Parking Aid System On-Board Self-Test

As part of the strategy of the system if any DTCs are detected, a long high-pitched tone approx 3 seconds will sound and the
parking aid switch (where fitted) indicator LED will flash 6 times at ignition on

If a fault is present when the parking aid system is activated then the parking aid switch (where fitted) status LED will
flash 6 times indicating an issue with front or rear parking aid sensors, wiring switch, parking aid control module or hard
wired sounders
The rear parking aid sounder/rear audio system will emit an error tone for approx 3 seconds at ignition on if a fault is
detected with the front or rear sensors, the switch, or if there is a controller area network (CAN) bus error
(Only applicable to vehicles fitted with front parking aid and a hard wired rear parking aid sounder). If there is a fault
with the rear parking aid sounder the error tone will come from the front parking aid sounder unit (integral with the
instrument cluster)

Battery and Charging System - General Information - Battery Care
Requirements
Description and Operation
1. INTRODUCTION

This document defines the requirements for care and maintenance of batteries, and the standard of battery care at dealers and
retailers for new vehicles.

This applies to all types of 12 Volt Lead Acid Batteries used in Jaguar and Land Rover vehicles whether they are conventional
flooded technology or Absorbed Glass Mat (AGM – also known as Valve Regulated Lead Acid (VRLA)) technology and also
applies to both Primary, Secondary and Auxiliary Batteries. AGM batteries offer improved resistance to cycling as seen in stop
start applications.

In order to prevent damage to the battery and ensure a satisfactory service life, all processes detailed within this document
must be rigorously adhered to.
It is equally important therefore to note the following key points:

All new vehicles leave the factory with either a transit relay installed and/or have a transit mode programmed into the
vehicle control modules. The transit relay must be removed and the transit mode disabled (where applicable) using an
approved diagnostic system, NOT MORE THAN 72 HOURS before the customer takes delivery.
The battery can be discharged by the following mechanisms:
- Self Discharge: - A lead acid battery will very slowly discharge itself due to its own internal chemical processes
whether it is connected to a vehicle or not.
- Quiescent Discharge: - The vehicle electrical systems when connected to the battery will draw charge from the
battery.

12 Volt Lead Acid Batteries rely on internal chemical processes to create a voltage and deliver current. These processes and
the internal chemical structure of the battery can be damaged if the battery is allowed to discharge over a number of weeks /
months, or is left in a discharged state for a lengthy time period.

On vehicles with conventional ignition keys, these must not be left in the ignition lock barrel when the transit relay
has been removed, otherwise quiescent current will increase and the battery will discharge more rapidly.
For keyless vehicles, the Smart Key must be stored at least 5m (16 ft) away from the vehicle when the vehicle is
parked or stored.
AGM Batteries are fully sealed and cannot have the electrolyte level topped up.


NOTE: Dealers and retailers involved in the storage / handling of vehicles and replacement batteries have a responsibility
to ensure that only a fully charged battery may be processed through the distribution selling chain.
2. GENERAL RULES FOR BATTERY CARE
2.1 Dealer Demonstration Vehicles

Vehicles used as dealer demonstrator(s), in a showroom, must be connected to a JLR approved showroom conditioner capable
of delivering 50 Amps. This will prevent the battery from being damaged.
2.2 Software Reflash, SDD work or Ignition On related workshop activities

Due to the high electrical current demand and high depth of discharge that can occur during vehicle software re-flash activities,
SDD work or ignition on (power mode 6) related work in the workshop, vehicles that are undergoing such activities MUST have a
JLR approved power supply capable of delivering 50 Amps or more.
2.3 Extended Vehicle Rework

For any extended vehicle rework that results in consuming vehicle power, either the battery should be disconnected or a JLR
approved power supply connected.
2.4 Jump Starting New vehicles before they have been delivered to the customer

It is the dealer / retailers responsibility to make sure the battery is not allowed to discharge by following the
instructions and processes defined in this manual.
However, if circumstances dictate that a new vehicle must be jump started due to a discharged battery whilst the
vehicle is in the dealer / retailers care, the battery on this vehicle must be replaced with a new one prior to delivery
to the customer at the dealer / retailers liability.
The vehicle should also undergo investigation as to why the battery became discharged.
Do not connect the jump starting cable to the negative (-) terminal of the battery. Always connect to the recommended
earth point. As defined in the owners handbook or service documentation for that vehicle. 2.5 AGM Batteries

AGM batteries must not be charged above 14.8 Volts. Doing so will damage them.
AGM Batteries must be tested with a capable battery tester as detailed in the Equipment section (Section 5) of this

5. EQUIPMENT

All equipment used must be functionally capable of meeting the compliance requirements. Please refer to the approved
equipment document (JLR 000015).

In the case of batteries fitted to a new vehicle at the dealership, battery condition should be measured using the appropriate
hand-held Midtronics tester as follows:

Battery Type Battery Tester Battery Tester Jaguar Land Rover AGM & Flooded Midtronics EXP1080, GRX 3080 Midtronics EXP1080, GRX 3080 The test results must be recorded on the New Vehicle Storage Form which is part of the new vehicle storage document.
For additional information, refer to: New Vehicle Storage Form (100-11 Vehicle Transportation Aids and Vehicle Storage, Description and Operation).


NOTE: All equipment must be calibrated
6 DETERMINING BATTERY CONDITION

TESTER RESULTS ACTION GOOD BATTERY Return to service. GOOD RE-CHARGE Fully charge battery and return to service. CHARGE AND RE-TEST Fully charge battery. Remove surface charge. Re-test battery. If same result replace battery. REPLACE BATTERY OR BAD
CELL BATTERY Verify surface charge removed. Disconnect battery from vehicle and re-test. If result repeats after
surface charge removal, replace battery. DO NOT RECHARGE. UNABLE TO DO TEST Disconnect battery from vehicle and re-test. 7 BATTERY CHARGING

It is essential that a suitably ventilated defined area exists in each dealership / retailer for battery charging.


CAUTION: It is very important that when charging batteries using the traction charger or other stand-alone chargers that
the charger is set for the correct type of battery before charging commences. If the wrong switch is selected the result would
be a battery that is not charged fully and / or overheating can occur. Follow the manufacturers operating instructions.

Batteries MUST BE tested and if necessary charged every 30 days and charged after 90 days irrespective of any test. It is
recommended that dealers / retailers always have fully charged batteries ready for use.


CAUTION: Do not charge AGM batteries with voltages over 14.8 Volts as this will damage the battery.

A designated controlled area must be allocated for scrap batteries and clearly controlled as such.
To bring a discharged but serviceable battery back to a fully charged condition proceed as follows:
Check and if necessary top-up the battery electrolyte level. (Flooded maintainable batteries only)
Charge the battery using a JLR approved charger as detailed in the approved equipment document following the
manufacturers operating instructions.


NOTE: When using the Midtronics Diagnostic Charger, automatic mode must always be used. After charging and analysis,
the charger may display ‘Top-Off Charging’, Hit STOP To End. Do not stop charging until the current falls to 5A or less,
otherwise the battery will not be fully charged.
Following charging, a post charge battery condition test must be carried out in accordance with the table shown in the
Determining Battery Condition section (Section 6) of this procedure.


NOTE: The Midtronics code from the tester must be recorded on the form.

Any actions must be carried out in accordance with the table shown in the Determining Battery Condition section (Section 6)
of this procedure. The details must be recorded on the New Vehicle Storage Form which is part of the new vehicle storage
document.
For additional information, refer to: New Vehicle Storage Form (100-11 Vehicle Transportation Aids and Vehicle Storage, Description and Operation).
8 BATTERY REPLACEMENT

If it is determined that a battery requires replacement, always refer to the appropriate section of the workshop manual for
instructions on removing and installing the battery from the vehicle.

On in service vehicles fitted with a Battery Monitoring System (BMS), the BMS control module must be reset following the
installation of a new battery. The BMS control module reset procedure must be performed using an approved diagnostic

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.
