There are two types of immobilizer functions available on the Body Control Module (BCM). The first is a "SMARTRA (SMART
TRansponder Antenna)"type and the second is a "stand alone" type that will emulate the system known as the "SCE
immobilizer". The hardware to support both types of immobilizer systems in the BCM is identical. The selection of immobilizer
type withinthe BCM is effected by setting the appropriate EEPROM byte.
All communications between the BCM and the ECM (Engine Control Module) for the purposes of immobilization will be over
the W line.
The diagnostics communication for the SMARTRA system will be performed by communicating with the ECM on it's K line.
The ECM will then perform diagnosticson the BCM via the W line.
At the time of Transponder validation, the BCM devotes 100% processing power to the validation process in order to respond
in the required time.During transponder validation, other BCM functions may be influenced.

DESCRIPTION

1. SMARTRA type immobilizer

The "SMARTRA" type immobilizer system is applied to the 2.0

β

engine.

The immobilizer system consists of a passive challenge-response (mutual authentication) transponder inside the key head,
a stand alone antenna, the BCM unit and the ECM. The BCM unit shall emulate the original SMARTRA immobilizer as
closely as possible. In this document, the BCM emulating the originalSMARTRA shall just be known as SMARTRA.
In the SMARTRA system, the immobilizer is contained within the ECM. The BCM shall provide the low-level routines and
hardware necessary to communicatewith the transponder.

2. Stand alone type immobilizer

The "Stand alone" type immobilizer system is applied to the 2.7

δ

engine.

The immobilizer system consists of a passive challenge-response (mutual authentication) transponder inside the key head,
a stand alone antenna, the BCM unit and the ECM. The BCM unit shall emulate the original SCE type immobilizerto ECM
protocol as closely as possible.
In the Stand alone immobilizer system, the immobilizer is contained within the BCM. The ECM shall request the BCM for
permission to start the vehicle. The BCM shall perform the immobilisation functions and reply "start"or no start" permission
to the ECM.
