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 with power output stages when the engine is running or turning at starting speed.
• The ignition must be turned off before connecting or disconnecting injection and ignition system wiring or tester cables.
• If engine is to be cranked at starting speed without starting:

-- Using the assembly tool -T10118-, disconnect the connectors from the ignition coils 1 through 6.

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.
