* The Data List values of the brake actuator assembly are used for this inspection. Therefore, make sure to perform the inspection after confirming that no DTCs are output from the brake control system.
* If the tire size or tire inflation pressure is not within the specified range, or the tires are excessively worn, the speedometer indication error will increase. Therefore, make sure to perform the inspection after checking that the tire size, tire inflation pressure and tire wear are in the specified range.
