Inspection and Verification

Anti-theft - Passive

The best method to confirm the correct operation of the Passive Anti-Theft System (PATS) is to check the LED (located in the
center of the instrument panel). The LED should illuminate solid for 3 seconds, when the ignition status is set to ON, and then
extinguish. This validates all PATS functions (i.e. the key transponder matches a stored key code, the challenge/response
sequence between the respective modules was successful resulting in the EMS being enabled).
Ignition fails to operate

Check that the smart key is located within the vehicle interior, and that it is the correct one for the vehicle.

Insert the smart key into the start control unit (located at out board side of driver instrument panel lower panel), this is an
alternative method to allow Ignition On/Engine Start.



Check that the start button circuit to the CJB is not open circuit or short circuit to power.

Check that the Low Speed CAN network is not malfunctioning, i.e. open circuit or short circuit. This would mean that the
remote keyless entry module, Central Junction Box (CJB) and instrument cluster would be unable to communicate.
Engine fails to crank

If a PATS fault is detected, the LED will flash for 60 seconds at 4Hz with a 50% duty cycle. At the end of this period, the LED
will flash a 2 digit code; this code is repeated 10 times. The meaning of these fault codes along with the frequency of flashing
is given in the accompanying table. As a general rule a fault code of 16 or less will cause the vehicle not to crank. Additionally,
the manufacturer approved diagnostic system should be used to check the instrument cluster, CJB & ECM for Diagnostic Trouble
Codes (DTCs).
One potential occurrence for failing to crank could be due to the P & N start switch (input to the ECM).
Check the Crank Request output from the CJB to ECM is not short circuit to ground or open circuit. www.JagDocs.com

System Operation

The hinged panels are secured with latches and strikers. A remotely operated central locking system controls the locking and
unlocking of the door and luggage compartment latches. A radio frequency Smart Key allows the vehicle to be locked and
unlocked by pressing the appropriate handset buttons. Two levels of central locking system are available: remote central
locking and an optional passive entry system.

The passive entry and associated passive start system allows the driver to unlock and start the vehicle without using a vehicle
key in a door-lock or ignition switch. The passive entry system is an optional fitment while the passive start system is a
standard fitment on all vehicles. The passive start system is combined with the passive anti-theft immobilization system.
Refer to: Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).
Emergency access to the vehicle is provided by two concealed key barrels: one located in the front left-hand door handle and
one located on the underside of the luggage compartment lid finisher. An emergency, removable key blade is fitted into the
Smart Key.

Operation of either key barrel unlocks the vehicle but does not disarm the alarm system. The key barrels in the door and
luggage compartment lid are concealed by a plastic cover which can be removed by inserting the blade of the emergency key
into a slot in the cover.
Locking and unlocking conditions using the emergency key in the door key barrel:
If the alarm is not armed the vehicle can be centrally unlocked.
If the alarm is armed the door only can be opened and the alarm will be triggered.
The vehicle cannot be double locked or the alarm system armed using the emergency key.

The vehicle can be centrally locked and unlocked from inside using the interior handle release levers on the front doors only.
Central locking and unlocking can also be performed using lock and unlock buttons on the vehicle's fascia. The driver can select
locking options, single point entry or drive away locking for example, from a menu available on the touch screen.

Central Locking – Radio Frequency Remote System

The radio frequency central locking system, provides locking and unlocking of the vehicle from inside and outside of the
vehicle. The system is operated using buttons on the Smart Key, which transmits radio frequency signals to the central locking
radio frequency receiver.

The system provides additional security by double-locking the doors from outside the vehicle if the lock button, on the Smart
Key, is pressed twice within 3 seconds; this function is not applicable in North American Specification (NAS) and Japanese
markets.

Additional buttons on the Smart Key provide for the convenience operation of the luggage compartment lid release, headlamp
delay and panic alarm functions. A global open or close feature is also available in certain markets using the lock/unlock
buttons.

Passive Entry

On vehicles fitted with the optional passive entry system, the vehicle can be unlocked without the use of a key blade or
pressing buttons on the Smart Key. The Smart Key operates the passive entry system in addition to the passive start system.
Refer to: Anti-Theft - Passive (419-01B Anti-Theft - Passive, Description and Operation).
The passive entry system is controlled by the keyless vehicle module and five low frequency antennas. One antenna located in
each door handle and one antenna located behind the rear bumper cover.

When a vehicle door handle is pulled to the first five-percent of its travel and the Smart Key is within one meter of the handle;
the Smart Key receives the low-frequency signal transmitted from the keyless vehicle module. The Smart Key responds with a
radio frequency transmission of its authorization code. The radio frequency signal is received by the central locking radio-
frequency receiver and passed to the keyless vehicle module which checks and approves the code as valid. Once the handle is
