SONAR SYSTEM OFF SWITCH CIRCUIT INSPECTION

Description

INFOID:0000000006159214

The sonar system can be disabled by momentarily pressing the rear sonar system OFF switch. The sonar sys-

tem OFF indicator lamp will be illuminated when the sonar system is OFF.  Enabling the sonar system will

cause the sonar system OFF indicator to go out.  The indicator will flash if a malfunction exists in the system.

Diagnosis Procedure

INFOID:0000000006159215

Regarding Wiring Diagram information, refer to 

SN-17, "Wiring Diagram"

.

1.

CHECK SONAR SYSTEM OFF SWITCH

Refer to 

SN-13, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace sonar system OFF switch.  Refer to 

IP-17, "Removal and Installation"

.

2.

CHECK SONAR SYSTEM OFF SWITCH CIRCUITS

1. Turn ignition switch OFF.

2. Disconnect sonar control unit connector and sonar system OFF switch connector.

3. Check continuity between sonar control unit harness connector

(A) and sonar system OFF switch harness connector (B).

4. Check continuity between sonar system OFF switch harness

connector and ground.

Are the inspection results normal?

YES

>> Inspection End.

NO

>> Repair harness or connector.
