The remote transmitter come in packs of two. Each
transmitter is associated with a series of numbers, which are
shown on a label located on the transmitter packaging.
These numbers are required to program the transmitter to a
vehicle.

Workshop Manual
Integrated Passive Anti-Theft
System (IPATS)
Description
IPATS (immobilisation system) is responsible for enabling /
disabling engine functionality. The system is totally passive
and requires no extra intervention from the user.
To prevent the engine from starting the IPATS disables the
fuel pumps, injectors, and the crank circuit.
Disarming IPATS
When the ignition key is located in the ignition barrel and
turned to position 'II', the key is validated. If successful,
subsequent requests for crank and engine start will be
allowed. If the key validation fails, then engine starting will
be prevented.
Arming IPATS
To arm the system the user simply removes the ignition key.
IPATS LED
An IPATS LED is located in the DIM to display the
immobilisation status and DTC's using flash codes.
Normal behaviour following a successful key read is for the
LED to illuminate for three seconds and then to extinguish.
If the self-test detects any problem with IPATS when the
ignition is turned on, the IPATS LED will flash at 4Hz for 1
minute. The IPATS LED will then flash one of the following
codes:
