Gm Vats Or Passkey Ii Security Bypass Module on 2040-parts.com

VATS Bypass Module All products come with instructions.

This VATS bypass module is intended for use when installing a GM engine equipped with VATS (Vehicle Anti-Theft System) into a vehicle missing the BCM (Body Control Module), when resistor type bypasses just wont work, or for use with remote starting applications involving stock vehicles equipped with VATS. Our VATS bypass will also work to bypass failing VATS systems.

This bypass module generates the 'key OK' signal normally sent from the BCM, sometimes called the VATS decoder, to the PCM/ECM when the proper key is detected. Without this signal, the fuel injectors will shut down within the first 3 seconds. Normally it costs between $150 and $300 to have this feature deleted from the PCM. By using our module you will accomplish the same function for less and you won't have to ship your PCM/ECM to have it reprogrammed.

Our module will work with:

Our module is a simple four-wire interface (power, ground, standard signal and 30Hz signal) and if installed with a detachable connector, it can be removed to enable the factory anti-theft system to protect your car over night or at the car show. You can't do that if you programmed that feature out of your PCM/ECM.

This module comes equipped with a status LED that indicates that it is functioning. LED will flash once every eight seconds when power is applied.

To connect module you will need  your car specific wiring diagram to find 'fuel enable' wire. Due to variety of cars and low item cost we do not provide car specific wiring diagram. We rely on user to do basic research. Online forums full of instructions for bypass connections.

This bypass does not remove need for starter bypass which is easily done with relay rewiring. You can find this information on the web and car forums. We do not provide instructions for starter bypass
