Airbag Module Reset (ACM) for Mazda (Bosch)

Mazda vehicles manufactured from 2022 to 2025 are equipped with Bosch airbag control modules, also known as ACM or SAS units. These modules are integral to the vehicle's Supplemental Restraint System (SRS), designed to deploy airbags and tighten seatbelts during a crash. After even a minor accident, these units will store crash data and become locked. Once this happens, the airbag light remains on, and your safety system may be compromised. Many Mazda owners are surprised when dealerships insist the only fix is to replace the entire module. This replacement can cost between $400 and $600, plus labor and programming. However, there’s a smarter and far more affordable alternative. At MyAirbags, we provide certified ACM reset services that restore the original module to factory condition. Instead of replacing it, you send it to us, and we clear the crash data, test the unit, and send it back—ready to reinstall. Contact us for trusted seatbelt repair and airbag reset solutions that save both time and money.

What Is a Locked Airbag Module (ACM/SAS Unit)?

The airbag module in your Mazda, often referred to as the SAS unit (Supplemental Restraint System), controls all airbag and seatbelt pretensioner deployments. In modern Mazdas, this module is manufactured by Bosch and designed to lock after a collision, storing essential crash codes.

These crash codes are critical for diagnostic purposes but cannot be cleared with a standard OBD-II scanner. Some of the common codes stored in these modules include:

• B1A55:00-08 – Crash Record Output
• B1206:00-08 / 00-09 – Crash Event Storage Full and Locked
• B1193:00-8B – Storage Full
• U2107:00-48 – Collision Mitigation Fault

Once these codes are triggered, the airbag light will stay on, and your safety system is disabled until the issue is resolved. This leaves you and your passengers at risk in a future collision. Our "crash codes and airbag module replacement guide" explains these codes in depth and outlines your best course of action. Instead of opting for an expensive replacement, consider resetting the original module—an option that dealerships won’t often recommend.

When You Need an Airbag Module Reset for Your Mazda?

After a collision, even if airbags don’t deploy, Mazda vehicles often store crash data in the airbag control module (ACM). This results in a persistent airbag light and a disabled safety system. Many owners don’t realize that a full module replacement isn’t necessary. Our team at MyAirbags provides certified resets that resolve these issues quickly and affordably. The sections below explain exactly when and why your Mazda may need this service.

Recognizing the Warning Signs

Mazda owners often encounter issues after an accident, even when the collision seems minor. One of the first signs is the persistent airbag warning light on the dashboard. This indicates that the ACM has logged crash data and is now locked. Even if the airbags didn’t deploy, the system can still be compromised. Traditional scan tools won’t clear these deep crash codes. Drivers are left unsure if their safety system will function in a future crash. This is when a reset becomes not only necessary but urgent. At MyAirbags, we guide you through this process from start to finish.

Post-Collision Repairs Aren’t Enough

Many customers believe that once visible damage is fixed, the car is fully restored. However, this isn’t true for the airbag system. Body shops can’t clear the stored crash records in your ACM. As a result, the airbag light remains on after repairs are complete. A technician may misdiagnose the issue and suggest replacing the module. This is where we come in to save you time and money. Our reset service restores the original module without needing additional reprogramming. Your safety system becomes fully functional again.

When Dealerships Recommend Replacement?

It’s common for Mazda dealers to tell customers a new airbag module is the only option. This typically involves a price tag of several hundred dollars. They do this because they lack the tools to clear Bosch ACM crash codes. But that doesn’t mean your module is broken or unusable. At MyAirbags, we specialize in restoring these modules to factory settings. There’s no need for VIN pairing or programming after reinstall. We help you retain your OEM equipment while avoiding dealership costs. Most importantly, your system is back online quickly and safely.

Why You Should Choose a Reset?

Resetting your airbag module is an efficient, reliable solution that saves money. It ensures your safety system is active without the delays or costs of full replacement. We preserve your vehicle’s original configuration and eliminate the need for additional coding. Our certified technicians verify functionality before returning the unit. You’ll receive a ready-to-install module that clears your airbag warning light immediately. There’s no guessing—just a tested, working system. Choosing MyAirbags means choosing transparency and proven results. Let us help you stay safe on the road without overspending.

Case Study: Mazda CX-5 2023 – Reset vs Replace

Let’s look at a real-world example that shows why our reset service is the smart choice. A customer with a 2023 Mazda CX-5 came to us after a minor collision triggered crash codes B1A55 and B1206. The dealership told the customer the only fix was to replace the ACM unit.

The quote? $560 for the part alone—excluding labor and coding fees. In contrast, the customer sent the module to us. We performed a same-day reset, tested the unit, and returned it fully functional. The crash data was cleared, the airbag light was off, and the car passed inspection with no errors.

In total, the customer saved over $400 compared to the dealership. Their comment? “Mazda dealer told me it wasn’t repairable—MyAirbags proved them wrong.” We see this scenario often, and every time we save a customer from unnecessary expenses, we reinforce our commitment to affordable safety solutions.

Why Mazda Dealers Recommend Replacements (and Why You Shouldn’t)?

Dealerships are bound by manufacturer guidelines and cannot clear hard crash codes from Bosch airbag modules. Their default solution is full replacement, which often costs hundreds of dollars and requires additional programming.

What they don’t mention is that these modules are resettable with the right equipment and expertise. At MyAirbags, we restore your original ACM to like-new condition. Our method avoids the re-coding process altogether and ensures compatibility with your vehicle.

We understand the dealership’s limitations, but that doesn’t mean you should absorb the cost. Our service follows every step in the "Steps to Install a New or Reset (ACM) Airbag Control Module" guide. The result? A working airbag system, no programming required, and a significantly lower repair bill.

How the MyAirbags Reset Process Works?

Understanding our reset process helps Mazda owners feel more confident and informed. We break the reset journey into four essential steps, each ensuring a smooth experience. Every phase is handled by professionals to guarantee safety and reliability. Here's how we restore your airbag system.

Step 1: Remove the Module Safely

Start by disconnecting the battery to prevent electrical issues. Locate the module under the center console or front seats. Carefully unbolt and remove the module without damaging connectors. Secure it in anti-static packaging before shipping. Make sure to label the package clearly for tracking. This step ensures your module arrives safely at our facility.

Step 2: Ship the Module to Us

Use any carrier with tracking to send your module to MyAirbags. We recommend next-day or two-day delivery for speed. Include your order form and return address. Our intake team logs each arrival and confirms condition. Communication is sent to notify you that diagnostics are beginning. Fast delivery ensures minimal downtime for your vehicle.

Step 3: Diagnostic and Factory Reset

Our IPC-certified technicians inspect the module thoroughly. We scan for crash codes and corruption. The module then goes through a crash data clearing procedure. We restore all settings to factory defaults. A final diagnostic ensures no residual codes remain. Every module is tested to meet OEM specifications.

Step 4: Reinstall and Restore Functionality

Once received, your module is ready for reinstallation. No dealer programming or VIN matching is needed. Reconnect your battery after installing the module. Start your vehicle to confirm the airbag light is off. Conduct a basic diagnostic scan for peace of mind. Your SRS system is now fully restored and operational.
