1.1
Scope of SK IBU System
IBU(Integrated Body control unit) System(-SMK) integrate BCM in one ECU
1.1.1 IBU(-SMK) system offer following feature
LF
communication
immobilizer backup solution integrated into IBU
communication to the engine management system via a single line interface
communication to the ESCL via a single line interface
block of the steering column by the ESCL device
communication to the engine management system via a single line interface
communication to the ESCL via a single line interface
block of the steering column by the ESCL device
1.1.2 BCM functions offer following feature
BCM functions directly or indirectrly control Lamps, Indicators, Rear curtain, Steering
wheel heat and relay
1.2
short description of the SYSTEM
If insert the Immobilizer including trasponder to ignition switch and then power enter the
IBU(-SMK)
After Receive the frequency of key, ECU decide the own’s key and if same code ,starting
a engine.

1.2.1
General Definition of IBU(-SMK)
IBU(-SMK) has a immobilizer function which enable the start up When Folding key
approaching the Lock-body.
1.2.2 Wireless
Communication
the Electromagnetic waves used for communication between Foldingkey and car.
Therefore car and Folding key include the tramsmitter, receiver and Immobilizer Antenna.
Therefore car and Folding key include the tramsmitter, receiver and Immobilizer Antenna.
1.2.3 concept
Description
magnetic field with a frequency of 125 kHz and ASK modulation is used
Technical aspects of 125 kHz – magnetic field:
Technical aspects of 125 kHz – magnetic field:
high
penetration,
less sensitive for detuning compared to higher frequency.
For the down-link from the SMART KEY FOB to the vehicle, the standard radio frequency
(RF) is used (similar to the classic remote control functions) with FSK modulation.
