Reset ford ranger computer?

The Ford PCM or "power control module" is responsible for managing the key operating components of a vehicle. This includes engine and transmission functions. Occasionally an owner might want to clear codes associated with the PCM or "relearn" or reset the PCM's memory. It is possible to plan a visit to a certified dealership for this procedure because it generally involves the use of expensive diagnostic equipment and an OBDII scanner. However, if You want to try a simpler but effective approach from home, use the Ford Ranger's battery to clear up Your PCM. Disconnect the negative battery cable and wait at least 15 minutes before re-connecting. Start the car and drive at various RPM's and speeds to "relearn" the power control module. Some use this technique in conjunction with an OBDII scanner.
