3. Check the following terminals and connectors for damage, bend and loose connection (unit side and con-

nector side).

-

Around view monitor control unit

-

Harness connector B30

-

Harness connector M13

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1. Disconnect the connector of around view monitor control unit.

2. Check the resistance between the around view monitor control unit harness connector terminals.

Is the measurement value within the specification?

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 

AV-215,

"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-248, "Removal and Installa-

tion"

.

YES (Past error)>>Error was detected in the around view monitor control unit branch line.
