YES

>> GO TO 3.

NO

>> Replace the main harness.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the sonar control unit. Refer to

SN-32, "Diagnosis Proce-

dure"

.

Is the inspection result normal?

YES (Present error)>>Replace the sonar control unit. Refer to

SN-34, "Removal and Installation"

.

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

NO

>> Repair the power supply and the ground circuit.
