the workshop manual. Engine Cooling, Section - 303-03

Inspection and Verification


WARNING: Moving parts can cause severe injury, keep clear of moving parts, never place your hands or any part of your
body near to moving parts


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:


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required.


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component.


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

1. Verify the customer concern

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

GENERAL System Operation

The ignition coils are supplied with electrical power from the battery via a 250 A megafuse in the BJB (battery junction box)
and the ignition relay in the EJB (engine junction box). The control signal for the ignition relay is supplied by the CJB (central
junction box).

The ECM (engine control module) sends a separate signal to each ignition coil to trigger the power stage switching. The ECM calculates the dwell time from the battery voltage and engine speed, to ensure a constant energy level is produced in the
secondary coil each time the power stage is switched. This ensures sufficient spark energy is available without excessive
primary current flow, which avoids overheating and damage to the ignition coils.
The ECM calculates the ignition timing for individual cylinders from: Engine speed
Camshaft position
Engine load
Engine temperature
The knock control function
The shift control function
The idle speed control function.



IGNITION COILS Component Description



The ignition coils are installed in the cylinder head covers, under the NVH (noise, vibration and harshness) covers. Each
ignition coil locates on a spark plug and is secured to the related cylinder head cover with a single screw. Each ignition coil
incorporates a three pin electrical connector for connection to the engine harness.

Each ignition coil contains a primary and a secondary winding. The primary winding receives electrical power from the ignition
relay in the power distribution box. A power stage in the primary winding allows the ECM to interrupt the power supply, to induce a voltage in the secondary winding and thus the spark plug. A diode in the ground side of the secondary winding
reduces any undesirable switch-on voltage, to prevent misfiring into the intake manifold. The power stage limits the maximum
voltage and current in the primary winding, to protect the power stage and limit the voltage in the secondary winding. www.JagDocs.com

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
