Speedometer Check

SPEEDOMETER CHECK

1. Adjust the pressure of tires to the specified level (Refer to Tire and Wheel, On-vehicle Service).
2. Where applicable, ensure that the TPMS warning light is not illuminating or flashing.

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.

CAUTION: Set a free-roller on the rear tire for AWD.




3. For FWD vehicles, set the vehicle onto a speedometer tester and use wheel chocks to hold the rear wheels.




4. For AWD vehicles, set the vehicle onto a speedometer tester and place the rear wheels on a free roller.




5. To prevent the front wheel from moving from side to side, attach tension bars to the tie-down hook, and secure both ends to anchor plates.
6. To prevent the vehicle from moving, attach a chain or wire to the rear retraction hook, and make sure the end of the chain or wire is secured.




7. Check if the speedometer indicator range is within the standard values.
8. If not within the standard value, check the tire size. If an incorrect size of tire is used, replace it and check again. If the tire size is correct, a defect may be present in components and circuit between the output shaft speed sensor and the combination meter. Check the following items.
- output shaft speed sensor (refer to Automatic Transaxle Diagnosis).
- combination meter.
