Inspection And Verification: Notes

WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
  • Eye protection must be worn at all times when working on or near any fuel related components. Failure to follow this instruction may result in personal injury.
  • This procedure involves fuel handling. Be prepared for fuel spillage at all times and always observe fuel handling precautions. Failure to follow this instruction may result in personal injury.
  • After carrying out repairs, the fuel system must be checked visually for leaks. This should be done after the engine has been run, but with the engine switched OFF  . Failure to follow this instruction may result in personal injury.
  • If taken internally, DO NOT  induce vomiting. Seek immediate medical attention. Failure to follow this instruction may result in personal injury.
  • If fuel contacts the eyes, flush the eyes with cold water or eyewash solution and seek medical attention. Failure to follow this instruction may result in personal injury.
  • Wash hands thoroughly after handling, as prolonged contact may cause irritation. Should irritation develop, seek medical attention. Failure to follow this instruction may result in personal injury.
CAUTION:
  • Before disconnecting any part of the system, it is imperative that all dust, dirt and debris is removed from around components to prevent ingress of foreign matter into the fuel system. Failure to follow this instruction may result in damage to the vehicle.
  • It is essential that absolute cleanliness is observed when working with these components. Always install blanking plugs to any open orifices or lines. Failure to follow this instruction may result in damage to the vehicle.
  • 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.
NOTE:
  • Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
  • When measuring fuel sender resistance values with a multimeter, it is critical to use the correct multimeter setting. The multimeter should not  be on the 'Auto' setting and must  be set to 'Manual'. This will help prevent incorrect diagnosis and unnecessary replacement of fuel senders. If the multimeter range is set at 'Auto' then, during a sweep of the sender from 50 Ohms to 998 Ohms, the multimeter has to change its measurement range. For approximately 1 second, during the range switch over point, the multimeter display indicates an open circuit. This can lead to a mis-diagnosis of a fuel sender fault.
  1. Verify the customer concern
  2. Visually inspect for obvious signs of damage and system integrity
