The odometer displays the total distance which the vehicle has traveled. This is calculated by the instrument cluster using 
wheel speed signals from the ABS module.  
The odometer can show 6 characters and distances up to 999,999 miles or kilometers. The total distance travelled is stored in a 
EEPROM (electrically erasable programmable read only memory) and the RAM (random access memory). This ensures that the 
total distance is not lost if the battery is disconnected. 
 
The odometer value is passed to other vehicle system modules on the medium speed and high speed CAN bus. This is used to record the total vehicle mileage for diagnostic purposes and when storing DTC (diagnostic trouble code)'s.

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 and Charging System - General Information - Quiescent Drain 
Description and Operation 
 
VEHICLE QUIESCENT CURRENT TESTING 
 
On vehicles fitted with a Battery Monitoring System (BMS), the diagnostic routine for quiescent drain testing in the approved 
Jaguar or Land Rover diagnostic system should be utilized. 
 
If a customer complains of a vehicle battery that discharges continuously or when left for a prolonged period of time, it is 
recommended that a quiescent drain test is performed as described below. 
 
The battery drain should be measured using the approved Jaguar or Land Rover diagnostic system or a Digital Multi-Meter 
(DVOM). A procedure for quiescent drain measurement using the diagnostic system is available in the Diagnosis and Testing 
section of the Workshop Manual. The vehicle should be in the locked/armed state (for example vehicle alarm fully armed), all 
doors, engine and luggage compartment lids are open and latched (so as to appear closed from an electrical point of view). 
The test should take place after the vehicle has entered shutdown mode. The time taken for this to occur after the ignition is 
switched off varies according to model (Refer to the Topix On line resource for details). 
 
When the vehicle is armed, the effect of the security system Light Emitting Diode (LED) flashing is to cause a pulsation in the 
measured current drain. In this case, either the average current should be taken (using a Digital Multi- Meter (DVOM) with an 
averaging system) or the current reading taken, ignoring the brief high current peaks. 
EQUIPMENT 
Approved Jaguar or Land Rover diagnostic system with current probeOR Digital Multi-Meter (DVOM) with current probe. 
 
METHOD OF MEASUREMENT 
 
Using an Approved Jaguar or Land Rover Diagnostic System. 
1. Switch off all electrical loads and ensure that the ignition is off 
2. Connect the current probe to the approved Jaguar or Land Rover diagnostic system 
3. Calibrate the probe 
4. Install a clamp around the battery lead/junction box lead 
5. Go to the Quiescent Current Testing section in this procedure 
 
Using a digital multimeter 
 
Do not use an in-line DVOM to measure the quiescent drain on vehicles fitted with an electronic throttle (for example XK 2006 
onwards). The current exceeds the maximum amount the fuse in the DVOM is capable of handling. 
1. Switch off all electrical loads and ensure that the ignition is off 
2. Connect the current probe to the digital multmeter 
3. Calibrate the probe 
4. Install a clamp around the battery lead/junction box lead 
5. Go to the Quiescent Current Testing section in this procedure 
 
QUIESCENT CURRENT TESTING 
 
1. Switch ignition to ‘on’ or select ignition mode in keyless vehicles and switch to ‘off’ (do not crank) 
2. Remove key from ignition switch (if equipped) 
3. Open and latch all doors, hood and luggage compartment lid 
4. Lock the vehicle using the remote function on the remote handset. (Single lock only to avoid volumetric alarm arming) 
5. Remove any other potential electrical drains such as accessories plugged into accessory sockets 
6. Record the amperage readings after the shutdown period referenced in the Topix on line resource for details. Note all 
cars from 10MY onwards and XK from 07MY and XF from 08MY should be less than 30mA after 30 minutes 
7. Record the final reading on the battery report form 
 
The preferred method of testing following an excessive current consumption figure is to use a current probe around individual 
junction box leads to the various suspected circuits to identify a potential cause. This is in preference to the old method of 
removing fuses for the following reasons: 
 
The drain may be caused by a module remaining active and preventing the quiescent drain from reducing to normal 
levels 
The drain may be caused by a relay winding that is activated. Pulling the fuse can allow this to ‘reset’ and the drain will 
be lost and go un-diagnosed 
 
QUIESCENT DRAIN - TYPICAL VALUES 
 
 
NOTE: The quiescent drain after the initial shutdown period should not exceed the value shown in the table.
