Occupant Classification System (OCS) Sensor: Installation
WARNING: This page is about a different car, the 2016 Ford Transit Connect. However, it is still accessible from the selected car via links, so may be relevant.
- 3.NOTE: The service part includes the seat cushion, the heater mat (if equipped) and the occupant classification sensor.
- 1.NOTE: Make sure that no components catch.
Install the OCS with the cushion cover.
- 2.NOTE: Make sure that the component is installed to the position noted before removal.
Route the OCS sensor hose and heater mat pigtail (if equipped) through the seat cushion support wires.

- 4.NOTE: Make sure that the components are installed to the position noted before removal.
- 1.
Attach the OCS sensor to the bracket.
- 2.
Connect the OCS electrical connector.

- 5.WARNING: 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.
- 6.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 OCS and increases the risk of serious personal injury or death in a crash.
- 7.NOTE: To prevent system failure, take the following precautions before carrying out the OCS reset.
- Make sure the voltage to the OCS module is greater than 8 volts and less than 18 volts.
- Make sure the OCS is not below 42.8 °F (6 °C) or above 96.7 °F (36 °C) 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 42.8 °F (6 °C) to 96.7 °F (36 °C) 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.
- 8.
Using a diagnostic scan tool, carry out the OCS reset. Cycle the ignition switch after the OCS reset.
- 10.
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.
- 11.
Carry out a second OCS reset. If the second attempt is unsuccessful, install a new OCS service kit. Refer to: Occupant Classification System (OCS) Sensor .

Prove out the SRS by turning the ignition from ON to OFF. Wait 10 seconds, then turn the ignition back to ON and monitor the airbag warning indicator with the airbags installed. The airbag warning indicator illuminates continuously for approximately 6 seconds and then turns off. If a SRS fault is present, the airbag warning indicator will fail to light, remain lit continuously, or flash.
- 13.
The flashing might not occur until approximately 30 seconds after the ignition has been turned from OFF to ON. This is the time required for the RCM to complete the testing of the SRS. If the airbag warning indicator is inoperative and a SRS fault exists, a chime sounds in a pattern of 5 sets of 5 beeps. If this occurs, diagnose and repair the airbag warning indicator and any SRS faults.
