Keyless Entry Control Module (PEPS)

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
