•Disconnect the ground cable from the battery’s negative terminal before removing electronic components.
• Always use adequate measuring equipment to carry out electrical measurements on electronic components.
• Make sure that electronic device cables (length, type of conductor, positioning, clamping, shielding continuity
where required, grounding, etc.) are correct for the system and carefully restored to the original condition after service.
• Never insert or remove the connector from the electronic control units while powered.
• In case of temperatures over 80°C (drying ovens) remove the electronic control units.
• When making connections, tighten the connector nuts (temperature, pressure sensors, etc.) to the prescribed
torque ( 000800).
• Electronic control unit measuring at plugs, plug connections and electrical connections of components is to be
carried out only using the appropriate equipment. Never use improper tools such as metal wires, screwdrivers,
clips or suchlike. Besides the danger of short circuits, these methods could damage the plug connections and subsequently cause contact problems.
