Module Controlled Functions

The vehicle security module (VSM) is the only multifunction electronic module on this vehicle.

The VSM controls multiple vehicle systems including:

• Locking and unlocking all of the doors
• Panic alarm function (horn sounding and parking lamps flashing intermittently in regular intervals)
• Single horn chirp confirmation when the lock button is pressed on the remote keyless entry (RKE) transmitter twice within 3 seconds and all of the doors are closed, double horn chirp confirmation if one or more doors are open
• Single flash of the parking lamps when the lock button is pressed on the RKE transmitter with all of the doors closed. There is no parking lamp flash if the RKE transmitter LOCK button is pressed and one or more doors are ajar.
• Requests the instrument cluster (IC) to turn on the interior lamps when the doors are unlocked using a RKE transmitter
• Tire pressure monitoring system (TPMS)

The VSM also monitors the door ajar signals using the controller area network (CAN) to determine if a single or double horn chirp confirmation is necessary when locking the doors using the RKE transmitter. Also, if all of the doors are closed and the doors are locked using the RKE transmitter, the VSM will send a signal to the IC to turn off the interior lamps. If one or more doors are detected open by the door ajar switches, the VSM will not send a signal to the IC to turn off the interior lamps.
