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:

• The ignition must be turned off before connecting or disconnecting injection and ignition system wiring or tester cables.

• Do not touch or remove ignition wires when the engine is running or turning at starter speed.

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

• Test and measuring instruments must be secured to the rear seat and operated by a second person from this location.

If the vehicle is involved in a collision while testing and measuring equipment is operated from the front passenger seat, the person sitting in that seat could be seriously injured when the airbag deploys.

• If the engine is to be cranked at starter speed without starting:

- Remove the ignition coil wiring harness cover strip.






- Disconnect the connectors from ignition coils 1 through 6 using the assembly tool (T10118).

- For this purpose, install the assembly tool (T10118) to the release button - arrow - and carefully pull the connector up.






- Pull the fuse for the fuel pump out of the fuse holder.
