Battery Interrupt Igniter, Removing And Installing: Removing
- Follow all safety precautions when working with pyrotechnic components. Refer to SAFETY PRECAUTIONS .
- 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- comes on after a vehicle accident, 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 circuit electrically each time an airbag is deployed. The Battery Interrupt Igniter -N253- must always be replaced after a deployment.
The Battery Interrupt Igniter -N253- is available as a replacement part only together with Fuse Panel A -SA-.
When just replacing the Battery Interrupt Igniter -N253-, remove it from the replacement part and install it in Fuse Panel A -SA- as follows.
-- Switch the ignition on.
-- Disconnect the battery ground cable with the ignition turned on. Refer to BATTERY .
-- Remove the tool kit mount.
-- Remove the nuts -2 and 3-.
-- Unlock the spring -3-.
-- Lift the lid -2- over Fuse Panel A -SA- slightly upward -arrow- and, at the same time, remove the battery interrupt igniter.
Ignore -1-.
Before handling pyrotechnic components (for example, disconnecting the connector), the person handling it must "discharge static electricity". For example, this can be done by briefly touching the door striker.
-- Remove the battery interrupt igniter -4-.
-- To do this, release the connector lock -5- and remove the connector -1-.
