This procedure covers the replacement of a heated seat module on a 2012-2017 Toyota Camry with the 2.5L I4 engine, including removal of the seat and accessing the module beneath the seat cushion.

Warnings

Tools required

Parts

• Heated seat module × 1 — Use OEM specification
• Seat wire harness (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Ensure ignition is off and key is removed from vehicle
3. Disconnect negative battery terminal and wait 90 seconds minimum
4. Move seat fully forward to access rear mounting bolts, then fully rearward to access front bolts during removal
5. Take photos of electrical connector orientations before disconnecting

Procedure

1. 1

   Remove seat track covers
   Locate the plastic covers on the inner and outer seat tracks at the front and rear of the seat. Use a flathead screwdriver or trim tool to carefully pry up these covers to expose the seat mounting bolts underneath. There are typically four covers total (front inner, front outer, rear inner, rear outer).
2. 2

   Remove rear seat mounting bolts
   With the seat moved fully forward, use a 12mm socket to remove the two rear seat mounting bolts (one on the inner track, one on the outer track). Support the rear of the seat as you remove the last bolt.
   ⚠Seat is heavy - consider having an assistant help support it during removal

3. 3

   Remove front seat mounting bolts
   Slide the seat fully rearward. Use a 12mm socket to remove the two front seat mounting bolts (one on the inner track, one on the outer track). Keep track of any washers or spacers on the bolts.

4. 4

   Disconnect electrical connectors
   Tilt the seat backward slightly to access the underside. Locate all electrical connectors beneath the seat including the heated seat connector, seat position sensor, and any airbag connectors (usually yellow). Press the release tabs and carefully disconnect all connectors. Note the routing of the wiring harness.
   ⚠Yellow connectors are airbag-related - ensure battery has been disconnected for at least 90 seconds
5. 5

   Remove seat from vehicle
   With all electrical connections disconnected, carefully lift the seat assembly out of the vehicle. The seat weighs approximately 40-50 lbs depending on options. Place the seat on a clean, padded work surface with the bottom facing up.
6. 6

   Access heated seat module
   With the seat inverted, locate the heated seat module attached to the seat frame beneath the seat cushion. It is typically a rectangular control unit with a multi-pin connector. On some models, you may need to remove a protective fabric cover secured with plastic clips to access the module.
7. 7

   Disconnect heated seat module connector
   Press the release tab on the heated seat module connector and carefully pull it straight off the module. Inspect the connector pins for corrosion or damage. Check the heating element connectors at the module for proper seating.
8. 8

   Remove heated seat module mounting bolts
   Using a 10mm socket, remove the mounting bolts securing the heated seat module to the seat frame. There are typically 2-3 bolts depending on the module design. Note the orientation and position of the module for proper reinstallation.

9. 9

   Remove old module and install new module
   Remove the old heated seat module from the seat frame. Position the new module in the exact same orientation and location. Ensure any grounding tabs or contact points are clean and making proper contact with the seat frame. Install the mounting bolts finger-tight initially.
10. 10

    Torque module mounting bolts
    Using a torque wrench, tighten the heated seat module mounting bolts to specification in a cross pattern if multiple bolts are present. Verify the module is seated flush against the mounting surface.

11. 11

    Reconnect heated seat module connector
    Plug the heated seat module connector firmly into the new module until you hear or feel a positive click. Gently tug on the connector to verify it is fully locked. Reinstall any protective covers that were removed.
12. 12

    Reinstall seat in vehicle
    Carefully lift the seat assembly and position it over the mounting points in the vehicle. Align the seat track bolt holes with the floor mounting points. Reconnect all electrical connectors in the reverse order of removal, ensuring each connector clicks securely into place.
13. 13

    Install and torque seat mounting bolts
    Install all four seat mounting bolts (front inner, front outer, rear inner, rear outer) and tighten them in a cross pattern. Use a torque wrench to tighten each bolt to specification. Double-check that all bolts are secure and the seat does not move on its mounts.
    ⚠Properly torqued seat bolts are critical for occupant safety in a collision

14. 14

    Reinstall seat track covers
    Press the plastic seat track covers back into place over each mounting bolt location. Ensure they are fully seated and flush with the track housing.
15. 15

    Reconnect battery and test system
    Reconnect the negative battery terminal and torque to specification. Turn the ignition to the ON position (do not start engine). Test the heated seat function by pressing the heated seat button and verifying the indicator light illuminates. Allow the seat to heat for 2-3 minutes and verify warmth is felt in the seat cushion.

Reassembly

1. Ensure all electrical connectors are fully seated and locked
2. Verify seat slides smoothly on tracks and all adjustment functions work properly
3. Confirm no tools or parts are left under or around the seat
4. Test seat belt function and ensure nothing interferes with seat belt operation

Verification

• Start the vehicle and verify no airbag warning lights are illuminated on the dashboard
• Test heated seat on all heat settings (low, medium, high if applicable) and verify proper operation
• Verify seat adjustment functions work correctly (fore/aft, recline, height if equipped)
• Check that seat is firmly mounted with no movement or play at the mounting points
• Confirm no unusual noises when moving the seat through its full range of motion
