To reset the computer on a 2001 Pontiac Montana Van, you can disconnect the negative battery cable for about 15 minutes to clear any stored error codes. After reconnecting the cable, turn the ignition to the "On" position without starting the engine for a few seconds. This allows the computer to reset. Finally, start the van and let it idle for a few minutes to allow the system to recalibrate.
