Symptom Possible Causes Action Parking aid sensors are being
returned with no faults found
or signs of water
ingress/corrosion Possible issue with sensor connectors
not latched correctly
When either no/intermittent operation has been
reported the following action should be taken
1. Using Datalogger, identify the position of the
suspect parking aid sensor within the bumper
2. Visually locate the position of the suspect
parking aid sensor. Inspect and provide details in
claim if the sensor has any sign of physical
damage
3. Remove the bumper. Disconnect the wiring at
the main harness connector. Inspect the main
harness connectors and terminals for signs of
damage, backed out pins, corrosion and water
ingress, or damage to the seals. Provide details in
claim if any of the above symptoms are present
4. Attempt to remove the harness connector from
the suspect parking aid sensor without using the
connector latch i.e. lightly pull back on ALL wires
together, ensuring the harness is held close to the
back of the connector, not elsewhere on the wiring
harness. DO NOT apply excessive force. If the
connector can be removed without using the latch,
provide details in claim if connector is loose. If the
connector is fully latched, disconnect it from the
sensor
5. Inspect and provide details in claim if the
suspect sensor harness connector has any sign of
water ingress/corrosion
6. Inspect and provide details in claim if the
suspect parking aid sensor harness connector
shows any sign that the terminals have backed-out
of the connector or for any damage to the terminal
seals. Replace/repair the harness as required and
proceed
7. Remove the suspect parking aid sensor from the
bumper. Inspect the parking aid sensor connector
for signs of water ingress/corrosion. Provide details
in claim if corrosion/water ingress is present
8. Exchange the suspect parking aid sensor with
another parking aid sensor within the bumper that
is performing correctly. Reconnect all sensors and
reconnect the bumper main harness connector.
Repeat step 1. Confirm if the original fault now
appears at the new position of the suspect parking
aid sensor, if so, proceed to step 10
9. If not, carry out the appropriate open circuit and
short circuit checks between the original suspect
parking aid sensor harness connector and the
parking aid control module
10. Refit the parking aid sensors to their original
position in the bumper
11. Reconnect the parking aid sensor to the
bumper harness connector. Reconnect main harness
connector and refit the bumper
12. Repeat Step 1. If fault is still present, replace
only the faulty sensor

Battery, Mounting and Cables - Battery and Cables - Overview
Description and Operation
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.

The dual battery system comprises the following components:
Dual Battery Module (DBM).
Dual Battery Junction Box (DBJB).
Gateway Module (GWM).
Primary battery.
Secondary battery.
The GWM hosts most of the software required to control the dual battery system and components. The GWM monitors the
components and can store fault related DTC's.
The GWM also controls the charging system software in conjunction with the ECM, RJB, CJB and ABS (anti-lock brake system) control module via the high speed and medium speed CAN (controller area network) bus. The GWM software will monitor the
status of the stop/start system and determine when a stop/start event can occur. It can also intervene to maintain vehicle
systems by keeping the engine running or initiating a restart due to, for example, climate control system requirements or
request for restart from the ECM. A brake pressure signal is received from the ABS control module which will indicate to the
GWM that an engine restart is required from driver operation of the foot brake.
The GWM contains the intelligent power management system and the BMS software. Monitoring of the primary battery
condition for stop/start is controlled by the GWM and the BMS control module.
