- Start the engine only with well tightened battery terminals.
- Do not use any quick chargers to start the engine instead of the battery.
- If the battery is rapidly charging, disconnect it from the on-board network.
- Before checking the injection device, make sure that the ignition system is working properly, i.e. that the ignition timing and spark plugs are correct.
- Pay attention to the reliability of the connector connection.
- Never disconnect the battery while the engine is running.
- At temperatures above 80°C (drying oven) remove the control unit.
- Do not disconnect or connect the control unit connector with the ignition on.
- When checking compression, turn off power to the fuel pump relay, remove the relay connector, see point 8.8.
