Vehicle Security Module

WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The vehicle security module monitors the inputs and provides outputs and diagnostic information for the following systems:

The vehicle security module also provides the instrument cluster with door ajar information over the universal asynchronous receiver-transmitter (UART) based protocol (UBP) communications network in order for the instrument cluster to close the interior lamps relay, providing power to the interior lamps and the running board lamps (if equipped). If the vehicle is not equipped with a vehicle security module, the door ajar switches are hardwired to the instrument cluster. If equipped, the vehicle security module grounds the horn relay when the panic function is commanded by using the RKE transmitter.
