Keyless Entry Control Module (PEPS)
WARNING: This page is about a different car, the 2010 Buick LaCrosse. However, it is still accessible from the selected car via links, so may be relevant.
The Keyless Entry Control Module (PEPS) is a multi-function module which performs the following passive keyless entry functions:
- Transmitting vehicle antennas for passive keyless entry functions
- Backup control for the ECM accessory wakeup and the run/crank relay
- If equipped, acts as the low side driver for the electronic steering column lock
- Receiver of the door handle switch inputs and the lock sensor inputs and door open switch (not the door ajar switch)
- Driver for the unlatch motors - happens when the BCM unlatch enable signal is active and when the appropriate door handle is pulled
- Start/stop button/switch is an input to the PEPS
