GF91.60-P-4080FQ Component Description For Supplemental Restraint System Control Unit
MODEL 218





N2/10 Supplemental Restraint System control unit

Location
The Supplemental Restraint System control unit is located on the center tunnel.

Task
The Supplemental Restraint System control unit has the following tasks:
^ Reading in of sensors and signals
^ Evaluation of input factors
^ Actuation of components

Reading in of sensors and signals
The input factors are read in via the following connections:
^ Direct line
^ Chassis CAN (CAN E) (with code (494) USA version)

Direct line
The signals from the following sensors are read in via a direct line:
- Left sidebag sensor (A53)
- Right sidebag sensor (A54)
- Front passenger seat occupied recognition (B41/1) (without code (U18) Automatic child seat recognition (ACSR [AKSE]) and without code (494) USA version)
- Front passenger seat occupied recognition and ACSR (B48) (with code (U18) automatic child seat recognition (ACSR))
- Left frontal acceleration sensor (B48/1)
- Right frontal acceleration sensor (B48/2)
- Left front door pressure sensor (B48/7)
- Right front door pressure sensor (B48/8)
- Left rear door pressure sensor (B48/9) (with code (293) Left and right rear sidebag)
- Right rear door pressure sensor (B48/10) (with code (293) Left and right rear sidebag)
- Driver seat belt buckle restraint system switch (S68/3)
- Front passenger seat belt buckle restraint system switch (S68/4)

Chassis CAN (with code (494) USA version )
The status of the seat occupied recognition is provided by the weight sensing system control unit (WSS) (N110) to the interior CAN (CAN B) and relayed by the front SAM control unit with fuse and relay module (N10/1) over the chassis CAN to the Supplemental Restraint System control unit.

Evaluation of input factors
The input factors that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.

Actuation of components
The actuation of the components takes place via the following connections:
^ Direct line
^ Chassis CAN

Direct line
The following components are actuated via a direct line:
- Pyrofuse 150 (F32f150) (without code (B03) ECO start/stop function)
- Pyrofuse (F63) (with code (B03) ECO start/stop function)
- Driver ETR squib (R12/1)
- Passenger ETR squib (R12/2)
- Front passenger airbag squib 1 (R12/4)
- Front passenger airbag squib 2 (R12/5)
- Left rear emergency tensioning retractor squib (R12/6)
- Right rear emergency tensioning retractor squib (R12/7)
- Driver sidebag squib (R12/9)
- Front passenger sidebag squib (R12/10)
- Left rear sidebag squib (R12/11) (with code (293) Left and right rear sidebag
- Right rear sidebag squib (R12/12) (with code (293) Left and right rear sidebag)
- Driver airbag squib 1 (R12/13)
- Driver airbag squib 2 (R12/14)
- Left windowbag squib (R12/22)
- Right windowbag squib (R12/23)
- Driver kneebag squib (R12/25) (with code (294) Kneebag)
- Driver pelvis airbag squib (R12/41) (with code (291) PELVIS AIRBAG (PELVISBAG))
- Front passenger pelvis airbag squib (R12/42) (with code (291) PELVIS AIRBAG (PELVISBAG))
- Driver seat NECK-PRO head restraint solenoid (Y24/12)
- Front passenger seat NECK-PRO head restraint solenoid (Y24/13)
- Analog crash output to the ME-SFI [ME] control unit (N3/10) (for gasoline engine) or to the CDI control unit (N3/9) (for diesel engine)

Chassis CAN
The signals are sent by the Supplemental Restraint System control unit over the chassis CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
