Land Rover Discovery: Electronic Engine Controls
- Ingenium i4 2.0l Diesel
/ Diagnosis and Testing
PRINCIPLES OF OPERATION
For a detailed description of the Electronic Engine Controls, refer to the
relevant Description and Operation section in the workshop manual. REFER
to: Electronic Engine Controls (303-14B Electronic Engine Controls -
INGENIUM I4 2.0L Diesel, Description and Operation).
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 tested
and/or the donor vehicle.
NOTES:
- Verify the customer concern
- Visually inspect for obvious signs of damage and system integrity
Visual Inspection
![Visual Inspection](images/books/227/index41(6).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
