NAVIGATION SYSTEM (for HDD) Reverse Signal Circuit

DESCRIPTION

The navigation receiver assembly receives a reverse signal from the park/neutral position switch*1 or back-up light switch*2 and information about the navigation antenna, and then adjusts the vehicle position.

*1: for CVT

*2: for Manual Transaxle

INSPECTION PROCEDURE

Note

Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE


  1. CHECK NAVIGATION RECEIVER ASSEMBLY (DISPLAY CHECK MODE)


    1. A00DSPME02

      Enter the "Failure Check/Setting" mode and select "Vehicle Signal" Click here.

    2. Check that the display changes between ON and OFF according to the shift lever operation.

      OK
      Shift lever Position Display
      R ON
      Except R OFF

      Tech Tips

      This display is updated once per second. As a result, it is normal for the display to lag behind the actual shift lever operation.


    NG
    OK
