DESCRIPTION The navigation receiver assembly receives a reverse signal from the park/neutral position switch assembly. WIRING DIAGRAM
 CAUTION / NOTICE / HINT
NOTICE: Inspect the fuses for circuits related to this system before performing the following procedure. PROCEDURE
| 1. |
CHECK VEHICLE SIGNAL (OPERATION CHECK) |
| (a) Enter the "Function Check/Setting I" mode and select "Vehicle Signal" (See page
 ). | |
(b) Check that the display changes between ON and OFF according to the shift lever position.
OK: |
Shift Lever Position | Display | |
R | ON | |
Except R | OFF |
HINT: This
display is updated once per second. As a result, it is normal for the
display to lag behind the actual shift lever position.
| OK |
