Codes stored within the ECU memory must be erased when repairs are completed. Erasing codes during diagnosis can help you to separate hard (consistent) faults from intermittent malfunctions. To erase stored codes, disconnect the negative battery cable, then depress the brake pedal for at least 10 seconds. After reconnecting the battery cable, check the system for any remaining or newly set codes.
