    Speedometer needle accuracy specification communication

    1. 1Fault

      • A customer may say the speedometer needle appears inaccurate.

    2. 2Finding the cause

      Possible causes

      • The speedometer needle is driven electrically by a stepper motor and some variation in accuracy is possible.
      • Tire size, tread life and inflation may cause some variation in the readings.

      Steps to confirm (in the document’s order)

      1. Digital readouts such as the "Digital Speedometer" on the DIC read the Vehicle Speed Sensor (VSS) directly and are much more accurate.
      2. The specification for needle accuracy is +/- 2 MPH (= 3.22 km/h) at any given speed when looking straight at the needle.

    3. 3Correction

      This Preliminary Information communication provides information to the technician about vehicles that the speedometer needle appears to be inaccurate. Dealer should advise the customer the specification for speedometer needle accuracy is +/- 2 MPH (= 3.22 km/h) at any given speed when looking straight at the needle.

      What the documents say to do
