Vehicle position does not move on the map

Before testing, inspect the No.6 (15A) fuse in the driver's under-dash fuse/relay box.

1. Start the engine.
2. Perform the Car Status Test in the Picture Diagnosis Test menu.

Is there vehicle speed pulse signal?

YES - Replace the navigation unit.

NO - Go to step 3.

3. Turn the ignition switch OFF.
4. Raise the front of the vehicle, and make sure it is securely supported.
5. Put the vehicle in neutral with the ignition switch ON (II).




6. Measure the voltage between body ground and navigation unit connector C (8P) terminal No.6.
7. Slowly rotate one wheel with the other wheel blocked.

Does voltage pulse from 0 to approx. 5 V?

YES - Replace the navigation unit.

NO - Go to step 8.

8. Turn the ignition switch OFF.




9. Disconnect the 3P connector from the vehicle speed pulse (VSP) sensor (A).
10. Connect the test harness only to the engine wire harness.
11. Connect the RED test harness clip (B) to the positive prove of an ohmmeter. Cover the white (C) and green (D) test harness with protective tape (E).
12. Check for continuity between the RED test harness clip and body ground.

Is there continuity?

YES - Go to step 13.

NO - Repair open in the BLK wire between the VSP and G101.




13. Connect the WHT test harness clip (A) to the positive probe of a voltmeter, and connect the RED test harness clip (B) to the negative probe.
14. Turn the ignition switch ON (II).

Is there battery voltage?

YES - Go to step 15.

NO - Repair open in the BLK/YEL wire between the VSP and the driver's under-dash fuse/relay box.

15. Turn the ignition switch OFF.
16. Disconnect the navigation unit connector C (8P) from the navigation unit.
17. Disconnect the WHT and RED test harness clips.
18. Connect the GRN test harness clip (A) to the positive probe of the ohmmeter.




19. Check for continuity between the GRN test harness clip and body ground.

Is there continuity?

YES - Repair short the BLU/WHT wire between the VSP and the navigation unit.

NO - Go to step 20.

20. Reconnect the navigation unit connector C (8P).
21. Turn the ignition switch ON (II).




22. Connect the GRN test harness clip (A) to the positive probe of a voltmeter, and connect the RED test harness clip (B) to negative probe.

Is there 5 V?

YES - Replace the VSP.

NO - Repair open in the BLU/WHT wire between the VSP and the navigation unit.
