Handling Electrical System And Electronics

1.0 Battery 

• Explosion hazard in the vicinity of the battery during welding and grinding work. The battery must be removed; refer to NOTES FOR DISCONNECTING AND CONNECTING THE VEHICLE BATTERY .

2.0 Control units 

• 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 prior to all repair work; refer to NOTES FOR DISCONNECTING AND CONNECTING THE VEHICLE BATTERY .

• 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).

3.0 Electrical wires and wiring harnesses 

• 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.

4.0 Optical fibers 

• Follow instructions for handling optical fibers; refer to NOTES ON HANDLING OPTICAL FIBERS .
