Safety Precautions

To reduce the risk of personal injury and/or damage to the fuel injection and ignition system, always observe the following:

WARNING: The fuel system is under pressure. Place a cloth around the connection point before opening the system. Then relieve pressure carefully loosening the connection.

- Always switch off ignition before disconnecting or connecting lines of the fuel injection and ignition system, including test leads.
- If engine is to be cranked at starting RPM without starting (e.g. for compression testing), disconnect connector from ignition coils and from fuel injectors.
- During some of the tests, a malfunction may be recognized and stored by the control module. At the end of all tests and repairs, the Diagnostic Trouble Code (DTC) memory should be checked and, if necessary, erased. After erasing the Diagnostic Trouble Code (DTC) memory the readiness code must be produced.
- Always switch ignition off before cleaning engine.

WARNING:
- Safety precautions before disconnecting battery:
- Always switch ignition off before disconnecting or connecting battery. Failure to do so may damage a control module.

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

WARNING:
- 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.
