Handle both the sensor and the passenger seat assembly gently, as damaging them could result in calibration problems and you must not put any weight on the seat when it is removed for installation. Should a sensor fall or break, put in a new unit and if the seat has been dropped with the weight sensors out, change all of them. After you've taken out or released the passenger side front seat assembly, use a diagnostic scan tool and the Occupant Classification Seat Weight special tool to complete the Occupant Classification System Verification Test. Keep the sensor stud bolt in position using alignment tool 9689 when you install the nut into the seat adjuster riser and make sure to use hand tools for any sensor fastener service. Fit the weight sensor onto the adjuster track and fasten it with nuts tightened to 21 ft. lbs. (28 Nm), after that attach the seat track to the riser and fasten a nut on each center stud for every weight sensor, making sure you don't tighten a center nut without the tool for straining the sensor. Place the fork into the weight sensor hole and seat the support yoke against the weight sensor cage, fasten the nut until it reaches 45 Nm (33 ft. lbs.) for all sensors and snap each weight sensor connection into place after the passenger front seat is installed. Be sure not to link the negative
Battery Cable until you finish the system test and after the status of the air bag Verification test shows OK, use the diagnostic scan tool and Occupant Classification Seat Weight tool 9077 to confirm the Occupant Classification System test.
