Ignition System: Service Precautions

Safety Precautions

To prevent injuries to persons and/or damage to the fuel injection and ignition system, note the following:
- Do not touch or disconnect ignition wiring when the engine is running or being turned at starter speed.
- Switch the ignition off before connecting or disconnecting injection or ignition system wiring or tester cables.







- If the engine requires cranking without starting, e.g. when checking compression, disconnect the 5-pin harness connector from the ignition coil (arrow).

WARNING!
- Due to weight, size and need for manual operation of test instruments while vehicle is driven on public roads, instrument must be used only with a Driver operating the vehicle and an Instrument Operator operating the test equipment
- Do not use instrument with Driver only. Always use two persons to conduct testing.
- Do not place instrument on lap of Driver or front seat passenger because emergency stop may dislodge instrument and cause airbag deployment with risk of injury to Instrument Operator.
