Safety Precautions

Safety Precautions

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

• If the engine is to be cranked at starting RPM without starting, for example during a compression test, disconnect the electrical connectors from the ignition coils with power output stages and the 8 pin electrical connector for the fuel injectors - 3 -.





• After performing the work, check and erase the Diagnostic Trouble Code (DTC) memory. Refer to "Guided Function".

• Do not touch or disconnect the ignition coils with power output stages when engine is running or turning at starting RPM.

• Only disconnect and reconnect the wires for injection and ignition system, including test leads, when ignition is switched off.

• The battery must only be disconnected and connected with the ignition off, otherwise the Engine Control Module (ECM) can be damaged. Obtain radio code for radios with anti theft codes before disconnecting the battery.

• Observe the required safety precautions after connecting the battery.

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

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

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.
