POWER SUPPLY AND GROUND CIRCUIT
Diagnosis Procedure (With Rear Sonar System)INFOID:0000000004173800
INSPECTION FOR POWER SUPPLY AND GROUND CIRCUIT
1.CHECK FUSES
Check for blown rear sonar system fuses.
Are any fuses blown?
YES >> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse. Refer to GI-
41, "Circuit Inspection".
NO >> GO TO 2.
2.CHECK POWER SUPPLY CIRCUIT
1. Disconnect sonar control unit connector.
2. Turn ignition switch ON.
3. Check voltage between sonar control unit connector B24 termi- nal 8 and ground.
Is there battery voltage?
YES >> GO TO 3.
NO >> Check harness for open between sonar control unit and fuse.
3.CHECK GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Check continuity between sonar control unit connector B24 ter- minal 6 and ground.
Is there continuity?
YES >> Inspection End.
NO >> Check harness ground circuit.
