Step

Inspection

Action

1

• Using the M-MDS, perform the forward sensing camera (FSC) configuration (using As-Built data).

  (See FORWARD SENSING CAMERA (FSC) CONFIGURATION (USING AS-BUILT DATA).)

• 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

Using the M-MDS, perform the forward sensing camera (FSC) configuration (using As-Built data) again, then go to the next step.

(See FORWARD SENSING CAMERA (FSC) CONFIGURATION (USING AS-BUILT DATA).)

No

Go to Step 3.

2

• 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

Repeat the inspection from Step 1.

• If the malfunction recurs, replace the forward sensing camera (FSC).

  (See FORWARD SENSING CAMERA (FSC) REMOVAL/INSTALLATION.)

Go to the next step.

No

Go to the next step.

3
