Ignition System: Service Precautions

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 ignition coils when engine is running or turning at starting RPM.
- Only disconnect and reconnect wires for injection and ignition system, including test leads, when ignition is turned off.
- If engine is to be cranked at starting RPM without starting:







- Disconnect all 4-pin connectors (arrows) from the ignition coils.







- Remove fuse 18 from fuse holder.


NOTE: By removing fuse 18, voltage supply to the fuel injectors is interrupted.


If special testing equipment is required during road test, note the following:
- Test equipment must always be secured to the rear seat and operated from there by a second person.

If test and measuring equipment is operated from the passenger seat, the person seated there could be injured in the event of an accident involving deployment of the passenger-side airbag.
