This procedure replaces the passenger airbag module in the dashboard of a 2014-2019 Toyota Corolla, requiring dashboard panel removal and proper handling of the SRS system.

Warnings

Tools required

Parts

• Passenger airbag module × 1 — Use OEM Toyota airbag module for your specific model year
• Dashboard trim clips (if damaged) × 1 — Toyota OEM dashboard clips

Preparation

1. Park vehicle on level ground and engage parking brake
2. Turn ignition OFF and remove key from vehicle
3. Disconnect negative battery terminal and secure cable away from terminal
4. Wait a MINIMUM of 2 minutes for SRS system capacitors to fully discharge
5. Ensure you have the correct replacement airbag module for your specific model year and trim level
6. Place protective covering over steering wheel and seats to prevent damage during work
7. Position new airbag module in a safe location with deployment side facing UP, away from work area

Procedure

1. 1

   Remove glove box assembly
   Open the glove box fully. Locate and remove the damper arm on the right side by squeezing it to release. Squeeze both sides of the glove box inward to release the stops from the dashboard opening, then pull the glove box completely out to access the back panel. Disconnect any glove box light connectors if equipped.
2. 2

   Access passenger airbag mounting area
   With the glove box removed, you now have access to the passenger airbag mounting bolts from below. Use a flashlight to locate the airbag module behind the upper dashboard. Identify the electrical connector(s) attached to the airbag module - typically a yellow SRS connector with a locking tab.
3. 3

   Disconnect airbag electrical connector
   Locate the yellow SRS connector on the back of the airbag module. Press the locking tab and carefully disconnect the connector. DO NOT pull on wires - grasp the connector body. The connector may have a secondary lock that must be released first. Mark or photograph connector orientation for reassembly.
   ⚠️Ensure the battery has been disconnected for at least 2 minutes before touching any SRS connectors. The connector carries deployment voltage when system is active.
4. 4

   Remove upper dashboard cover panel (if required)
   Some model years require removal of the upper dashboard cover to access the top airbag mounting bolts. Carefully pry up the defroster grille panels using trim tools. Remove any screws securing the upper dashboard panel (typically located under the removed grilles and at the windshield edge). Gently lift the panel forward and up to release clips.

5. 5

   Remove airbag module mounting bolts
   Locate the airbag module mounting bolts - typically 4 bolts securing the module to the dashboard frame (2 accessible from below through glove box opening, 2 from above if upper panel removed). Use the appropriate Torx bit (typically T30) to remove these bolts. Support the airbag module while removing the final bolt to prevent it from falling.
   ⚠Support the airbag module while removing the last mounting bolt. The module is heavy and can damage components or cause injury if dropped.

6. 6

   Remove old airbag module
   Carefully guide the old airbag module out through the glove box opening or from the top, depending on your model configuration. Move slowly to avoid snagging wires or damaging dashboard components. Place the old module on a stable surface with deployment side facing UP, away from any loose objects or metal surfaces.
   ⚠️Place the removed airbag module deployment side UP on a stable surface away from people and objects. Even a deployed airbag can contain residual explosive material.
7. 7

   Inspect mounting points and clean area
   Examine the dashboard mounting points for any damage, cracks, or stripped threads. Clean any debris from the mounting area. Verify that the mounting bracket is secure and all threaded holes are clean and undamaged. Check that no wiring has been damaged during the airbag deployment or removal process.
8. 8

   Position new airbag module
   Remove the new airbag module from its packaging only when ready to install. Verify it matches the old module exactly. Carefully position the new module into the dashboard opening, aligning the mounting holes with the dashboard frame. Ensure no wires are pinched or routed incorrectly.
   ⚠Handle new airbag module carefully - do not drop, strike, or expose to static discharge. Keep deployment side facing toward dashboard during installation.
9. 9

   Install airbag module mounting bolts
   Thread all mounting bolts by hand first to ensure proper alignment and prevent cross-threading. Once all bolts are hand-tight, use a calibrated torque wrench to tighten each bolt to exactly 7.0 Nm (5.0 lb-ft) in a cross-pattern sequence. This torque specification is CRITICAL for proper airbag deployment characteristics.
   ⚠️CRITICAL: Airbag mounting bolts MUST be torqued to exactly 7.0 Nm (5.0 lb-ft). Incorrect torque can affect deployment speed and angle, potentially causing injury.

10. 10

    Connect airbag electrical connector
    Align the yellow SRS connector with the airbag module connector, ensuring correct orientation. Push firmly until you hear and feel a positive click. Engage any secondary locking mechanism if present. Gently tug on the connector (not wires) to verify it is fully locked. Route the connector wire away from any sharp edges or pinch points.
    ⚠Ensure connector is fully locked with a positive click. A loose connection will trigger the SRS warning light and may prevent deployment.
11. 11

    Reinstall upper dashboard panel (if removed)
    If the upper dashboard panel was removed, position it back onto the dashboard frame. Ensure all alignment clips engage properly. Install cover screws and tighten to 10.0 Nm (8.0 lb-ft). Reinstall defroster grille panels by pressing firmly until clips engage.

    Cover Screws10 Nm (8 lb-ft)
12. 12

    Reinstall glove box assembly
    Reconnect any glove box lighting connectors if equipped. Position the glove box into the dashboard opening. Squeeze the sides and push past the stops until they click into place. Attach the damper arm to the right side of the glove box. Open and close the glove box several times to verify proper operation.
13. 13

    Reconnect battery and clear codes
    Reconnect the negative battery terminal and tighten the ground bolt to 13.0 Nm (10.0 lb-ft). Do not turn the ignition ON yet. The SRS warning light will illuminate when the ignition is turned on. This is normal and requires code clearing with a professional scan tool capable of SRS system diagnostics.
    ⚠After any SRS work, diagnostic codes must be cleared and the system must be verified with a professional scan tool. The vehicle should not be driven until this is completed.

    Ground Bolt13 Nm (10 lb-ft)

Reassembly

1. Verify all dashboard panels, covers, and trim pieces are properly secured and aligned
2. Ensure no tools or parts have been left in the dashboard cavity
3. Check that the glove box operates smoothly and the damper functions correctly
4. Confirm no loose wires or connectors are visible in the work area

Verification

• Turn ignition to ON position (do not start engine) - the SRS warning light should illuminate for approximately 6 seconds then extinguish. If it stays on, flashes, or does not illuminate, DO NOT operate the vehicle
• Use a professional-grade scan tool with SRS capabilities to read and clear any diagnostic trouble codes from the airbag control module
• Perform an SRS system verification test using the scan tool to confirm the new airbag module is communicating properly
• Verify the passenger airbag ON/OFF indicator (if equipped) functions correctly with and without weight on the passenger seat
• Document the installation with date, mileage, and part number for vehicle service records
• CRITICAL: If the SRS warning light remains illuminated or flashes after code clearing, or if any system verification test fails, DO NOT drive the vehicle - have it towed to a professional for diagnosis
• Test drive the vehicle and verify no warning lights appear and all dashboard components function normally
