WARNING:
  • Wait at least 30 seconds after stopping the engine before commencing any repair to the high pressure fuel system. Failure to follow this instruction may result in personal injury.
  • Place the vehicle in a well ventilated, quarantined area and arrange 'No Smoking'/'Fuel Fumes' signs around the vehicle. Failure to follow this instruction may result in personal injury.
  • Before working on the fuel system, ground the vehicle to earth and maintain the ground connection until the work is complete. Failure to follow this instruction may result in personal injury.
  • Do not perform any repairs to the high pressure fuel system whilst the engine is running. The fuel pressure can be extremely high. Failure to follow this instruction may result in personal injury.
  • Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components. Highly flammable vapours are always present and may ignite. Failure to follow this instruction may result in personal injury.
  • After making repairs, the fuel system must be checked visually for leaks. Failure to follow this instruction may result in personal injury.

CAUTION:
  • Before disconnecting any part of the fuel system, it is imperative that all dust, dirt and debris is removed from around components to prevent ingress of foreign matter. Failure to follow this instruction may result in damage to the vehicle.
  • It is essential that absolute cleanliness is observed when working with fuel system 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:
  • 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.
