Diagnosis Procedure

INFOID:0000000010477985

Regarding Wiring Diagram information, refer to 

SN-16, "Wiring Diagram"

.

1.

CHECK REAR SONAR CENTER SENSOR RH SIGNAL CIRCUIT CONTINUITY

1.

Turn ignition switch OFF.

2.

Disconnect sonar control unit connector and rear sonar center sensor RH connector.

NO

>> Repair or replace harness or connectors.

2.

CHECK REAR SONAR CENTER SENSOR RH SIGNAL CIRCUIT SHORT TO BATTERY

1.

Turn ignition switch ON.

2.

Check voltage between sonar control unit connector M59 and ground.

Is the inspection result normal?

YES

>> Replace rear sonar center sensor RH. Refer to 

SN-49, "REAR SENSOR : Removal and Installa-

tion - Rear Sonar Sensors"

.

NO

>> Repair or replace harness or connectors.
