Technical Description
Gears are shifted and selected via a
central shift rod without any losses due
to redirecting motion
Comfort element directly below the
shift lever handle to facilitate
harmonious shifting, at the same
time neutralizing engine and
transmission excitations
Decoupling to the chassis by a
large-displacement elastomer
element integrated in the casing

Supplemental Restraint System
(SRS)
39
Supplemental Restraint System
(SRS)
• SRS system with maximum of 14 ignition squibs
• New features
– Upfront sensors (B48/1 & B48/2)
à USA only
– Passenger Airbag with dual inflation system
– Occupant classification system
– Deletion of passenger seat occupancy mat (B48)
40
Occupant Classification System
• FMVSS 208 requires the progressive implementation of
advanced airbags on all production vehicles by MY 2007
• Advanced air bags systems determine the proper airbag
deployment and power levels based on any of the following:
– Occupant size / weight
– Seat belt use
– Crash Severity
• To fulfill this requirement a new occupant classification system
was developed
– Passive-Occupant-Detection-System-B (B48/5)
– SRS system adaptation (AB)
41
Occupant Classification System
• Implementation schedule
– CL 203 à Start of production (04/04)
– W/S203 à Delayed introduction approx. 07/04, but C55 AMG
will never get this system
• System design
– A silicone oil filled mat placed underneath the foam cushion
measures pressure (weight) put on the seat
– System activates to determine whether to deploy airbag and
tailors the inflation of the front passenger’s front air bag to the
occupant classification of the seated occupant
• System components (on top of SRS module)
– Bladder mat & Pressure sensor
– Belt tension sensor
– OCS control module
42
OCS Vehicle Identification
• Vehicles equipped with Advanced Air Bags need to display this
accordingly
Labels affixed to back
of sun visors
Additional label affixed to ash tray cover
(Temporary label, removed after delivery)
43
OCS – Customer Indication
• Primary Airbag state indicator is Passenger Airbag Off light
(new icon for all OCS systems as of MY05)
Location: Upper control panel (center console)
– Lit upon Ignition On (6 seconds)
– Lit until system recognizes
an occupant needing Airbag enabled
– Not lit if adult person recognized
à Airbag may still not deploy in an accident if not required
• Proper seating position (backrest) is critical for proper classification
• Passenger Airbag Off light indicates all deactivated conditions, not just
BabySmart child seats
à Light is always illuminated if no passenger seated
44
OCS – Customer Indication
• Additional reference messages displayed in instrument cluster
– Displayed only if implausible weight class change occurred that
results in an Airbag state change
• Passenger door not open
• Weight classification change without running
through class 0
– Not all Airbag state changes will trigger an instrument cluster
display message
Airbag On à Off
Airbag Off à On
45
Malfunction Indication
Note: Not a W203 C-Class instrument cluster (picture representative)
No specific message related to OCS, only SRS malfunction
Indicator for a OCS problem is additional Airbag Off light ON
despite an adult sitting in the passenger seat
46
OCS – Control Module (N2/13)
• Tasks
– Supply power (5V) to belt tension sensor (B48/3) and pressure
sensor (B48/4)
– Interpret data from pressure sensor (B48/4) attached to silicon
bladder and belt tension sensor (B48/3) attached to end of seat
belt
– Calculate weight classification of occupant on seat
– Provide weight classification and seat occupancy data on CAN B
– Self-test of ECU and sensors (upon power up) and log fault
codes
Location:
Under passenger
seat
(attached to frame)
47
OCS – Pressure Sensors (B48/4)
• Pressure sensor (B48/4)
– Measures pressure inside silicon filled bladder mat
à permanently attached to bladder mat
– Bladder mat geometry is adapted to each seat / vehicle à same
pressure measurement independent of the
pressure point area
– Permanently assigned to OCS controller due to adaptation
process at manufacturer
à tamper indicator connector
(seal discolors from pink
to purple if unplugged)
48
OCS – Belt Tension Sensor (B48/3)
• Belt tension sensor (B48/3)
– Measures tension (pull) on the seat belt at the anchor point
à permanently attached to seat belt
– Value used to determine correction factor of bladder pressure
sensor
à Seat belt anchor point is below weight measuring area
and can therefore influence reading
Location (CL shown):
W/S203 Belt anchor point at seat frame
CL203 Belt anchor point at B-pillar
49
OCS – Weight Classification
• OCS Process
– Ignition 15R initiates self-test
– Pressure present in bladder mat is measured
– Weight adjustment factor is calculated from seat belt
tension
– Weight classification is determined
– OCS sends CAN B messages
• Passenger seat occupancy state
• Passenger weight classification (0-4)
– AB sets airbag deployment state
• Enabled / Not enabled
• Deployment level (1st/ 2ndstage) based on weight class
and accident severity
– AB sends CAN message to Upper Control Panel to activate
/ deactivate Airbag Off light
50
OCS - Diagnosis and Repair
• All diagnostic procedures are in SDS/DAS 04/04
• Proper seat backrest position is vital for accurate classification
• Special Tool required for calibrating system
– Set of weights to verify accurate weight classification
• System requires calibration after OCS component replacement
51
OCS - Diagnosis and Repair
• Belt tension sensor replaced together with seat belt
à “Zero” sensor in OCS controller after installation
• Bladder mat and OCS controller only replaceable as a unit togeth er
with:
– Cushion frame
– Cushion
– Cushion cover
• Service Kit contains all of the above
• Pressure sensor should never be unplugged from control unit
à swapping for test purposes has no use since bladder
and controller are matched for tolerances
à discolored connector seal indicates tampering
