OVERVIEW

Single Battery Vehicles Published: 18-Jun-2014

Mounted on the battery negative terminal is a BMS (battery monitoring system) module. The BMS module is integral with the
battery negative cable and is controlled by the ECM (engine control module).

CAUTION: To avoid damaging the battery monitoring system module, always use a suitable body ground point rather than
the battery negative terminal when connecting a slave power supply to the vehicle.

If a new battery is fitted to the vehicle, the BMS module will require re-calibrating using the Jaguar approved diagnostic
system.

Fitted on the battery positive terminal is a transit relay. The transit relay must be removed from the vehicle during the
Pre-Delivery Inspection (PDI). For additional information, refer to the PDI Manual.

The vehicle battery provides power to the BJB (battery junction box). The BJB contains 3 megafuses, delivering power to the RJB (rear junction box), the CJB (central junction box) and the EJB (engine junction box). In addition to containing fuses and
relays, the RJB and RJB contain software to control a number of vehicle systems. These functions are covered in the appropriate sections of this manual.
Dual Battery System Vehicles - TD42.2L Engine Variants Only

Two batteries are fitted to accommodate the dual battery system used for the Stop/Start system.

A primary battery is located in the luggage compartment floor in a plastic molded tray and secured with a metal rod. The
secondary battery is located in the DBJB (dual battery junction box).
The primary battery is a 90Ahr, 850A CCA AGM Battery.
The secondary battery is a 14Ahr, 200A CCA Absorbed Glass Mat (AGM) Battery.

A BMS (battery monitoring system) control module is mounted on the primary battery negative terminal. The BMS control
module is integral with the battery negative cable and is controlled by the GWM (gateway module).

CAUTION: To avoid damaging the BMS control module, always use the ground (negative (-)) terminal stud point on the
right side top mount. Never connect directly to the primary battery negative terminal when connecting a slave power supply to
the vehicle, the BMS control module can be damaged.

If a new primary battery is fitted to the vehicle, the BMS control module will require re-calibrating using a Jaguar approved
diagnostic system.

When the vehicle leaves the factory, a transit relay is fitted to the battery positive terminal. The transit relay is connected to
the CJB which limits the electrical functions to essential items only, to reduce loads on the primary battery. The transit relay must be removed from the vehicle during the PDI (Pre-Delivery Inspection). For additional information, refer to the PDI.

The primary battery provides power to the BJB. The BJB contains three megafuses, delivering power to the RJB, the EJB and the starter motor and generator. In addition to containing fuses and relays, the RJB and CJB contain software to control a number of vehicle systems. These functions are covered in the appropriate sections of this manual.

A jump start terminal is located adjacent to the EJB. A cover protects the terminal when not in use. If jump starting is
required, the cover must be removed and the positive (+) jump lead attached securely. The negative (-) jump lead is attached
to a stud located on the right side top mount in the engine compartment. The cover must be fitted to the positive terminal
when not in use.
Dual Battery System

The dual battery system is used on vehicles with the stop/start system. The dual battery system prevents the vehicle
electrical systems being subjected to undesirably low voltages during repeated engine restarts. If the electrical systems are
subject to low voltages the customer may notice degraded performance of components and systems and incorrect fault DTC
(diagnostic trouble code)'s may be stored.

The dual battery system isolates all electrical components and systems sensitive to low supply voltage from the primary
battery while an engine start is in progress, and supplies them from the secondary battery. Without the dual battery system,
the electrical power required by the TSS (Tandem Solenoid Starter) motor to crank the engine for each start would cause a
voltage drop across the entire vehicle electrical network, and cause control modules to function incorrectly and in some cases
reset and/or record DTC's.

If the dual battery system is unable to prevent electrical supplies to the vehicle systems being subjected to low voltage levels
during engine stop/start operations, due to the condition of the primary and/or secondary batteries or a system fault, the
stop/start feature is disabled.
