Safety precautions
To prevent injuries to persons and/or damage to the injection and
ignition system, the following must be observed:
♦ Switch off ignition before connecting or disconnecting injection
and ignition system wiring as well as test instrument cables.
♦ If the engine is to be turned at starter speed without starting:
– Pull connectors off ignition coils with output stage (cylinders
1…8).
Note the following if testers and measuring instruments have to
be used during a road test:
♦ Test and measuring instruments must always be secured to
rear seat and operated by a second person from this location.
If test and measuring instruments are operated from front pas‐
senger 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.
