Seat Cushion - Front: Assembly
All seats
- Position the cushion trim cover to the cushion foam pad, attach the hook-and-loop strips and install the hog rings.
- Route the seat wire harness to the cushion frame and attach the pin-type retainer(s) as noted during removal.
- Position the OCS components and seat wire harness through the cushion frame opening as noted during removal.
- Feed the hose, pressure sensor, wire harness, electrical connectors and ECU through the opening in the cushion frame.
- Install the OCS bladder pin-type retainers.
- Position the ECU onto the seat cushion pan bracket and install the new rivets.
- The ECU must be correctly positioned and securely riveted in place. Failure to do so can set a diagnostic trouble code (DTC) in the restraints control module (RCM).
- Bend the retaining tab back on the pressure sensor bracket.
- Install the pressure sensor onto the cushion frame bracket, making sure the retaining tab is completely engaged.
- When installed correctly, an audible click will be heard and the pressure sensor will not be able to be removed from its bracket without disengaging the retaining tab.
- Attach any seat wire harness routing pin-type retainers to the cushion frame as noted during removal.
- Install the seat control switch and the lumbar control switch into the cushion side shield.
- Install the seat control switch knob.
- Position the cushion side shield to the cushion frame and connect the seat control switch and lumbar control switch.
- Position the cushion foam pad and trim cover to the cushion frame.
- Install the seat track. For additional information, refer to Seat Track - Manual or Seat Track - Power .
- Install the seat backrest. For additional information, refer to Seat Backrest - Front .
- Install the seat. For additional information, refer to Seat - Front .
- Repower the SRS. If the passenger seat has been serviced, do not prove out the SRS at this time. For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures portion of SUPPLEMENTAL RESTRAINT SYSTEM .
- Make sure the OCS system components are connected and no faults are present.
- Make sure the OCS system is not at a temperature below 0°C (32°F) or above 45°C (113°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, 0°C to 45°C (32°F to 113°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 OCS system reset process.
- Carry out the OCS system reset active command using the scan tool.
- With the front passenger seat empty, use a scan tool to trigger the active command.
- Cycle the ignition switch from ON to OFF.
- 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 visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately 6 seconds and then turn off. If an air bag SRS fault is present, the air bag 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 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 indicator and any SRS fault discovered must be diagnosed and repaired.
Clear all continuous DTCs from the RCM using a scan tool.

Passenger seats with OE OCS or OCS service kit
WARNING:
Do not separate components.
CAUTION:
Inspect the occupant classification sensor assembly, seat cushion frame and support assembly for any foreign material, before installing the occupant classification sensor assembly to the seat cushion frame. If any foreign material is found, remove it. Failure to do so may result in personal injury, in the event of an air bag deployment.
CAUTION:
Failure to route the seat occupant sensor components through the correct seat cushion support opening can cause component failure.
CAUTION:
While positioning the seat cushion frame and occupant classification sensor assembly, be careful not to damage any of the components. Failure to do so can result in component failure.
NOTE:
If the original equipment occupant classification sensor (OCS) is not being installed, install a service kit OCS using all parts in the kit.

All seats
Passenger seats with OE OCS or OCS service kit
WARNING:
Do not separate the occupant classification sensor (OCS) system components.
CAUTION:
It is necessary to carry out the occupant classification sensor (OCS) system reset when a front passenger seat backrest is separated from the seat cushion, the seat cushion is disassembled, a new trim cover is installed or an OCS service kit is installed. A scan tool is used to trigger the active command to carry out the OCS system reset.
CAUTION:
Make sure the seat is completely assembled before carrying out the OCS system reset.
CAUTION:
The following precautions must be taken before carrying out the OCS system reset.
NOTE:
For best results, the OCS system should be at or near room temperature, 10°C to 29°C (50°F to 85°F).
NOTE:
If the first attempt to carry out the OCS system reset is unsuccessful, a second attempt must be made.
NOTE:
The ignition switch must be cycled after carrying out the OCS system reset.
