Handling Electrical System And Electronics

• Explosion hazard in the vicinity of the battery during welding and grinding work. The battery must be Disconnected; See NOTES FOR DISCONNECTING AND CONNECTING THE VEHICLE BATTERY (M2 BASE, M2 COMPETITION, M2 CS) .

• Control units with visible mechanical damages and/or electrical damages caused by accidents must be replaced.
• 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 ground cable must be Disconnected; See NOTES FOR DISCONNECTING AND CONNECTING THE VEHICLE BATTERY (M2 BASE, M2 COMPETITION, M2 CS) 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 current temperature of the vehicle is ≤ 60 °C (object temperature).
• Protect control units against the influence of heat >65 °C (e.g. during welding and drying work with infrared beams or hot air blowers).

• Protect electrical wires and wiring harnesses against damage (e.g. during straightening and grinding work).
• Protect electrical wiring and wiring harnesses against the influence of heat >65 °C (e.g. during welding and drying work with infrared beams or hot air blowers).
• Do not kink electrical wiring.

• Follow instructions for handling Optical Fibers; See NOTES ON HANDLING OPTICAL FIBERS (M2 BASE, M2 COMPETITION, M2 CS) .
