing camera (FSC) malfunction
Note
•  When running the vehicle on a chassis dynamometer even though the vehicle speed is high, DTCs may be detected because the amount of change in the images at the front of the vehicle shot by the Forward Sensing Camera (FSC) is low.

Diagnostic Procedure

Step

Inspection

Action
1
VERIFY DSC HU/CM DTCs
•  Retrieve the DSC HU/CM DTCs using the M-MDS.

Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [DSC HU/CM].)
No
Go to the next step.
2
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  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
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.
3
VERIFY IF OTHER DTCs DISPLAYED
