Ignition System: Service Precautions

Safety Precautions

If special testing equipment is required during road test, note the following:


Distraction and testing equipment that is not secured properly can cause accidents.

The passenger airbag could pose a risk if it deploys in a collision.

• Operating testing equipment while driving causes it to shift position.

• There is an increased risk of injury due to unsecured testing equipment.

• Always secure testing equipment on the rear seat using a strap and have a second person in the rear seat to operate it.

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 remove ignition wires when engine is running or turning at starter speed.

• Always turn ignition off before disconnecting or reconnecting wires for the ignition system, including high voltage wiring and test leads.

• If the engine is to be cranked at starting RPM without starting (for example for compression testing), disconnect connectors from ignition coils and from fuel injectors.

• Cleaning the engine should only be performed with ignition switched off.
