Speedometer Check

CAUTION: Since the diagnosis code may be stored in the ABS-ECU when checking the speedometer with speedometer tester, erase the diagnosis code.
CAUTION: Do not accelerate or decelerate suddenly during servicing work.
  1. Adjust the pressure of tires to the specified level (Refer to ON-VEHICLE SERVICE ).
  2. Set the vehicle onto a speedometer tester and use wheel chocks to hold the rear wheels.

  5. Check if the speedometer indicator range is within the standard values.
