• Is the generator normal?

Yes

Go to the next step.

No

Replace the generator, then go to the next step.

(See GENERATOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

4

• 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 wait for 6.5 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

Repeat the inspection from Step 1.

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