YES
>> GO TO 3.
NO
>> Repair the around view monitor control unit branch line.
3.
CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the around view monitor control unit. Refer to
"AROUND VIEW MONITOR CONTROL UNIT : Diagnosis Procedure"
.
Is the inspection result normal?
YES (Present error)>>Replace the around view monitor control unit. Refer to
AV-502, "Removal and Installa-
.
YES (Past error)>>Error was detected in the around view monitor control unit branch line.
NO
>> Repair the power supply and the ground circuit.
