Speedometer Check

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

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 DTC P1767 (P0720): OUTPUT SHAFT SPEED SENSOR SYSTEM (SHORT CIRCUIT/OPEN CIRCUIT) ).
- Combination meter (refer to INSPECTION PROCEDURE 6: SPEEDOMETER DOES NOT WORK (OTHER METERS WORK) .)
