Occupant Detection Sensor - Installation
INSTALLATION
WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, 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 SRS. Failure to take the proper precautions could result in accidental airbag deployment.
CAUTION: When handling a new Occupant Detection Sensor (ODS), it should never be bent, creased, torn, cut or abraded. The ODS should not be handled with or come into contact with hard or sharp-edged tools or objects. Do not allow the ODS to drop more than 2 meters (6.5 feet). Prior to installation, do not sit on, stand on or place boxes, tools or any other foreign object on the ODS. If the ODS adhesive patches become inadvertently adhered to any seat materials or foreign objects prior to proper positioning on the seat cushion, the ODS must be scrapped and replaced with a new unit. Do not modify the seat foam or trim materials of a seat that contains an ODS. Failure to observe these cautions may result in an inoperative ODS, or an ODS that provides inaccurate inputs to the Occupant Restraint Controller (ORC).
1. Except on vehicles equipped with the ventilated seat option, insert the locator tab of the Occupant Detection Sensor (ODS) mat (1) into the locator hole (2) near the center of the seat cushion foam (4) and push the tab all the way through the foam. On vehicles with the ventilated seat option, leave the locator tab flat on the seat cushion and pointed forward in the vehicle.
2. Position the sensor mat on the seat cushion with the two mat sensor cell branches aligned with the sides of the seat and the rear edge of the mat positioned 124 millimeters (4.88 inches) (Distance A) rearward from the back edge of the forward crimp channel in the seat cushion foam.
CAUTION: The adhesive used to secure the ODS to the seat is heat activated and requires that both the adhesive and the material it is applied to be ideally between 21° and 38° C (between 70° and 100° F). Application of the ODS to surfaces below 10° C (50° F) is not recommended as the adhesive becomes too firm to readily adhere. Do not touch or allow the adhesive patches to contact any foreign materials with the release paper removed. Do not attempt to add adhesive materials to the ODS.
3. Peel the release paper off of the adhesive patch (3) on the underside of the ODS mat.
4. Apply hand pressure (0.8 bar or 12 psi) over the adhesive patch of the ODS mat for at least four seconds to activate and adhere the adhesive to the seat cushion foam.
5. Route the ODS pigtail wires through the clearance hole (5) near the back of the seat cushion foam and insert the hot melt block into the recess.
6. Reach under the back of the front seat cushion frame to access, route and reconnect the ODS pigtail wire and connector to the seat wire harness.
7. If the vehicle is so equipped, reinstall the heater mat onto the seat cushion foam. Heater Pad - Installation.
8. Reinstall the trim onto the front seat cushion foam and frame. Seat Cushion Cover - Installation.
9. Reinstall the passenger side front seat into the vehicle. Front Seat - Installation.
10. Reconnect the battery negative cable.
