SAFETY PRECAUTIONS

If testing equipment must be used during a road test, observe the following

WARNING

Improperly secured testing and measuring equipment and distraction during a road test increase the risk of an accident. The passenger airbag could pose a risk if it deploys in a collision. Operating testing equipment while driving causes it to shift position. There is an increased risk of injury due to unsecured testing equipment. Always secure testers on the rear seat with a strap and have a second person on the rear seat to operate them.

To prevent personal injury and damage to the injection and ignition system, observe the following

Individuals with a pacemaker must not stay in the danger area of the high voltage systems, for example ignition systems, xenon light.
Turn off the ignition before disconnecting and connecting the wiring for the injection and ignition system. This includes tester cables as well.
Do not touch or remove ignition wires when engine is running or turning at starter speed.
Only clean engine with ignition switched off.
If the engine is to be cranked at starting RPM without starting, disconnect the connectors from the ignition coils and fuel injectors.
While testing it is possible that there may be some faults stored in the Engine Control Module (ECM). After completing all testing and repairs, check the Diagnostic Trouble Code (DTC) memory. If a fault has been stored

CAUTION

Risk of destroying electronic components when disconnecting the battery. Observe measures for disconnecting the battery.

Disconnect the battery. Refer to Removal and Installation .

IGNITION SYSTEM

The Engine Control Module (ECM) is equipped with On Board Diagnostics (OBD).
For the electric components to work properly, a voltage of at least 11.5 Volts is required.
While testing it is possible that there may be some faults stored in the ECM. After completing all testing and repairs, check the Diagnostic Trouble Code (DTC) memory. If a fault has been stored

If the engine only starts briefly and then turns off again after troubleshooting, repair or checking of the components, it may be that the immobilizer is blocking the ECM. DTC memory must then be checked and if necessary, the control module must be adapted.
