Lincoln Corsair: Supplemental Restraint System / Removal and Installation - Occupant Classification System (OCS) Sensor
Special Tool(s) /
General Equipment
Removal
WARNING:
The following procedure prescribes critical repair steps
required for correct restraint system operation during a crash. Follow
all notes and steps carefully. Failure to follow step instructions may
result in incorrect operation of the restraint system and increases the
risk of serious personal injury or death in a crash.
NOTICE:
To prevent system failure, carry out the OCS (occupant
classification system) reset when a front passenger seat cushion is
disassembled, a new trim cover or heater mat is installed or an OCS
(occupant classification system) service kit is installed. Use a
diagnostic scan tool to carry out the OCS (occupant classification
system) reset command.
NOTE:
OCS (occupant classification system) components (seat
cushion foam, bladder with OCSM (occupant classification system module))
are calibrated to each other and are serviced as an assembly with an
OCS (occupant classification system) service kit. If a new OCS (occupant
classification system) or seat cushion foam are needed, a new OCS
(occupant classification system) service kit must be installed. The
heater mat can be serviced separately.
NOTE:
Removal steps in this procedure may contain installation details.
-
WARNING:
Before beginning any service procedure in this
manual, refer to health and safety warnings in section 100-00 General
Information. Failure to follow this instruction may result in serious
personal injury.

-
-
Detach the front seat cushion cover J-clip.
-
On both sides.
Detach the front seat cushion cover J-clips.
-
Lift the front seat cushion foam. If the cushion foam and the OCS are
adhered together, then the OCS is a service kit. If nothing is adhered
together, then the OCS is OE (original equipment).
-
If equipped with OE (original equipment) OCS , remove the front seat cushion foam pad and cover.
-
NOTE:

from the hook-and-loop strips or the hook-and-loop strips may be torn
from the seat cushion foam pad.
NOTICE:
Use care when separating the seat cushion trim cover
from the hook-and-arrow or the hook may be torn from the seat cushion
foam pad.
NOTE:

Installation
-
NOTICE:
Inspect the OCS (occupant classification system)
bladder, seat cushion pan and support assembly for any foreign objects
before installing the OCS (occupant classification system) to the seat
cushion pan. Remove any foreign objects. Failure to follow these
instructions may result in incorrect operation of the OCS (occupant
classification system) and may cause system failure.
NOTICE:
Do not trap the pressure sensor hose incorrectly
over the seat's suspension or spring. Route the hose so that it lays in a
natural bend, and is not twisted due to being forced into an unnatural
position. Failure to follow these instructions may result in component
damage and/or system failure.
To install, reverse the removal procedure.
-
If required.
Install a new cushion heater mat.
Refer to: Seat Heater Mat Installation (501-10A Front Seats, General Procedures).
-
Bend the OCS sensor bracket tab back.
-
Install the front passenger seat. Do not prove out the SRS at this time.
Refer to: Front Seat (501-10A Front Seats, Removal and Installation).
-
WARNING:
Occupant Classification System (OCS) parts are
calibrated as an assembly and must only be replaced in the configuration
they are sold. Never separate parts of an assembly. Failure to follow
this instruction may result in incorrect operation of the OCS and
increases the risk of serious personal injury or death in a crash.
WARNING:
Make sure the front passenger seat repair is
complete, the seat and all attached components (head restraint, seat
side shield, etc.) are correctly assembled, and the seat is correctly
installed to the vehicle before using System Reset to rezero the seat
weight. Failure to follow these instructions may result in incorrect
operation of the occupant classification system (OCS) and increases the
risk of serious personal injury or death in a crash.
NOTICE:
To prevent system failure, take the following
precautions before carrying out the OCS (occupant classification system)
reset.
-
Make sure the voltage to the OCSM (occupant
classification system module) is greater than 8 volts and less than 18
volts.
-
Make sure the OCS (occupant classification
system) is not below 6º C (42.8º F) or above 36º C (96.7º F) when
initiating the OCS (occupant classification system) reset process. If
the vehicle has been exposed to extreme cold or hot temperatures, the
vehicle must be exposed and kept at a temperature between 6º C (42.8º F)
to 36º C (96.7º F) for a minimum of 30 minutes.
-
Make sure nothing is present on the
passenger seat before and during the OCS (occupant classification
system) reset process.
-
Prior to carrying out the OCS (occupant
classification system) reset, make sure a minimum of 8 seconds has
elapsed after cycling the ignition switch on.
Using a diagnostic scan tool, carry out the OCS reset. Cycle the ignition switch after the OCS reset.
-
If the first system reset attempt was successful, proceed to prove out the SRS .
-
If the first system reset attempt was not successful, carry out a thorough visual inspection of the OCS
connector and wiring for damage, pressure sensor hose for kinks and or
damage, and seat-related wiring harness and body wiring harness
terminals and connectors for damage. Repair any concerns found and
proceed to the next step.
-
Carry out a second OCS reset. Cycle the ignition switch after the OCS
reset. If the second attempt is unsuccessful, install a new OCS service
kit.
-
Prove out the SRS
. Verify all airbags are installed and connected and the ignition is
OFF. Wait 10 seconds then turn the ignition ON and monitor the airbag
warning indicator. The airbag warning indicator illuminates continuously
for approximately 6 seconds and turns off. Continue to monitor the
airbag warning indicator for approximately 30 seconds, as this is the
time required for the RCM to complete testing of the SRS .
-
If a SRS
fault is present, the airbag warning indicator either fails to light,
remains lit continuously or flashes. The flashing may not occur until
approximately 30 seconds after the ignition has been turned from OFF to
ON. If this occurs, diagnose and repair any SRS faults before proceeding with other repairs.
-
If, after the ignition has been turned on for 30
seconds, the airbag warning indicator remains unlit with no chime or SRS
message displayed in the message center, no SRS fault is present.
-
If the airbag warning indicator is inoperative and a SRS
fault exists, a chime sounds in a pattern of 5 sets of 5 beeps or a
message displays in the message center. If this occurs, diagnose and
repair the airbag warning indicator and any SRS faults before proceeding with other repairs.
-
Using a scan tool, clear all Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.

P215/65R15 95H is an example of a tire
size, load index and speed rating. The
definitions of these items are listed
below. (Note that the tire size, load index
and speed rating for your vehicle may
be different from this example.)
P: Indicates a tire, designated by the
Tire and Rim Association, that may be
used for service on cars, sport utility
vehicles, minivans and light trucks. Note:
If your tire size does not begin with a
letter this may mean it is designated by
either the European Tire and Rim
Technical Organization or the Japan Tire
Manufacturing Association.
215: Indicates the nominal width of
the tire in millimeters from sidewall edge
to sidewall edge. In general, the larger
the number, the wider the tire.
65: Indicates the aspect ratio which
gives the tire's ratio of height to width.
R: Indicates a radial type tire.
15: Indicates the wheel or rim
diameter in inches. If you change your
wheel size, you will have to purchase
new tires to match the new wheel
diameter.
95: Indicates the tire's load index. It
is an index that relates to how much
weight a tire can carry. You may find this
information in your owner’s manual. If
not, contact a local tire dealer.
