Ford Ecosport: Supplemental Restraint System / Removal and Installation - Occupant Classification System (OCS) Sensor - Vehicles With: Rear Seat Side Airbag
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 reset when a front
passenger seat cushion is disassembled, a new trim cover is installed or
an OCS service kit is installed. Use a scan tool to carry out the OCS
reset command.
NOTICE:
The cushion heater mat on a front outboard passenger seat is
not serviced separately. If a new cushion heater mat is needed on the
front passenger seat, install an OCS service kit equipped with a heater
mat. Failure to follow this instruction may result in incorrect
operation of the OCS .
NOTE:
OCS components (seat cushion foam pad, bladder with OCSM ) are
calibrated to each other and are serviced as an assembly. The OCS
components are not to be installed separately. If a new OCS , OCS
component or seat cushion foam pad are needed, a new OCS service kit
(seat cushion foam pad, bladder with OCSM ) must be installed as an
assembly.
NOTE:
Removal steps in this procedure may contain installation details.

NOTE:
When equipped with an OCS service kit, the OCS is adhered to the bottom
of the front seat cushion foam. This requires the cushion cover, foam
and OCS to be positioned aside as an assembly.
Lift the cushion foam. If the cushion foam and OCS are adhered
together, then the OCS is a service kit. If nothing is adhered together,
then the OCS is OE (original equipment).

Installation
-
NOTICE:
Inspect the OCS bladder, seat cushion pan and support assembly for any foreign objects before installing the OCS
to the seat cushion pan. Remove any foreign objects. Failure to follow
these instructions may result in incorrect operation of the OCS 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.
-
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 reset.
-
Make sure the voltage to the OCSM is greater than 8 volts and less than 18 volts.
-
Make sure the OCS is not below 6º C (42.8º F) or above 36º C (96.7º F) when initiating the OCS
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 reset process.
-
Prior to carrying out the OCS 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.
