2.3 System Description
The Body Control Module (BCM) NewCMF1 is an integrated transmitter-
receiver (base station) in the vehicle that interfaces with the Remote Keyless Entry
(RKE) FOBIK using RF and LF. The BCM NewCMF1 contains the controlling logic for
the Passive Entry (pase) Keyless Go (PEKG) and Immobilizer (Immo).
The BCM New CMF1 communicates on the CAN vehicle communication bus.
The BCM New CMF1 also interfaces with the vehicle’s door handles, trunk/Liftgate
(as equipped) and multiple LF antennae for purposes of providing PEKG
functionality.

4 Functions Variants
a. TPMS
(Tire-Pressure Monitoring System)
i. System Explanation
To control the pressure of vehicles wheels, the pressure captor (certificate done) transmit
information to the BCM in RF. The BCM decode the signal (with RF Receiver) and transmit
data on CSPI bus No LF transmission
b. RKE
(Remote Keyless Entry System)
i. System Explanation
To lock and unlock the vehicle at distance a function is implemented in the system. The
FOBIK transmit to the receiver an order. That it transmits on the CAN bus allows to achieve
function No LF transmission

c. PASE
(Passive Entry)
i. System Explanation
The system works by having a series of LF
(low frequency 125 kHz) transmitting
antennae both inside and outside the
vehicle. The external antennae are located in
the door handles. When the vehicle is
triggered, either by pulling the handle or
touching the handle, an LF signal is
transmitted from the antennas to the key.
The key becomes activated if it is sufficiently
close and it transmits its ID back to the
vehicle via RF to a receiver located in the
vehicle. If the key has the correct ID, the
PASE module unlocks the vehicle.
d. PASE
i. System Explanation
When the battery of Fobik is totally discharged, the BCM contains a function
which pilots the antenna Room’s 1. This antenna allows communicating at short
distance with LF stage present on Fobik and to supply by field the Fobik to create a
Carrier Wave signal. The LF coil which is used to communicate and authenticate
Fobiks during Limp Home mode (125Khz).
