- Fuel lines must not be opened when engine is running.
- The ignition must be switched off before connecting or disconnecting injection and ignition system wiring or tester cables.
- If the DTC memory was erased, a new readiness code must be generated.
- Cleaning the engine should only be performed with ignition switched off.
- The Battery must only be disconnected and connected with the ignition switched off, since the Engine Control Module can otherwise be damaged.
