Central Door Locking (CDL)

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

When the RF receiver detects a signal from the Smart key, it relays the information on the serial communication line to the KVM, which checks to ensure the signal is valid. If the signal is valid the KVM transmits the request to the BCM/GWM on the MS CAN body systems bus.

If the request is to open the luggage compartment, the BCM/GWM operates the locking motor, in the luggage compartment lid latch, to release the lid. The active anti-theft system remains active while the luggage compartment is open, but the intrusion and inclination sensing functions are inhibited. Door and hood security remains active. The active anti-theft system re-arms to its previous state when the luggage compartment closes.

If the request is to lock or unlock the vehicle, the BCM/GWM passes the request to the door modules on the MS CAN body systems bus. The door modules then lock or unlock the door latches, as appropriate.

To confirm operation of a lock or unlock request, the BCM/GWM flashes the hazard warning lamps once when it locks the vehicle and twice when it unlocks the vehicle.

If a door, the luggage compartment or the hood is ajar when an attempt to lock the vehicle is made, an error tone is emitted and the applicable panel will not lock.

If the Smart key is inadvertently left inside the luggage compartment and the vehicle is locked, an audible warning will sound and the luggage compartment will re-open after 3 seconds.

NOTE: The Smartkey may not be detected if it is placed within a metal container or if it is shielded by a device with a back-lit LCD (Liquid Crystal Display) screen, such as a smart phone, laptop (including when inside a laptop bag), games console etc.

Depending on market specification, functions offered by the CDL system include:

Single point entry or multi point entry operating modes. To change mode, simultaneously press the lock and unlock buttons on the Smart key for 3 seconds. The hazard warning lamps will flash twice to confirm the change. The change can also be achieved using the Vehicle setup menu in the IC (Instrument Cluster).
Double locking the doors from outside the vehicle if the lock switch on the Smart key is pressed twice within 3 seconds.
Drive away locking that locks the doors and fuel flap at 5 mph (8 km/h). Can be enabled/disabled using the Vehicle setup menu in the IC.
Automatic re-locking after 40 seconds. Can be enabled/disabled using Jaguar approved diagnostic equipment.

The vehicle can be centrally locked and unlocked from inside using the CDL interior switches. Use of the CDL interior switches will override the drive away locking feature for the rest of a journey. If a door is unlocked and opened, both doors will relock when the open door is subsequently closed.

When the vehicle is unlocked, the luggage compartment can be opened using the interior and exterior release switches. For the exterior release switch to operate, the transmission must be in P (park).
