nector terminal 51.

4.

Check continuity between display unit harness connector terminal 4 and ground.

Is inspection result OK?

YES

>> GO TO 2.

NO

>> Repair harness or connector.

2.

CHECK HORIZONTAL SYNCHRONIZING (HP) SIGNAL

1.

Connect display unit connector and NAVI control unit connector.

2.

Turn ignition switch ON.

3.

Check signal between display unit harness connector terminal 4 and ground.

Is inspection result OK?

YES

>> Replace NAVI control unit.

NO

>> Replace display unit.
