Speedometer Check
CAUTION:
- Since the DTC may be set in the ASC-ECU when checking the speedometer with speedometer tester, erase the DTC.
- Do not accelerate or decelerate suddenly during servicing work.
- Adjust the pressure of tires to the specified level (Refer to TIRE INFLATION PRESSURE CHECK ).
- Press the ASC OFF switch for 3 seconds or more to stop the ASC operation.
- Set the vehicle onto a speedometer tester and use wheel chocks to hold the rear wheels.
- To prevent front wheel lateral runout or vehicle sudden start, attach a chain or wire to the front and rear towing hooks and fix the other end of the chain or wire to the anchor plate.
- Check that the speedometer indicating range is within the standard value and the needle fluctuation is within the limit value.
Standard value:
Standard indication {mph (km/h)} Indication tolerance {mph (km/h)} 25 (40) 23.5 - 26.5 (40.5 - 44.5) 50 (80) 48.5 - 51.5 (81.5 - 86.5) 75 (120) 73.5 - 76.5 (122.5 - 128.5) 100 (160) 98.5 - 102.5 (162.5 - 169.5) - 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 ASC and the combination meter. Check the following items.
- ASC (Refer to DIAGNOSIS ).
- Combination meter (refer to DIAGNOSTIC TROUBLE CODE CHART ).
