F 150 4WD Pickup V8-5.4L VIN V Flex Fuel (2006)
Passenger Seat Cushion (Part 2)
Disassembly and Assembly
WARNING:
-
The safety belt pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when
handling a safety belt buckle pretensioner or safety belt retractor pretensioner. Never probe a pretensioner electrical connector. Doing so
could result in pretensioner or air bag deployment and could result in personal injury.
-
To reduce the risk of personal injury, do not use any memory saver devices.
CAUTION: It is necessary to rezero the occupant classification sensor (OCS) system when a front passenger seat cushion is disassembled, a
new trim cover is installed, or an OCS service kit is installed. A diagnostic tool is used to trigger the active command to carry out rezeroing of
the OCS system.
NOTE:
-
OCS system components (seat wiring harness, seat cushion frame, seat cushion foam pad, bladder with pressure sensor and electronic control unit
[ECU]) are calibrated to each other and are serviced as an assembly. 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 frame, seat cushion foam pad,
bladder with pressure sensor, seat wiring harness and ECU must be installed as an assembly.
-
To identify between a production OCS system and a service OCS system (OCS service kit) inspect the ECU electrical connector. A production
OCS system allows the disconnect of the ECU electrical connector. A service OCS system (OCS service kit) has the ECU electrical connector
glued to the ECU. It cannot and should not be disconnected or altered.
-
Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic
procedure again.
-
When installing a new OCS service kit, refer to Air Bag Systems for the OCS removal and installation procedure.
-
If a seat equipped with a supplemental restraint system (SRS) component is being serviced, the SRS must be depowered.
-
The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate
a supplemental restraint system (SRS) fault.
-
The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
-
For vehicles with power seats, position the seat cushion to its lower position before disconnecting the power seat.
-
Power seat shown, manual seat similar.
All seats
1. Remove the seat and depower the SRS.
2. If equipped, disconnect the power seat switch electrical connector.
