What steps should I follow to correctly install a new or reset (ACM) airbag control module?

Installing a new or reset Airbag Control Module (ACM) is a task that should be approached with caution given the critical safety functions of the module.
 

Here's a step-by-step guide to help you install (ACM) Airbag Control Module correctly

 

Safety First

  • Disconnect the vehicle's battery. It's usually best to disconnect the negative terminal first, then the positive. This will ensure there's no power going to the airbag system, reducing the risk of accidental deployment.
  • Wait for at least 10 minutes after disconnecting the battery before starting work on the SRS system. This allows any residual energy in the system to dissipate.

Preparation

  • Make sure the replacement ACM is the correct part for your vehicle, considering the make, model, trim level, and year.
  • Ensure you have all necessary tools at hand and that the work area is clean and free from potential hazards.

Removal of the Old Airbag Computer Module (ACM)

  • Locate the old ACM. As previously mentioned, it's often found under the center console or dashboard, but the exact location can vary.
  • Carefully disconnect any electrical connectors attached to the ACM. These connectors are usually color-coded or uniquely shaped to ensure correct reconnection, but it's always a good idea to take photos or make notes before disconnecting them.
  • Remove any mounting screws or bolts holding the ACM in place and then remove the ACM from its mounting location.

Installing the New or Reset Airbag Control Module (ACM)

  • Position the new or reset ACM in the location where the old one was removed.
  • Securely fasten it using the mounting screws or bolts. Ensure it's tightly secured but be careful not to overtighten and damage the module or its mounting points.
  • Reconnect the electrical connectors. Ensure they are securely connected and locked in place.

Reconnect the Battery

  • Reconnect the positive terminal first, then the negative.

Initial Testing

  • Turn on the ignition without starting the engine and observe the airbag warning light. It should illuminate for a few seconds and then turn off, indicating that the system is functioning correctly.
  • If the airbag light remains on or flashes, there might be an issue. You'll need to diagnose the problem, possibly with the help of a diagnostic tool.

Calibration and Programming

  • If you sent your original airbag control module to MyAibags to have it reset, then no additional programming will be needed and will be plug-n-play when you get it back!
  • Depending on the vehicle, the new or reset ACM may require calibration or programming, as previously discussed. Use a diagnostic tool to calibrate the ACM for the specific make, model, and trim level of the vehicle.
  • Ensure that the ACM is correctly programmed with the vehicle's VIN if required. 

Check for Diagnostic Trouble Codes (DTCs)

  • Use an OBD-II scanner to read any diagnostic trouble codes stored in the vehicle’s computer. Clear any codes if necessary and check if they return

Perform a System Check

  • If possible, perform a system diagnostic check using specialized diagnostic software or consult a professional to ensure all components of the airbag system are communicating correctly and functioning as expected.

Verify Proper Installation

  • Once you confirm the system is error-free and functioning correctly, ensure all components are secure and the work area is clean.

Seek Professional Assistance If Unsure

  • If at any point you're unsure about the installation process or encounter problems, consult a professional mechanic or technician. Given the critical safety functions of the ACM, it's always better to be safe and seek expert assistance if needed. You can always give MyAirbags a call at 888-779-9029 and we can help you!
