Speedometer Malfunction [08/2015 - ]: Procedure

  1. CHECK CAN COMMUNICATION 
    1. Check for DTCs (Refer to DTC CHECK / CLEAR [08/2015 - ] ).
      RESULT

      Result Proceed to
      CAN communication DTC is not output A
      CAN communication DTC is output B

    Result: 

    Go to CAN COMMUNICATION SYSTEM 

    (Refer to HOW TO PROCEED WITH TROUBLESHOOTING [08/2015 - ] )

    Result: 

    See step  2

  2. CHECK SFI SYSTEM (VEHICLE SPEED) 
    1. Check for DTCs (Refer to DTC CHECK / CLEAR [08/2015 - ] ).

    Result: 

    NG 

    Go to DIAGNOSTIC TROUBLE CODE CHART 

    (Refer to DIAGNOSTIC TROUBLE CODE CHART [08/2015 - 08/2016] , or refer to DIAGNOSTIC TROUBLE CODE CHART [08/2016 - 08/2017] , or refer to DIAGNOSTIC TROUBLE CODE CHART [08/2017 - 08/2018] , or refer to DIAGNOSTIC TROUBLE CODE CHART [08/2018 - 08/2019] , or refer to DIAGNOSTIC TROUBLE CODE CHART [08/2019 - ] )

    Result: 

    OK 

    See step  3

  3. PERFORM ACTIVE TEST USING TECHSTREAM (SPEEDOMETER) 
    1. Operate the Techstream according to the display and select Active Test (Refer to DATA LIST / ACTIVE TEST [08/2015 - ] ).
      COMBINATION METER

      Tester Display Test Part Control Range Diagnostic Note
      Speed Meter Operation Speedometer 0, 40, 80, 120, 160, 200, 240 or 280 Acceptable range (mph or km/h): [Control range → Speedometer display]
      for mph 
      • 40 → 39.5 to 42.5
      • 80 → 80.5 to 84.5
      • 120 → 120.5 to 126

      for km/h 
      • 40 → 38 to 42
      • 80 → 78 to 84
      • 120 → 119 to 125
      • 160 → 159 to 167
      • 200 → 199 to 209
      • 240 → 239 to 251

      Perform the test with the vehicle stopped and engine idling.

      HINT: 

      • Make sure that the vehicle is stopped and the engine is idling. The doors will be locked automatically when performing the speedometer Active Test. This is a normal function.
      • The displayed value has the same units (km/h, mph) as the main scale of the vehicle speedometer.
      • The needle position should be within the acceptable tolerance.

        OK

        Needle indication is normal.

    Result: 

    NG 

    REPLACE COMBINATION METER ASSEMBLY 

    (Refer to REMOVAL [08/2015 - ] )

    Result: 

    OK 

    See step  4

  4. READ VALUE USING TECHSTREAM (VEHICLE SPEED) 
    1. Operate the Techstream according to the display and select Data List (Refer to DATA LIST / ACTIVE TEST [08/2015 - ] ).
      COMBINATION METER

      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Vehicle Speed meter Vehicle speed/Min.: 0 (0), Max.: 255 (158) Almost same as actual speed (when driving) Unit: km/h (mph)

      OK

      Vehicle speed displayed on the Techstream is almost the same as actual vehicle speed measured using speedometer tester (calibrated chassis dynamometer).

    Result: 

    OK 

    REPLACE COMBINATION METER ASSEMBLY 

    (Refer to REMOVAL [08/2015 - ] )

    Result: 

    NG 

    See step  5

  5. READ VALUE USING TECHSTREAM (WHEEL SPEED SENSOR) 
    1. Operate the Techstream according to the display and select Data List (Refer to DATA LIST / ACTIVE TEST [08/2015 - ] ).
      ABS/VSC/TRAC

      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      FR Wheel Speed Wheel speed sensor FR reading/Min.: 0 (0), Max.: 326 (202) Actual wheel speed A similar speed is indicated on the speedometer.
      FL Wheel Speed Wheel speed sensor FL reading/Min.: 0 (0), Max.: 326 (202) Actual wheel speed A similar speed is indicated on the speedometer.
      RR Wheel Speed Wheel speed sensor RR reading/Min.: 0 (0), Max.: 326 (202) Actual wheel speed A similar speed is indicated on the speedometer.
      RL Wheel Speed Wheel speed sensor RL reading/Min.: 0 (0), Max.: 326 (202) Actual wheel speed A similar speed is indicated on the speedometer.

      OK

      Vehicle speed displayed on the Techstream is almost the same as actual vehicle speed measured using speedometer tester (calibrated chassis dynamometer).

    Result: 

    OK 

    REPLACE COMBINATION METER ASSEMBLY 

    (Refer to REMOVAL [08/2015 - ] )

    Result: 

    NG 

    REPLACE HYDRAULIC BRAKE BOOSTER ASSEMBLY 

    (Refer to REMOVAL [08/2015 - ] )
