Inspection And Verification

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: DO NOT  remove the coolant expansion tank cap when the engine is hot. Failure to follow this instruction may result in personal injury.
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.
NOTE:
  • 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-to-date 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.
