Diagnosis and Testing
Principles of Operation
For a detailed description of the engine ignition system and operation, refer to the relevant Description and Operation section
of the workshop manual. REFER to: (303-07B Engine Ignition - V8 5.0L Petrol/V8 S/C 5.0L Petrol)

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.
NOTE: 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 and electrical damage.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

DIAGNOSTICS
The ECM stores each fault as a DTC (diagnostic trouble code). The DTC and associated environmental and freeze frame data can be read using Jaguar approved diagnostic equipment, which can also read real time data from each sensor, the adaption
values currently being employed and the current fueling, ignition and idle speed settings.
ENGINE CONTROL MODULE Component Description

Removal and Installation
Removal
NOTE: Removal steps in this procedure may contain installation details.
1. WARNING: Do not work on or under a vehicle supported only by a jack.
Always support the vehicle on safety stands.
Raise and support the vehicle.
2. Refer to: Air Deflector (501-02 Front End Body Panels, Removal and Installation).
3. Refer to: Engine Oil Draining and Filling (303-01D Engine - V8 S/C 5.0L Petrol, General Procedures).
Installation
4. CAUTION: Be prepared to collect escaping fluids.
Torque: 11 Nm
1. CAUTION: A new O-ring seal is to be installed.
To install, reverse the removal procedure.
1 Securing ring 2 Shaft oil seal 3 O-ring seal 4 Pump housing 5 Ring gear 6 Crescent spacer 7 Roller bearing 8 Impeller 9 Centering pin 10 Spring washer 11 Outlet port (high pressure) 12 Inlet port (low pressure) The pump comprises a housing, a crescent spacer, an impeller and a ring gear. The housing has inlet and outlet ports to direct
flow and is located in the intermediate plate by a centering pin. The pump action is achieved by the impeller, ring gear and
crescent spacer.
The crescent spacer is fixed in its position by a pin and is located between the ring gear and the impeller. The impeller is
driven by drive from the torque converter hub which is located on a needle roller bearing in the pump housing. The impeller
teeth mesh with those of the ring gear. When the impeller is rotated, the motion is transferred to the ring gear which rotates
in the same direction.
The rotational motion of the ring gear and the impeller collects fluid from the intake port in the spaces between the teeth.
When the teeth reach the crescent spacer, the oil is trapped in the spaces between the teeth and is carried with the rotation
of the gears. The spacer tapers near the outlet port. This reduces the space between the gear teeth causing a build up of fluid
pressure as the oil reaches the outlet port. When the teeth pass the end of the spacer the pressurized fluid is released into
the outlet port.
The fluid emerging from the outlet port is passed through the fluid pressure control valve. At high operating speeds the
pressure control valve maintains the output pressure to the gearbox at a predetermined maximum level. Excess fluid is
relieved from the pressure control valve and is directed, via the main pressure valve in the valve block, back to the pump inlet
port. This provides a pressurized feed to the pump inlet which prevents cavitation and reduces pump noise.

Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol - Diagnostics
Diagnosis and Testing
Principle of Operation
For a detailed description of the automatic transmission/transaxle, refer to the relevant Description and Operation section n
the workshop manual. REFER to: (307-01B Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L
Petrol)
Transmission Description (Description and Operation), Transmission Description (Description and Operation), Transmission Description (Description and Operation).
Fluid Level and Condition Check
CAUTION: The vehicle should not be driven if the fluid level is low as internal failure can result.
NOTE: The transmission fluid temperature must not be allowed to exceed 50°C (122°F) whilst checking level. Should the
temperature rise above this figure, abort the check and allow the transmission fluid to cool to below 30°C (86°F).
This vehicle is not equipped with a fluid level indicator. An incorrect level may affect the transmission operation and could
result in transmission damage. To correctly check and add fluid to the transmission.
REFER to: Transmission Fluid Level Check (307-01B Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol, General Procedures).
High Fluid Level
A fluid level that is too high may cause the fluid to become aerated due to the churning action of the rotating internal parts.
This will cause erratic control pressure, foaming, loss of fluid from the vent tube and possible transmission damage. If an
overfill condition is identified, with the engine at idle ensure the fluid temperature is within the specified range and allow the
excess fluid to drain until a small thread of fluid runs from the filler/level plug hole.
Low Fluid Level
A low fluid level could result in poor transmission engagement, slipping, or damage. This could also indicate a leak in one of
the transmission seals or gaskets.
REFER to: Transmission Fluid Level Check (307-01B Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol, General Procedures).
Adding Fluid
CAUTION: The use of any other type of transmission fluid other than that specified can result in transmission damage.
If fluid needs to be added, add fluid in 0.50 liter increments through the fill hole Opening. Do not overfill the fluid. For fluid
type, refer to the General Specification chart in this section.
REFER to: Specifications (307-01B Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol, Specifications).
Fluid Condition Check
1. Check the fluid level.
REFER to: Transmission Fluid Level Check (307-01B Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol, General Procedures).
2. Observe the color and the odor of the fluid. The color under normal circumstances should be Honey.
3. Allow the fluid to drip onto a facial tissue and examine the stain.
4. If evidence of solid material is found, the transmission fluid pan should be removed for further inspection.
NOTE: In the event of a transmission unit replacement for internal failure, the oil cooler and pipes must also be replaced.
Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.
