Central Door Locking

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

When the Radio Frequency (RF) receiver detects a signal from the smart key, it relays the information on the serial communication line to the Remote Function Actuator (RFA). The RFA checks to make sure that the signal is from a valid smart key. If the signal is valid the RFA transmits the request to the Body Control Module/Gateway Module (BCM/GWM) on the High Speed (HS) Controller Area Network (CAN) body systems bus.

If the request is to open the luggage compartment, the BCM/GWM operates the motor in the luggage compartment lid latch, to release the lid. If the vehicle alarm system was armed prior to the lid opening, it remains active while the luggage compartment is open. The intrusion and inclination sensing functions (if equipped and activated) are inhibited until the lid is closed. The perimeter sensing for the doors and the hood remains active. The vehicle alarm system re-arms to its previous state when the luggage compartment lid is fully closed.

If the request is to exterior lock/unlock the vehicle, the BCM/GWM sends a lock/unlock command to the door modules on the HS CAN body systems bus. The door modules then lock or unlock the door latches appropriately.

To confirm operation of an exterior single lock request, the BCM/GWM flashes the turn signal indicators once when it locks the vehicle.

To confirm operation of an exterior double lock request, the BCM/GWM flashes the turn signal indicators twice. There is a short flash for single lock, followed by a long flash (1 second) for double lock.

To confirm operation of an unlock request, the BCM/GWM flashes the turn signal indicators twice. There is a short flash, followed by another short flash.

If a door, the luggage compartment lid or the hood is ajar when an attempt to lock the vehicle is made, an error tone is emitted. The doors will not be locked and access to the luggage compartment will remain enabled.

If a smart key is left inside the passenger compartment or the luggage compartment and the vehicle is exterior locked via another smart key, the smart key left inside the vehicle will be disabled from passively starting the engine. Passive locking functions shall also be disabled.

If a smart key is left inside the passenger compartment or the luggage compartment and the vehicle is exterior locked via another smart key, an audible warning will sound and the luggage compartment will re-open after 3 seconds.

Depending on vehicle specification, the following functions offered by the CDL system: 

The vehicle can be centrally locked and unlocked from inside using the interior lock/unlock switches. Use of the interior lock/unlock 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 fully unlocked, the luggage compartment lid can be opened using the interior and exterior release switches. For the exterior luggage compartment lid release switch to operate, the transmission must be in PARK.
