Batteries must be disconnected before structural repairs to prevent what?

Batteries must be disconnected before structural repairs to prevent what?

• A. Electrical damage or accidental airbag deployment
• B. Battery degradation during repair
• C. Increased fuel consumption
• D. Loss of tire pressure

Answer: (A)

Disconnecting the battery protects safety systems and the electrical network during repairs. The airbag system and its control module are powered by the vehicle’s battery, and working around the structure with tools, metal, or welding can create sparks or electrical noise that might trigger a deployment if power remains connected. Isolating the battery removes the energy source, reducing the risk of accidental airbag deployment and potential damage to wiring or modules from voltage surges. The other options aren’t related to the risks involved in structural repairs—battery degradation, fuel use, or tire pressure don’t come into play here.
