Land Rover Discovery: Fuel Charging and Controls
- Ingenium i4 2.0l Diesel
/ Diagnosis and Testing
PRINCIPLES OF OPERATION
For a detailed description of the Fuel Charging and Controls system, refer
to the relevant Description and Operation section in the workshop manual.
REFER to: Fuel Charging and Controls (303-04C Fuel Charging and Controls
- INGENIUM I4 2.0L Diesel, Description and Operation).
INSPECTION AND VERIFICATION
WARNINGS:
CAUTIONS:
NOTES:
- If a 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.
- When performing voltage or resistance tests, always use a digital
multimeter accurate to three decimal places, and with an up-todate
calibration certificate. When testing resistance always take the
resistance of the digital multimeter leads into account.
- Check and rectify basic faults before beginning diagnostic routines
involving pinpoint tests.
- Verify the customer concern
- Visually inspect for obvious signs of damage and system integrity
Visual Inspection
![Visual Inspection](images/books/227/index521(3).jpg)
- If an obvious cause for an observed or reported concern is found,
correct the cause (if possible) before proceeding to the next step
- 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
- 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
