Battery Interrupt Igniter, Removing And Installing: Removing
- Follow all safety precautions when working on pyrotechnic components. Refer to SAFETY PRECAUTIONS WHEN WORKING WITH PYROTECHNIC COMPONENTS .
- Follow all regulations when disposing of pyrotechnic components. Refer to AIRBAG, BELT TENSIONER AND BATTERY CUT-OUT UNITS, STORING, TRANSPORTING AND DISPOSING (PYROTECHNIC COMPONENTS) .
If the Airbag Indicator Lamp -K75- turns on after a collision, check whether crash data is stored using the Vehicle Diagnostic Tester . If this is the case, check if the malfunction >>Resistance too high<< for the Battery Interrupt Igniter -N253- is stored in the DTC memory. If this is the case, the Battery Interrupt Igniter -N253- must be replaced.
The Battery Interrupt Igniter -N253- interrupts the electrical circuit each time an airbag is deployed. The Battery Interrupt Igniter -N253- must be replaced after a deployment.
