GENERAL OPERATION

Immobiliser Receiver - (Type 1 & 2)

The receiver is an electrical coil embedded within the ignition switch

bezel. Power is provided by the immobiliser control unit (Type 1) or

the ECU (Type 2) and when a programmed key is inserted into the

ignition switch the transponder is energised by electromagnetic

induction. Once energised the transponder transmits its ID code to

the receiver, which is then transmitted to the control unit (Type 1) or

the ECM (Type 2).

Note: The immobiliser receiver does not need re-

programming when replaced.

Immobiliser Control Unit - (Type 1)

Location

: Below the dashboard on the left side of the steering col-

umn.

Once the transponder ID code is received from the immobiliser re-

ceiver, it is checked against codes stored within its memory

(maximum of 5).

Code Accepted: Power provided to the starter cut relay.

A unique serial code is transmitted to the

ECU

Code Not Accepted: No Power is provided to the starter cut relay

Unique serial code is not transmitted to the

ECU.

Immobiliser Control Unit-Receiver - (Type 3 & 4)

These types of system use a combined immobiliser control unit-

receiver, which is located around the ignition switch. When a pro-

grammed key is inserted into the ignition switch the transponder is

energised by electromagnetic induction and transmits its ID code to

the control unit-receiver, where it is checked against codes stored

within its memory (maximum of 5).

Code Accepted: A unique serial code is transmitted to the ECU.

Code Not Accepted: Unique serial code is not transmitted to the ECU.
