PROCEDURE


  1. CHECK VEHICLE SIGNAL (OPERATION CHECK)


    1. A01WWE2

      Enter the "Vehicle Signal Check Mode" screen. [Refer to check Vehicle Signal in Operation Check Click here.]

    2. 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

      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 position.

  3. CHECK HARNESS AND CONNECTOR (MULTI-MEDIA MODULE RECEIVER ASSEMBLY - PARK/NEUTRAL POSITION SWITCH ASSEMBLY)


    1. Disconnect the F76 multi-media module receiver assembly connector.

    2. Disconnect the C19 park/neutral position switch assembly connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      for AB60F:
      Tester Connection Condition Specified Condition
      F76-57 (REV) - C19-2 (RL) Always Below 1 Ω
      F76-57 (REV) - Body ground Always 10 kΩ or higher
      for AB80F:
      Tester Connection Condition Specified Condition
      F76-57 (REV) - C19-1 (RL) Always Below 1 Ω
      F76-57 (REV) - Body ground Always 10 kΩ or higher

    NG
