Seat Cushion - Front, Passenger Side: Disassembly

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: To prevent system failure, it is necessary to carry out the Occupant Classification Sensor (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: Do not install a new heater mat on a front passenger seat cushion, it is not serviceable separately. If a new cushion heater mat is needed on the front passenger seat, an Occupant Classification Sensor (OCS) system service kit equipped with a heater mat must be installed. Failure to follow this instruction may result in incorrect operation of the OCS system. Refer to OCCUPANT CLASSIFICATION SENSOR -- SERVICE KIT for the OCS removal and installation procedure.

NOTE: Occupant Classification Sensor (OCS) system components, seat cushion foam pad, bladder with pressure sensor and Occupant Classification System Module (OCSM), are calibrated to each other and are serviced as an assembly. The OCS system components are not to be installed separately. If a new OCS system, OCS system component or seat cushion foam pad are needed, a new OCS system service kit (seat cushion foam pad, bladder with pressure sensor and OCSM ) must be installed as an assembly.

All seats

Remove the seat. For additional information, refer to SEAT - FRONT .
Remove the seat backrest. For additional information, refer to SEAT BACKREST - FRONT .
Remove the safety belt buckle pretensioner.
- Disconnect and detach the safety belt buckle pretensioner and buckle switch electrical connectors from the seat track.
- Detach the wiring harness pin-type retainer.
- Route the wiring harness from between the seat track and cushion frame.

NOTE: Note wiring harness routing for installation.

Detach the seat harness electrical connector and wiring harness from the seat track.
Remove the 4 seat track-to-cushion frame bolts.
If equipped, disconnect the heated seat system components.
- Disconnect and detach the cushion heater mat electrical connector.
- Release the locking tab and remove the heated seat relay from the bracket on the cushion frame.
- Disconnect the heated seat relay electrical connector.
Seat with original equipment Occupant Classification Sensor (OCS) system

WARNING: Install a new occupant classification sensor (OCS) system service kit as a complete assembly. Never install only part of the kit components. Failure to follow this instruction may result in incorrect operation of the OCS system and increases the risk of serious personal injury or death in a crash.

NOTE: To identify between a production OCS system and a service OCS system ( OCS service kit), inspect the electrical connector. A production OCS system allows the disconnect of the OCSM electrical connector. A service OCS system (OCS service kit) has the electrical connector glued to the OCSM . It cannot and should not be disconnected or altered.

Disconnect the electrical connectors and wiring clips.
1. Disconnect the OCSM electrical connector.
2. Disconnect the pressure sensor electrical connector.
  - Detach the wiring harness retainers and wiring harness from the cushion frame.
