Safety precautions

To prevent injuries to persons and/or damage to the injection and glow plug system, note the following points:

  • ◆ The ignition must be switched off before connecting or disconnecting injection or glow plug system wiring or tester cables.
  • ◆ If the engine is to be turned at starter speed without starting, e.g. when checking compressions, pull connector off injection pump.
  • ◆ Before disconnecting battery, obtain radio code for radios fitted with anti-theft coding.
  • ◆ Disconnecting and connecting the battery must only be undertaken when the ignition switched off otherwise the Diesel direct injection system control unit may be damaged.

Observe the following precautions if test and measuring instruments are required during a test drive:

  • ◆ Test and measuring instruments must be secured to rear seat and operated by a 2nd person from this location.
  • If test and measuring instruments are operated from front passenger's seat and the vehicle is involved in an accident, there is a possibility that the person sitting in this seat may receive serious injuries when the airbag is triggered.
Warning!
Secure fault reader to rear seat and operate from this position.
