Remove and replace the airbag control module (ACM) located under the center console, including proper disarming procedures and system reprogramming requirements.

Warnings

Tools required

Parts

• Airbag Control Module (ACM) × 1 — Use OEM specification - must be programmed to VIN

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition to OFF position and remove key
3. Disconnect negative battery terminal first, then positive terminal
4. Wait minimum 2 minutes for airbag system capacitors to fully discharge before proceeding
5. Ensure seat is moved fully rearward for access to center console
6. Verify replacement module part number matches original and is compatible with vehicle VIN

Procedure

1. 1

   Remove center console trim panels
   Remove the front floor console bezel by gently prying upward starting at the rear edge. Disconnect any electrical connectors for power outlets or switches. Remove the cupholder insert by lifting straight up. Remove the gear shifter trim ring by pulling upward carefully.
2. 2

   Access console mounting fasteners
   Locate and remove the console mounting screws. There are typically 4-6 screws located under the trim pieces just removed. Some screws may be hidden under rubber mats or in cupholder area. Remove all fasteners completely.

3. 3

   Remove center console assembly
   Carefully lift the rear portion of the console upward. Disconnect any remaining electrical connectors for lights, power outlets, or other accessories. Slide console rearward and upward to remove from vehicle. Set aside in safe location to avoid damage.
   ⚠Console may have sharp edges or hidden clips. Use care when removing to avoid injury or breaking clips.
4. 4

   Locate airbag control module
   The ACM is mounted on the transmission tunnel, typically near the center of the vehicle under where the console was located. It is a rectangular metal box with a large yellow connector. Identify the module and verify it is the correct component before removal.
5. 5

   Disconnect ACM electrical connector
   Locate the yellow airbag connector (may have orange or yellow locking tab). Press the locking tab and carefully pull connector straight out from module. Do not twist or bend connector. Inspect connector pins for damage or corrosion.
   ⚠️Ensure battery has been disconnected for at least 2 minutes before touching any airbag connectors. Never connect or disconnect with power applied.
6. 6

   Remove ACM ground connection
   Locate the ground strap attached to the module mounting bracket or nearby body point. Remove the ground strap bolt using appropriate socket. Clean ground connection point with wire brush to ensure bright metal contact for reinstallation.
   ⚠Clean ground connections are critical for proper ACM operation. Ensure contact surfaces are free of paint, rust, and corrosion.

   Ground Strap Bolts12 Nm (9 lb-ft)
7. 7

   Remove ACM mounting bolts
   Remove the module mounting bolts securing the ACM to the bracket or transmission tunnel. There are typically 2-4 bolts. Keep bolts organized for reinstallation. Carefully remove module from mounting location.
   ℹ️Handle old module carefully even though it is being replaced. Store in safe location away from work area.

8. 8

   Inspect mounting area and connectors
   Thoroughly inspect the mounting bracket for damage or corrosion. Check wiring harness and connector for signs of damage, corrosion, or water intrusion. Clean mounting surface and ground points with wire brush. Verify connector pins are straight and clean.
9. 9

   Install new ACM
   Remove new module from anti-static packaging only when ready to install. Position new ACM on mounting bracket in same orientation as original. Install mounting bolts and torque to specification. Ensure module is seated fully against mounting surface.
   ⚠Do not touch connector pins or circuit board components. Handle module by housing only.

    Reconnect ground connection
    Install ground strap to cleaned ground connection point. Ensure metal-to-metal contact with no paint or corrosion between surfaces. Torque ground strap bolt to specification. Verify connection is secure.

11. 11

    Connect ACM electrical connector
    Carefully align yellow airbag connector with module. Push connector straight onto module until locking tab clicks into place. Verify connector is fully seated and locked. Gently pull on connector to confirm it is secure.
12. 12

    Reinstall center console
    Position console back into vehicle, routing any wiring through appropriate openings. Reconnect all electrical connectors for power outlets, lights, and switches. Install console mounting screws and torque to specification. Reinstall trim panels, cupholder, and shifter trim ring.

    Cover Screws15 Nm (11 lb-ft)
13. 13

    Reconnect battery
    Reconnect positive battery terminal first, then negative terminal. Torque battery terminal bolts to specification. Do not overtighten as this can damage terminals.
    ⚠Battery terminal bolts require only 6 Nm (4 lb-ft). Overtightening will strip threads or crack terminal.

    Program and verify ACM
    Connect factory-level diagnostic scan tool. Program new ACM with vehicle VIN and configuration data. This step is mandatory and cannot be skipped. Clear all airbag fault codes. Perform system self-test according to scan tool prompts. Verify all airbag system components communicate properly.
    ⚠️Module programming is mandatory for proper airbag system operation. Unprogrammed module will not deploy airbags in a collision.

Reassembly

1. Verify all console trim panels are properly clipped and secured
2. Ensure all electrical connectors under console are reconnected
3. Confirm no tools or parts are left in vehicle interior
4. Test all console functions (power outlets, lights, shifter operation)

Verification

• Turn ignition to ON position without starting engine - airbag warning light should illuminate for 6-8 seconds then turn OFF
• If airbag light stays on, flashes, or does not illuminate, system has fault and requires further diagnosis
• Use scan tool to verify no active airbag fault codes are present
• Verify all airbag components show 'Active' or 'Present' status in scan tool
• Test drive vehicle and confirm airbag warning light remains OFF
• Document module serial number and programming date for vehicle records
• Recommend professional verification if any concerns about system operation exist
