CHECK FOR DTC

(a) Clear the DTCs.

Chassis > Panoramic View Monitor > Clear DTCs

(b) Check for DTCs.

Chassis > Panoramic View Monitor > Trouble Codes

OK:

DTC C1614 is not output.

HINT:

  • If DTC C1614 is output, perform the procedure to allow the television camera controller to store the vehicle information again.
  • If DTC C1614 is still output after performing the procedure to make the television camera controller store the vehicle information 3 times, replace the television camera controller.
  • If DTC C1614 is output frequently, replace the television camera controller even though the DTC is not output when rechecking for DTCs.
OK
