Ignition System Safety Precautions

CAUTION:

To Reduce the Risk of Personal Injury and/or Damage to the Fuel Injection and Ignition System, Observe the Following:

Individuals with a pacemaker must not stay in the danger area of high voltage systems, for example ignition systems, xenon light.
Fuel lines must not be opened when the engine is running.
The ignition must be switched off before connecting or disconnecting fuel injection and ignition system wiring or tester cables.
If the DTC memory was erased, a new readiness code must be generated.
Cleaning the engine is only performed with the ignition switched off.
The battery may only be disconnected and connected when the ignition is switched off, otherwise it could damage the engine control module.
Remove the four connectors from the ignition coils if the engine is supposed to be driven by the cranking speed so that the engine cannot start (for example, when performing a compression test). Use the :T40039 to remove the connectors. Also remove the fuse from the Fuel Pump Control Module -J538-.
