NAVIGATION UNIT CONNECTOR A (17P) ILL (GRY)NOTE: Check the vehicle battery condition first.
 Check the connectors for poor connections or loose terminals.
1. Turn the ignition switch to ON (II).
2. Turn the combination lighting switch to the parking light position.
3. Check the illumination of the navigation unit buttons.
Intermittent problem: the navigation unit is
OK at this time. Check for loose or poor
connections at navigation unit connector A (17P).
Go to step 4.
4. Check the illumination of several other buttons not related to the navigation system.
Go to step 5.
Troubleshoot the interior lights. Start by
checking the No. 14 (7.5 A) fuse in the under-dash
fuse/relay box. If the fuse is OK, check for an open
in the wire between the under-dash fuse/relay box
and the navigation unit.
5. Turn the ignition switch to LOCK (0).
6. Disconnect navigation unit connector A (17P). NOTE: Eject all the discs before removing the navigation unit to prevent damaging the CD player’s load
mechanism.
 Remove the PC card before removing the navigation unit.
7. Disconnect gauge control module (tach) 36P connector. 8. Check for continuity between navigation unit
connector A (17P) terminal No. 1 and gauge control
module (tach) 36P connector terminal No. 14.
Go to step 9.
Repair open in the wire between the gauge
control module and the navigation unit.
9. Turn the ignition switch to ON (II).
10. With the headlight switch still on, measure the voltage between navigation unit connector A (17P)
terminal No. 10 and body ground.
Check the connections at navigation unit
connector A (17P). If all connections are OK, replace
the navigation unit (see page 23-155).
Repair open in the wire between the under-
dash fuse/relay box and the navigation unit.
