Battery Interrupt Igniter

Battery Interrupt Igniter

• Vehicles with batteries in the luggage compartment possess a battery cut-out to improve crash safety. In case of an accident, an explosion occurs in the airbag control module which causes the input wire to separate from the starter. The battery cut-out occurs pyrotechnically, using a very small explosion charge. When working on the battery or the battery cut-out, do not inadvertently remove the ignition. Always remove the negative terminal first.

• Observe the safety precautions for working on the battery cut-out,

• Observe the information for disposal of the battery cut-out unit,
