Question

Quizplus · Accepted Answer

Permanent DTCs can only be cleared from the PCM by driving the vehicle after the repair and allowing the system to run its tests. Simply disconnecting the battery or pushing a DTC reset button will not clear the permanent DTCs. A generic scan tool may be used to clear the fault codes, but it can only clear the soft codes, not permanent DTCs. Therefore, the best choice is D.
