6.3.￿Overview￿of￿functions
There￿is￿no￿insertion￿slot￿installed￿in￿the￿I01.￿The￿vehicle￿can￿already￿be￿started￿without￿a￿key￿as
standard.￿This￿function￿is￿called￿"Passive￿Go"￿(drive￿authorization).￿However,￿to￿gain￿access￿to￿the
vehicle,￿it￿is￿still￿necessary￿to￿actuate￿the￿ID￿transmitter.
The￿following￿locking￿and￿security￿functions￿are￿integrated￿in￿the￿I01￿in￿the￿Body￿Domain￿Controller:
• Comfort￿Access
The￿optional￿equipment￿Comfort￿Access￿contains￿the￿"Comfort￿Entry"￿and￿"Comfort￿Exit"
functions.￿The￿"Passive￿Go"￿function￿comes￿as￿standard.
• Central￿locking￿system
• Power￿window￿regulators
• Sliding/tilting￿sunroof
• Terminal￿control
• Electronic￿immobilizer.
The￿locking￿and￿security￿functions￿of￿the￿I01￿are￿based￿on￿the￿CAS￿functions￿in￿the￿F01￿and￿are
described￿in￿the￿"Car￿Access￿System￿F01/F02"￿training￿material.
With￿regard￿to￿start￿enable￿by￿the￿electronic￿immobilizer￿(also￿called￿Challenge￿Response),￿some
changes￿have￿been￿made￿from￿the￿F01.￿What￿is￿new￿is￿the￿omission￿of￿the￿CAS￿bus,￿because￿PT-CAN
and￿FlexRay￿already￿provide￿redundancy￿of￿data￿transfer￿between￿BDC￿and￿EDME.
In￿addition￿to￿the￿transmission￿release￿in￿the￿control￿unit￿GWS￿in￿the￿I01￿there￿is￿also￿a￿release￿of
the￿steering￿via￿the￿Electronic￿Power￿Steering.￿The￿emergency-start￿function￿by￿stopping￿the￿ID
transmitter￿at￿the￿ring￿aerial￿is￿already￿known￿from￿the￿F01.
6.4.￿Central￿locking￿system
The￿function￿of￿the￿central￿locking￿system￿of￿the￿I01￿is￿based￿on￿that￿of￿current￿BMW￿models.￿With￿the
introduction￿of￿the￿BDC￿all￿relevant￿functions￿for￿the￿central￿locking￿system￿are￿handled￿by￿one￿control
unit.￿The￿function￿is￿as￿follows:
The￿radio￿signal￿from￿the￿ID￿transmitter￿is￿received￿by￿the￿remote￿control￿receiver.
The￿signal￿causes￿the￿BDC￿to￿activate￿the￿central￿locking￿system￿and￿the￿interior￿lighting.
