Primary Battery - All Vehicles

WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

The primary battery is located in a plastic tray under the luggage compartment floor in the right side of the luggage compartment, adjacent to the spare wheel. The battery is vented via a tube which is connected with a T piece to the vent from the secondary battery (if fitted) and passes through a grommet in the floorpan.

On new vehicles the primary battery positive terminal is fitted with a transit relay. The transit relay must removed using the correct process detailed in the Pre Delivery Inspection (PDI) information.

The battery negative terminal is fitted with a BMS control module. The control module is integral with the battery negative cable and communicates with the GWM via a LIN bus connection. The battery condition information is passed to the GWM which controls the generator output accordingly.

CAUTION: To avoid damage to the BMS control module, always use the body ground point in the engine compartment and not the battery negative terminal when connecting a slave power supply.

Failure to use the recommended ground point will lead to the setting of a DTC. Incorrect information of battery condition will be retained by the BMS control module due to the unmonitored current flow into the battery. The system will however, recognize and compensate for the change in battery status after a period of time.

If a new battery is fitted, the BMS control module will require recalibration using a Jaguar approved diagnostic system. Replacement of the BMS control module requires no action as the control module will re-calibrate automatically.
