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-.
