There are 2 different procedures used to reset PCMs; depending on whether the vehicle has the older OBD1 emission control system; or whether it has the OBDII system. With the older OBD1 system; the PCM could be reset by disconnecting the battery for several minutes. But the later model OBDII system cannot be reset that way. It requires connecting an OBDII compatible code scanner to the vehicle, and using the scanner to reset the PCM. --------------------------------------------------------------------------------------
