door modules.

Locking of the vehicle is performed by pressing one of the buttons located on each exterior door handle, with the Smart Key
within a one meter range of the vehicle. When the door handle button is pressed, the keyless vehicle module transmits a
low-frequency signal via the low-frequency handle antenna to the Smart Key. The Smart Key transmits a radio frequency signal
which is verified by the keyless vehicle module and allows the doors to be locked or double locked and the alarm system to be
armed.

To double lock the vehicle, the button on the exterior door handle must be pressed twice within three seconds, with the Smart
Key within one meter range of the vehicle.

If a door, engine-compartment lid or the luggage compartment lid is ajar when an attempt to lock the vehicle is made, an error
tone is emitted and no locking action will occur.
Refer to: Anti-Theft - Active (419-01A Anti-Theft - Active, Description and Operation).


Engine Compartment Lid Latches Component Description

Two engine-compartment lid latches are located on the front crossmember. An engine-compartment lid release lever is located
below the instrument panel on the left-hand 'A' pillar and is connected with a cable to the latches. An engine-compartment lid
ajar switch is integrated in the engine-compartment lid latch.

Door Latches

The door latches are located at the rear of each door and engage with a striker on the adjacent pillar. Each door latch motor
assembly contains micro-switches for lock, unlock and door ajar. Motors provide for the central door locking and the double
locking feature. The electrical control for the door latch components is provided by the CJB and RJB via the driver's and
passenger door modules.

The interior door handles are connected by a cable to the latch release mechanisms. The interior door handles also incorporate
a locking facility to allow the doors to be locked from inside the vehicle when all the doors are closed. If a door is ajar the
locking feature is inhibited.

Luggage Compartment Lid Latch

The luggage compartment latch is attached to the bottom of the lid. The latch can be released electrically by pressing the
interior release button located on the outboard side of driver's lower knee bolster; a release button is also provided on the
Smart Key. There is also a release switch on the underside of the luggage compartment lid finisher.

On NAS vehicles an emergency release cable is attached to the latch. This allows the latch to be manually opened by pulling a
handle located in the luggage compartment lid interior trim.

Fuel Filler Door

The fuel filler door is electrically locked by a motor located on the fuel door housing. The fuel door is locked when the vehicle
is locked and alarmed. The fuel door can be opened when the vehicle is unlocked or locked:

via an interior handle,
via drive-a-way locking,
via the lock switch on the fascia,
via the external door key barrel. www.JagDocs.com

DTC Index


CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00.
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer approved diagnostic system).


When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads
into account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.
