Ford Focus Service Manual: Seat Cushion Cover - Front

Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool

Removal

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 carrying out the System Reset. 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, it is necessary to carry out the Occupant Classification System (OCS) system reset when a front passenger seat cushion is disassembled, a new trim cover installed or an OCS system service kit is installed. A scan tool is used to carry out the OCS system reset command.

NOTE:

For removal and installation of the OCS and Occupant Classification System Module (OCSM) on a front passenger seat, refer to Occupant Classification Sensor in Section  501-20B.

NOTE:

For component identification and locations, refer to Seat — Exploded View, Front in this section.

Passenger seat

1. 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 carrying out the System Reset. 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.

   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.

   NOTICE: To prevent system failure, the following precautions must be taken before carrying out the Occupant Classification System (OCS) system reset:

   • Make sure the voltage to the Occupant Classification System Module (OCSM) is above 8 volts and less than 18 volts.
   • Make sure the OCS system is not at a temperature below 6°C (42°F) or above 36°C (97°F) when initiating the OCS 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 within the limits, 6°C to 36°C (42°F to 97°F) for a minimum of 30 minutes.
   • Make sure nothing is present on the passenger seat before carrying out the OCS system reset and nothing is placed on the seat during the process.
   • Make sure a minimum 8-second time period has passed after cycling the ignition switch ON before the carrying out the OCS system reset process.

   Carry out the OCS system reset.

1. If the first system reset attempt was unsuccessful, carry out a thorough visual inspection of the following and repair any concerns found.
   • OCS system connector and wiring for damage
   • Pressure sensor hose for kinks and/or damage
   • Seat-related wiring harness and body wiring harness terminals and connectors for damage

1. NOTE:

   The ignition must be cycled after the OCS system reset.

   Carry out a second OCS system reset. If the second attempt is unsuccessful, install a new OCS system service kit. For additional information, refer to Occupant Classification Sensor in Section  501-20B.

All seats

1. Prove out the SRS as follows: Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and monitor the air bag warning indicator with the air bag modules installed. The air bag warning indicator will light continuously for approximately 6 seconds and then turn off. If an air bag SRS fault is detected, the air bag warning indicator will:
   - fail to light.
   - remain lit continuously. - flash.
   The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the Restraints Control Module (RCM) to complete the testing of the SRS . If the air bag warning indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of 5 sets of 5 beeps. If this occurs, the air bag warning indicator and any SRS fault discovered must be diagnosed and repaired. Clear all continuous DTCs from the RCM and OCSM using a scan tool.
