If the result of the road test is within the specified range, it is possible that this DTC was stored due to a particular situation such as wheelspin, brake drag or wheel lockup.

When a DTC is stored during operation of ABS or TRC, the system also stores vehicle control history that can be guessed the vehicle conditions.
