The grey coloured fusebox shown in my pics is the 'Quiescent Current Control Module' (QCCM). I'm not sure why your car doesn't have this but there must be a valid reason? Perhaps someone else with the same car can confirm whether or not they have it?
Taken from JLR TOPIx....
"The QCCM is located adjacent to the BJB (Battery Junction Box) in the luggage compartment.
An addition to the Battery Monitoring System and using signals already transmitted by the BMS control module, the QCCM cuts the power supply to other non-essential control modules to avoid excessive discharge of the primary battery. The systems supplied via the QCCM are the audio/entertainment systems and the climate control systems.
Some control modules can cause unnecessary battery drain due to the module staying awake after the vehicle electrical system has been shut down. The QCCM, in conjunction with the GWM, monitor and control the systems to prevent battery drain.
The system consists of three components:
The Battery Monitoring System (BMS) control module.
The Gateway Module (GWM).
The Quiescent Current Control Module (QCCM).
The battery monitoring system checks primary battery health by analysing battery quiescent current, battery current drain or state of charge, and determines if any action is required to protect the primary battery. If action is required this is communicated to the GWM.
The GWM control logic uses this information to determine if action is required to assist primary battery protection. The QCCM receives open and close commands from the GWM and reacts accordingly.
The software that controls the QCCM is contained within the GWM.
The system will be set in transit mode on delivery. Transit mode has no QCCM operation and the relays remain closed. Therefore battery drain could occur and the system will not react to it.
A PDI (Pre-Delivery Inspection) process requires the system to be put into Normal mode which enables the quiescent current control module before handing over to the customer.
The QCCM has a routine to clean the relay contacts if required. This routine is performed using the Jaguar approved diagnostic system and, if unsuccessful, the unit will require replacement.
The module contains a number of fuses which supply and protect the audio/entertainment systems, and the climate systems."
I’ve attached a screenshot showing the Quiescent Current Control Module (item number 6).
