Removal And Installation: Installation
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.
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).
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.
- Carefully inspect the ODS to be certain that it is in good condition.
- If the removed ODS sensor is being reused, apply a spray adhesive for plastics to the adhesive area after providing suitable protection from overspray to the remaining portions of the sensor mat.
- If a new ODS is being used, remove the release paper from the adhesive patch of the ODS mat.NOTE:
The release paper should not be removed from the adhesive patch of a new ODS mat until just prior to application to the seat cushion foam.
- If the seat cushion foam is being reused, apply a spray adhesive for plastics to the adhesive area after providing suitable protection from overspray to the remaining portions of the seat cushion foam.
- If a new seat cushion foam is being used, remove the release paper from the adhesive area of the seat cushion foam.NOTE:
The release paper should not be removed from the adhesive area of a new seat cushion foam until just prior to application of the ODS mat.
- Insert the ODS pigtail wire harness and the tail of the ODS through the clearance hole in the seat cushion foam.
- Carefully position and center the ODS mat onto the seat cushion foam with the adhesive patch of the mat centered over the adhesive area of the seat cushion foam.
- Apply hand pressure (0.8 bar or 12 psi) over the adhesive patch of the ODS for at least four seconds to activate and adhere the adhesive to the seat cushion foam.
- Reach under the back of the front seat cushion frame to access and route the ODS pigtail wire and connector.
- Install the seat back onto the seat cushion. Refer to SEAT BACK, FRONT, REMOVAL AND INSTALLATION or SEAT BACK, REAR, REMOVAL AND INSTALLATION .
- Install the trim onto the front seat cushion foam and frame. Refer to COVER, SEAT CUSHION, FRONT, REMOVAL AND INSTALLATION .
- Connect the seat wire harness connections under the seat cushion for the seat track position sensor (2a) and the ODS (2b).
- Engage the seat wire harness retainers (1a, 1b and 1c).
- Install the passenger side front seat into the vehicle. Refer to SEAT, FRONT, REMOVAL AND INSTALLATION .
- Connect the negative battery cable.
