Safety Precautions
To reduce the risk of personal injury and/or damage to the fuel injection and ignition system, always observe the following:
• Do not touch or disconnect the ignition coils with power output stages when the engine is running or turning at starting RPM.
• Only disconnect and reconnect wires for the injection and ignition system, including test leads, when the ignition is switched off.
If special testing equipment is required during a road test, note the following:
• Test equipment must always be secured in the rear seat and operated from there by a second person.
If test and measuring instruments are operated from the front passenger 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.
