INSTALLATION

WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the supplemental restraint system before attempting any steering wheel, steering column, airbag, occupant classification system, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the proper precautions could result in accidental airbag deployment.

WARNING: To avoid serious or fatal injury on vehicles equipped with the Occupant Classification System (OCS), do not modify the front passenger seat assembly or center floor console in any way. Do not use any prior year, subsequent year, secondary or aftermarket seat trim covers. At no time should any Supplemental Restraint System (SRS) or OCS component be modified or replaced with any part except those which are specified for the particular vehicle application in the DaimlerChrysler Mopar Parts Catalog. Failure to observe these precautions could cause an OCS miscalibration condition, which may result in the passenger airbag failing to deploy when required or deploying when not required.

WARNING: To avoid serious or fatal injury, never strike or drop a seat weight sensor or the passenger side front seat assembly to which the sensors are secured as it can damage the sensors or affect their calibration. The seat weight sensors and the passenger side front seat assembly must be handled with care to avoid damage to the sensors. Do not sit upon or place any loads upon a passenger side front seat while it is removed from its mounts in or outside of the vehicle. If an individual sensor is dropped or damaged, replace the sensor with a new and unused unit. If a seat has been dropped during removal or loaded while removed from its mounts, replace each of the seat weight sensors with new and unused units. Failure to observe this warning could result in an accidental, incomplete, or improper passenger side front supplemental restraint deployment.

WARNING: To avoid serious or fatal injury on vehicles equipped with the Occupant Classification System (OCS), any time the passenger side front seat assembly has been removed or loosened from the vehicle for service of any vehicle component or system the Occupant Classification System Verification Test must be performed using a diagnostic scan tool and the Occupant Classification Seat Weight special tool following reinstallation. Refer to the appropriate diagnostic procedures. Failure to observe this warning could result in an accidental, incomplete, or improper passenger side front supplemental restraint deployment.




1. Position the seat weight sensor (2) over the studs on the lower track of the passenger side front seat adjuster (1).
2. Install and tighten the two nuts (3) that secure the sensor to the studs. Tighten the nuts to 28 Nm (21 ft. lbs.).
3. Carefully position the seat track risers (5) over all four seat weight sensor studs.

CAUTION: A strain gauge alignment tool (Special Tool No. 9689) (2) must be used to secure the body of the seat weight sensor (1) from any rotation during removal or installation of the nut that secures the sensor stud to the seat track riser. In addition, the sensor fasteners should always be serviced using hand tools ONLY, and not electric or pneumatic power tools. Failure to observe these cautions may result in irreversible sensor damage requiring sensor replacement.




4. Install the strain gauge alignment tool (Special Tool 9689) on the sensors by inserting the center fork (1) of the tool between the flats on each side of the sensor body and inside of the cage, then seating the tool support yoke (2) firmly against the outside of the sensor cage.
5. With the alignment tool securing the body of the seat weight sensor, install and tighten the nut that secures the sensor stud to the seat track riser. Tighten the nut to 45 Nm (33 ft. lbs.).
6. Transfer the special tool to each weight sensor, one at a time, then install and tighten the nuts that secure each of the four sensor studs to the seat track risers until all four nuts have been installed and tightened.
7. From the underside of the seat, reconnect the seat wire harness to the connector receptacle of the seat track position sensor located on the inboard side of the inboard seat adjuster upper track near the rear of the seat track.
8. Reconnect the seat wire harness to the connector receptacles of each of the four weight sensors.
9. Reinstall the passenger side front seat into the vehicle. (Refer to 23 - BODY/SEATS/SEAT - INSTALLATION).
10. Do not reconnect the battery negative cable at this time. The supplemental restraint system verification test procedure should be performed following service of any supplemental restraint system component. (Refer to 8 - ELECTRICAL/RESTRAINTS - STANDARD PROCEDURE - VERIFICATION TEST).
11. Following successful completion of the supplemental restraint system verification test procedure, perform the Occupant Classification System Verification Test using a diagnostic scan tool and the Occupant Classification Seat Weight special tool. Refer to the appropriate diagnostic procedures.
