Belt Tensioner Control Module with Airbag - Task - GF91.60-P-4006-02C

Model 163 as of 1.12.99

Under normal service conditions the restraint systems control module (N2/7) performs the following tasks:

Self-test with terminal 15R "ON" and constant system monitoring during vehicle operation
Updates fault memory
Activates airbag indicator and warning lamp (A1e15) in the instrument cluster when an error is detected
Activates Airbag OFF malfunction indicator lamp (A1e56) upon detection of a child seat
Activates time function element (5 s. ) for the seat belt warning light (A1e9) in the instrument cluster (A1) at circuit 15 "ON"
Prevention of false deployments in normal vehicle operation through additional safety sensor
Measurement of current vehicle acceleration in the longitudinal and transverse directions
Maintains energy reserves for ignition of 5 initiators where the supply voltage breakdown over a period of 150 ms

The restraint systems control module (N2/7) in the event of a crash assumes the following tasks:

Recognition and evaluation of the collision according to type, severity and direction.
Compiles up to three event data records
Switching off engine using the respective engine control unit and initiation of emergency opening through the All-activity module (AAM) (N10) by means of a separate (analog) crash line
Recognition of switching states of following belt buckles: Left front seat belt buckle/belt lock switch (S68/7), right front seat belt buckle/belt lock switch (S68/8), left rear seat belt buckle/belt lock switch (S68/11) and right rear seat belt buckle/belt lock switch (S68/12)

Triggering of driver ETR initiator (R12/1) and the front passenger ETR initiator (R12/2)
Triggering of left rear ETR initiator (R12/6) and the right rear ETR initiator (R12/7)
up to 31.08.00: triggering of driver airbag initiator (R12/3) and the front passenger airbag 1 initiator (R12/4)
as of 1.09.00: triggering of driver airbag 1 initiator (R12/13) , the driver airbag 2 initiator (R12/14) , the front passenger airbag 1 initiator (R12/4) and the front passenger airbag 2 initiator (R12/5)
Triggering of left side airbag initiator (R12/9) and the right side airbag initiator (R12/10)
Triggering of left rear side airbag initiator (R12/11) and the right rear side airbag initiator (R12/12) (for code 293 left and right rear side airbag)

as of 1.09.01:

Triggering of left rear window airbag initiator (R12/22) and right rear window airbag initiator (R12/23)
