This procedure covers the removal and replacement of the airbag control module (ACM/RCM) located under the center console, including proper disarming and system reactivation.
Warnings
⚠️AIRBAG SYSTEM: Incorrect procedures can cause accidental airbag deployment resulting in serious injury or death. If you are not completely confident in your ability, seek professional service.
⚠️Wait a minimum of 2 MINUTES after disconnecting battery before touching any airbag components. Backup power must fully discharge.
⚠️Never probe airbag connectors with test equipment while connected. Always disconnect before testing.
⚠The airbag module must be programmed and configured to match your specific vehicle VIN and options. A Ford IDS tool or equivalent professional scan tool is required.
⚠Radio and clock presets will be lost when battery is disconnected. Record settings before starting.
⚠This procedure requires clearing crash data and verifying system integrity after installation. Improper completion may leave airbags non-functional.

Parts
- Airbag control module (RCM) × 1 — Use OEM Ford part number specific to vehicle build date
- Module mounting bolts (if corroded) × 2 — M8 x 1.25 x 20mm
Preparation
- Park vehicle on level surface, place transmission in Park, and engage parking brake
- Turn ignition to OFF position and remove key
- Record radio presets and clock settings
- Disconnect negative battery terminal, then disconnect positive battery terminal
- Wait minimum 2 MINUTES for airbag backup power to discharge completely
- Ensure all airbag warning labels and connectors show no signs of previous deployment (burn marks, connector damage)
Procedure
- 1Remove center console front sectionRemove the rubber mat from the front console cup holder area. Locate and remove the two 7mm screws at the front base of the console. Carefully pull the front console section upward and toward the rear to release the retaining clips. Disconnect any electrical connectors for power outlets or USB ports.
- 2Remove center console rear sectionOpen the center console lid and locate the two 8mm bolts inside the storage bin. Remove these bolts. Lift the rear console section upward to release clips. Disconnect any wiring connectors for rear power outlets or armrest lighting. Remove the entire rear console section from vehicle.
- 3Access airbag control moduleThe airbag control module is located on the transmission tunnel beneath where the center console was mounted, typically on the driver's side. Remove any foam or carpet covering the module. The module is a silver or black rectangular box approximately 4x6 inches with multiple wire harness connectors.
- 4Disconnect airbag module connectorsIdentify all connectors attached to the airbag module (typically 2-4 large connectors). Each connector has a secondary locking tab that must be released first. Slide the red or orange secondary lock tab away from the connector body. Then press the primary release tab while pulling the connector straight off. Never twist or rock connectors. Label each connector position if needed.
- 5Disconnect ground connectionLocate the ground wire attached to the module mounting bracket or nearby body panel. This is typically a black wire with a ring terminal secured by a bolt. Remove the ground bolt and carefully detach the ground connection. Inspect the ground connection point and clean if corrosion is present using a wire brush.Torque specGround Bolt17 Nm (13 lb-ft)
- 6Remove airbag module mounting boltsRemove the module mounting bolts securing the airbag control module to the transmission tunnel bracket. There are typically two bolts. Keep track of any spacers or washers between the module and mounting surface. Carefully remove the module from the vehicle.Torque specModule Mounting Bolts8 Nm (6 lb-ft)
- 7Inspect mounting area and connectorsBefore installing the new module, inspect all connector pins for damage, corrosion, or bent terminals. Check the mounting surface for corrosion or damage. Inspect all wiring harnesses for chafing, damage, or signs of previous deployment (melted insulation, burns). If any damage is found, repair must be completed before proceeding.
- 8Install new airbag modulePosition the new airbag control module onto the mounting bracket, ensuring any spacers or insulators are correctly positioned. The module has a specific orientation and will only fit one way. Install the mounting bolts and torque to specification using a torque wrench. Do NOT overtighten as this can damage the module.Torque specModule Mounting Bolts8 Nm (6 lb-ft)
- 9Reconnect ground connectionAttach the ground wire ring terminal to the ground point. Ensure the mating surfaces are clean and making full metal-to-metal contact. Install and torque the ground bolt to specification. A proper ground connection is critical for airbag system operation.Torque specGround Bolt17 Nm (13 lb-ft)
- 10Reconnect airbag module connectorsReconnect all wire harness connectors to the new airbag module in their original positions. Push each connector straight on until you hear and feel a positive click. Verify the primary lock is engaged, then slide the secondary lock tab back into the locked position. Gently pull on each connector to verify it is fully seated.
- 11Reconnect batteryReconnect the positive battery terminal first, then the negative battery terminal. Torque battery terminal bolts to specification. Do not overtighten as this can damage the terminals.Torque specBattery Terminal Bolts6 Nm (4 lb-ft)
- 12Program and configure airbag moduleUsing Ford IDS scan tool or equivalent professional-grade diagnostic tool, access the airbag module. Perform module configuration to match the vehicle VIN, options, and seat configurations. This step is mandatory - the module will not function correctly without proper programming. Follow all on-screen prompts from the scan tool.
- 13Clear crash data and DTCsUsing the scan tool, clear all stored crash data and diagnostic trouble codes from the new airbag module. Perform a system reset. Turn ignition OFF, wait 10 seconds, then turn ignition to ON position without starting engine. Observe the airbag warning light behavior.
Reassembly
- Reinstall center console rear section, ensuring all wiring connectors are reconnected for power outlets and lighting
- Secure rear console with 8mm bolts inside storage compartment
- Reinstall center console front section, reconnecting all electrical connectors
- Secure front console with 7mm screws and replace rubber mat
- Verify all console trim pieces are properly seated and secured
Verification
- Turn ignition to ON position without starting engine - airbag warning light should illuminate for approximately 6 seconds then turn OFF
- If airbag light remains ON, flashes, or does not illuminate, DO NOT drive vehicle - system fault exists
- Using scan tool, perform airbag system self-test and verify no active or stored fault codes
- Verify scan tool shows all airbag components (driver, passenger, side, curtain, seatbelts) are communicating properly
- Check that occupant classification system (OCS) is functioning if vehicle is equipped
- Start engine and verify airbag light remains OFF during normal operation
- Test all center console functions (power outlets, USB ports, lighting) to verify proper reconnection
- CRITICAL: Have a professional technician verify proper installation if any doubts exist - airbag system must be 100% functional
