Active Anti-Theft System (19.01)
Electronic Features (19.00)19-1-4 Workshop ManualIssue 5, January 2010
Remote Transmitter
The security system allows up to eight remote transmitters to
be used for controlling the system functions.
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.
Key Learning Operations
Using WDS.
1. Select ‘Set up and Configuration’.
2. Select either:
• Transmitter add
• Transmitter Delete
3. Follow the on screen instructions. Type in the Key ID and the Seed numbers when prompted.
4. If adding a transmitter. After programming , point a transmitter at the vehicle
and attempt to lock / unlock the vehicle. If the vehicle
does not lock / unlock, attempt to lock / unlock using
the second transmitter from the pack.
After a successful ‘Transmitter add’ operation delete the
Key ID and Seed numbers taken from the packaging
label.
The remaining Key ID and Seed numbers are for the
remaining remote transmitter. Ensure that they remain
together .
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 inte rvention 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 fa ils, 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 su ccessful 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 IPAT S LED will flash at 4Hz for 1
minute. The IPATS LED will then flash one of the following
codes:
Caution
Do not lose the transmitter packaging, with the number
label attached, before progra mming to the vehicle. The
remote transmitters can not be programmed without the Seed and Key ID numbers.
If the CEM is required to be renewed then all remote
transmitters must be renewed as well.
