The rear seat outer belt assembly functions by multiple crucial components which guarantee operational safety. The safety standards require regular checks with proper maintenance of these components to ensure proper operation. A quick response to all signs of wear or damage will help keep the seat belt system in impeccable condition.

A seat belt pretensioner installation requires the activation of the device through the specified Special Service Tool: 09082-00770. An operational check of the tool requires clip attachment to the positive terminal of the battery using a red clip and the negative terminal with a black clip without connecting the yellow connector. When testing the activation switch you should observe the LED light up only upon switch pressing and if it activates without pressure from your hand you need to replace the tool. First disconnect the pretensioner connector which then requires removal of the rear seat cushion and seatback as well as front door scuff plate and No. 1 side trim and center pillar garnish before separating the pretensioner connector. Connect the Air Bag Deployment Tool: 09082-00700, 09082-00770 to the seat belt pretensioner by mounting the floor anchor of the seat belt before activation. A minimum distance of 10 m separates the tool from the vehicle where all vehicle doors must be secured and the tool needs battery power. Before activating the pretensioner through the switch confirm that both the vehicle and all occupants and bystanders are beyond 10 m of distance. Keep the active front seat outer belt untouched for thirty minutes since it will remain hot while using both gloves and safety glasses. The front seat outer belt needs to be placed in a plastic bag before tightening the bag for disposal. To dispose of the front seat outer seatbelt absence from vehicles, tension the belt with its retractor then trim it 100 mm from the retractor before proceeding with tool activation while executing safety measures diligently.

Disconnect the battery's negative (-) terminal cable.

Remove the bolt and anchor part of the outer belt, the rear seat shoulder belt guide center, the rear seatback board sub-assembly RH, the rear seat shoulder belt cover RH, and finally, the 4 nuts and outer belt.

A thorough understanding of the components of the seat belt assembly is required.

Disconnect the cable from the negative battery terminal and wait at least 90 seconds to prevent airbag and seat belt pretensioner activation.

Take out the 3 bolts and the outer belt.

Carefully disconnect the pretensioner connector, remove the bolt and floor anchor, and take out the 3 bolts and outer belt.
