2. 0 Control Units

• The following risks exist when the battery is connected:
  • Damage to control units resulting from welding work on the body or a line short circuit.
  • Accidental activation of airbags during straightening work on the body.

Because of these risks the battery negative lead must be DISCONNECTED prior to all repair work.

• Control units are designed for a temperature of 65 °C. The temperatures in a spray booth do not pose any problems. If a vehicle is in the spray booth at a displayed temperature of 80°C, the actual temperature of the vehicle is ≤ 60 °C (object temperature).
• Protect control units against effects of heat >65 °C (e.g. during welding and drying work with an infrared radiator or hot air blower).
