Ignition/Glow Plug System

Safety Precautions

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

CAUTION!
• Test and measuring equipment must always be secured to the rear seat and be operated from there by a second person.

• If test and measuring instruments are operated from the front passenger seat and the vehicle is involved in an accident, there is a possibility that the person sitting in this seat may receive serious injuries when the airbag is triggered.

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 wires of ignition system when engine is running or turning at starting RPM.

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

• If the engine is to be cranked at starting RPM without starting (for example during compression test), disconnect electrical connectors on ignition coils and on fuel injectors. After performing work, check and erase DTC memory.

• Clean engine only with the ignition switched off.

CAUTION!
• The battery must only be disconnected and connected with the ignition is switched off, since the engine control module can otherwise be damaged.

• Observe safety precautions when disconnecting the battery.
