Clearing Diagnostic Trouble Codes
WARNING: This page is about a different car, the 1995 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
After repairs have been performed, use DRB and manufacturer's instructions to clear or erase DTC from TCM memory.
NOTE:
If malfunction no longer exists after DTC is stored in TCM memory, the TCM will erase DTC after ignition has been cycled at least 50 times. DTC may be cleared by disconnecting negative battery cable for a period of time, but other vehicle control modules may also be affected.
