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.

Caution
Do not lose the transmitter packaging, with the number label attached, before programming to the vehicle. The remote transmitters can not be programmed without the Seed and Key ID numbers.

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.

If the CEM is required to be renewed then all remote transmitter must be renewed as well.

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:

DTC Flash Code Description
B1681 11 Transceiver not connected
B2103 12 Transceiver antenna coil malfunction
B1600 13 No key-code from the key
B1602 14 Invalid/Partial key code from transceiver
B1601 15 Keycode not recognised (but correct format)
B1213 21 Less than two keys stored
B1342 EEPROM fault (failed store operation)
B2431 Key would not store, (key fault)
