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) manual.

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 re-calibration using a Jaguar approved diagnostic system.
Replacement of the BMS control module requires no action as the control module will re-calibrate automatically.

SECONDARY BATTERY - DUAL BATTERY VEHICLES ONLY

The secondary battery is located in a tray on the next of the primary battery and is secured to the DBJB with a bracket. The
battery negative (-) terminal is connected via a cable to the vehicle body. The positive (+) terminal is connected by a cable to
the DBJB. The battery is vented via a tube which is connected with a T piece to the vent from the primary battery and passes
through a grommet in the floorpan.
The state of charge of the secondary battery is monitored by the Gateway Module (GWM).

BATTERY MONITORING SYSTEM (BMS)



The BMS (battery monitoring system) control module is located on the primary battery negative (-) terminal. The module is
located on the battery post and is clamped to the post with a bolt and nut.

The primary battery negative ground cable is connected to the BMS control module and is attached to a ground stud on the
vehicle body.

The BMS control module is connected into the vehicle wiring harness via a multiplug. The BMS control module receives a 12V
power supply direct from the primary battery positive terminal. A LIN (local interconnect network) bus connection provides
communication between the BMS control module and the ECM for control and monitoring of the primary battery current drain and state of charge.
The BMS control module measures battery current and voltage, which it communicates to ECM.

CAUTION: Due to the self-calibration routine, it is recommended that all power supply diagnostic testing is carried out
using the Jaguar approved diagnostic system rather than a digital multimeter.

The BMS control module is able to generate DTC (diagnostic trouble code)'s to help diagnose primary battery or generator
power supply issues. These DTC's can be read using the Jaguar approved diagnostic system. The Jaguar approved diagnostic
system can also be used to implement a primary battery and generator self test routine. For additional information, refer to
the Diagnosis and Testing section of the workshop manual.
If a fault is detected, the GWM (gateway module) will override the BMS control module.

The BMS control module DTC's can be used to help diagnose battery or generator power supply faults. The DTC's are stored in
GWM. The Jaguar approved diagnostic system has a process for an automated power supply diagnostic procedure. The
procedure provides a menu driven process to locate a fault in a logical sequence. The procedure uses the capability of the BMS
control module and generator LIN bus controlled functions to provide current flow information and will detect if the BMS control
module or generator are functioning correctly.

DUAL BATTERY MODULE (DBM)



The DBM (dual battery module) is located at the rear of the right wheel arch in the luggage compartment, adjacent to the
GWM (gateway module) and the RJB (rear junction box). The DBM is attached to a bracket, which is attached to a second
bracket secured to the vehicle body.

The DBM is connected by two hardwired connections to the DBJB (dual battery junction box). The DBM uses these two
connections to apply battery voltage to the contactor coils in the DBJB. A LIN bus connection from the GWM passes contactor operation signals to the DBM which operates the contactors as applicable.

The GWM will also instruct the DBM to apply charging to the secondary battery via a LIN bus message. The GWM instructs the
DBM of the charging current required for the secondary battery and the DBM applies the requested stabilized current to the
secondary battery via a dedicated connection direct to the secondary battery.
The DBM diagnoses the coils of the contactors and will report a fault via the LIN bus to the GWM.
The DBM receives a fused power supply from the RJB. www.JagDocs.com

Principles of Operation Published: 10-Mar-2014

For a detailed description of the battery system and operation, refer to the relevant Description and Operation section of the
workshop manual. REFER to: Battery and Cables (414-01 Battery, Mounting and Cables, Description and Operation).
Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.
NOTES:


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer-approved diagnostic system).


When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads
into account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.
1. Verify the customer concern.

2. Visually inspect for obvious signs of mechanical or electrical damage.

systems.

A typical example of information transfer is vehicle speed information from the ABS (anti-lock brake system) module used to
control the automatic volume control function. The vehicle speed information from the ABS module is sent on the high speed
CAN network and collected by the instrument panel gateway. The signal is passed to the medium speed CAN network and onto the ICM gateway. The ICM calculates the volume adjustment required. The corrected audio volume level signal is sent on the
MOST network to the IAM or Power amplifier (dependant on vehicle equipment level) for output to the speaker system.

AUDIO SYSTEM USER CONTROLS
