Fuel Charging and Controls - VIN Range: G00442->G45703

Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.

Visual Inspection Chart

Mechanical Electrical
Engine oil level Fuses
Cooling system coolant level Wiring harness
Fuel level Electrical connector(s)
Fuel contamination/grade/quality Sensor(s)
Throttle body Engine control module (ECM)
Poly-vee belt Transmission control module (TCM)

1. Verify the following systems are working correctly:
- Air intake system
- Cooling system
- Charging system
- Ignition system

2. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
3. If the cause is not visually evident and the Jaguar approved diagnostic system is not available, use a fault code reader to retrieve the fault codes before proceeding to the diagnostic trouble code (DTC) index chart, or the symptom chart if no DTCs are set.

CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number 3548-1358-00.

NOTE:
- When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to 3 decimal places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.
- Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
