Inspection Procedure

  1. CHECK VEHICLE SPEED SIGNAL (DISPLAY CHECK MODE) 
    1. Enter the "Display Check" mode and select "Vehicle Signal Check" (See OPERATION CHECK  ).
    2. Check that the vehicle speed on the display changes according to the actual vehicle speed.

      OK: The display changes according to the actual vehicle speed. 

      HINT:

      This display is updated once per second. As a result, it is normal for the display to lag behind the actual change in the vehicle speed.

    OK: REPLACE NAVIGATION ECU  (See NAVIGATION ECU  )

  4. CHECK COMBINATION METER (SPEEDOMETER OPERATION) 
    1. Drive the vehicle and check if the function of the speedometer in the combination meter is normal.

      OK: Actual vehicle speed and the speed indicated on the speedometer are the same. 

      HINT:

      The vehicle speed sensor is functioning normally when the indication on the speedometer is normal.

      NG: GO TO METER/GAUGE SYSTEM  (See HOW TO PROCEED WITH TROUBLESHOOTING )

      OK: Go to Next Step 

  5. CHECK HARNESS AND CONNECTOR (MULTI-DISPLAY - COMBINATION METER) 
    1. Disconnect the F28 display connector.
    2. Disconnect the E7 meter connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance 

    RESISTANCE REFERENCE

    Tester Connection Condition Specified Condition
    F28-14 (SPD) - E7-4 (+S) Always Below 1 Ω
    F28-14 (SPD) - Body ground Always 10 kΩ or higher

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
