Vehicles: Mazda CX‑5 (2022, 2023, 2024, 2025)
Primary Part #: KEAD57K30

After a Crash, Why the Airbag Light Stays On (and How MyAirbags Helps)

When your Mazda CX‑5 experiences a crash or severe impact, its SAS Unit (airbag control module) records the event and locks. That lock preserves vital crash data for diagnostics and safety audits, but it also keeps your airbag light on even after you’ve repaired or replaced the physical components (airbags, seatbelt pretensioners, sensors). Clearing codes with a scan tool usually fails because the crash record is saved in non‑volatile memory.

MyAirbags provides a professional module reset service for this exact situation. You send us your locked KEAD57K30 module (or any listed supersession), we clear the crash/event memory, function‑test the unit on the bench, and return your same module ready to reinstall—typically plug‑and‑play once external SRS issues are addressed. If you also need airbag replacements or seatbelt pretensioner repair, those are separate services we offer as well—this page focuses specifically on the module reset (SKU 48906).

 Order SKU 48906 and ship your KEAD57K30 SAS Unit to MyAirbags for a professional reset. We’ll clear crash memory, test the module, and return it ready to reinstall.

What the SAS Unit Does (and Where It Lives)

• Monitors impact sensors, seat occupancy, seatbelt pretensioners, and airbag circuits.

• Decides when to deploy airbags/pretensioners and logs crash events.

• Stores fault codes (DTCs) and crash data in non‑volatile memory.

• Typical location: center tunnel under the console (varies by trim).

• Connectors: multi‑pin, locking tabs—avoid prying on terminals.

Safety Note: Always disconnect the 12V battery and wait the OEM‑specified interval before working on SRS components.

Symptoms & DTCs: How a Locked Module Shows Up

If crash memory is latched, you’ll commonly see the SRS lamp on and one or more of these codes:

Important: If these codes reappear immediately after clearing or on the next key cycle—and your airbags, belts, and sensors have already been addressed—the module is still locked and requires a bench reset.

Fitment & Interchange

Vehicle coverage: Mazda CX‑5 2022–2025 (all trims)
Primary part number: KEAD57K30
Mazda terminology: SAS Unit (also Airbag Control Module / SRS Control Module; RCM/SDM in other makes)

Supersessions treated as equivalent for this reset:

Confirm fitment: Read the label on your module. If it shows KEAD57K30 or any supersession above, this service applies. Do not mix with other families (e.g., D65K, KGVT)—calibrations differ.

Service Scope — What This Includes (and Doesn’t)

This reset service includes:

• Clearing crash/event memory from the SAS Unit’s non‑volatile storage

• Preserving your vehicle’s configuration (we do not alter VIN or calibrations)

• Bench testing the module’s key functions after reset

• Returning your same unit ready for reinstallation (plug‑and‑play in most cases)

This reset service does not include:

• Repairing external SRS components (airbags, pretensioners, sensors, clockspring, wiring)

• Reversing severe water/fire/impact damage to the module

• Bypassing active component or wiring faults

• Programming a used module from another vehicle

Need airbags or seatbelt pretensioner repair? MyAirbags offers those as separate services—order them alongside this reset if needed.

Step‑by‑Step: How MyAirbags Handles Your Module

1. Order SKU 48906 and print your packing slip/RMA.

2. Remove the SAS Unit (see the quick guide below). Disconnect battery; follow SRS precautions.

3. Package the module: antistatic bag, foam/bubble on all sides, no loose hardware.

4. Ship to MyAirbags. Include contact details and return address in the box.

5. Reset & Test: We clear crash memory and bench‑test key functions.

6. Return & Reinstall: Reinstall the module, clear any remaining non‑crash DTCs, and verify the SRS lamp cycles off.

Pre‑Shipment Checklist

• ✅ Label shows KEAD57K30 or a listed supersession

• ✅ No cracked housing, burnt board, or heavy corrosion

• ✅ Airbags/pretensioners/sensors addressed or planned

• ✅ RMA/packing slip and return address inside the box

Packaging Tips (to prevent transit damage)

• Use a sturdy box; pad all six sides; immobilize the unit.

• Place the module in an antistatic bag; avoid foam shedding into connectors.

• Do not include bolts/screws loose in the box; they can damage the PCB.

• Label the outside of the box with SKU 48906

Quick Removal Guide (CX‑5 2022–2025)

• Disconnect the 12V battery (negative terminal first) and wait per Mazda service manual.

• The SAS Unit is typically on the center tunnel under the console.

• Remove trim carefully; use plastic tools to protect clips.

• Photograph connectors; press lock tabs—do not pry.

• Keep the label intact for part verification.

• Store the unit flat; avoid moisture and magnets.

Always follow Mazda service procedures and torque specs during reinstallation.

Installation & Post‑Reset Verification

1. Reconnect the battery; turn ignition OFF → ON without cranking.

2. Ensure the SRS lamp illuminates, then turns off after the bulb check.

3. Scan for DTCs. If any component codes remain (e.g., open/short on airbags or pretensioners), resolve those separately.

4. Follow any Mazda‑specified calibrations required after collision repair (e.g., occupant classification/seat weight zero‑point where applicable).

5. Perform a road check; re‑scan and confirm no returning SRS faults.

Troubleshooting After Reset

• Airbag or pretensioner circuit codes remain: Inspect connectors, clock‑spring, squib wiring, and ground points.

• Occupant/seat sensor codes: Check seat sensor harness; perform calibration per the Mazda service manual.

• Battery/voltage codes: Verify battery health and system grounds—low voltage can trigger SRS faults.

• New DTC appears only while driving: Inspect impact sensors and harness routing for intermittent opens.

FAQs

Does MyAirbags handle airbags and seatbelts too?
Yes. We offer airbag solutions and seatbelt pretensioner repair as separate services. This page focuses on the SAS Unit reset.

Will a scan tool clear these crash codes?
Not permanently. Crash data is stored in non‑volatile memory; codes often return on the next key cycle without a bench reset.

Do I need to reprogram the module after your reset?
Usually no—because it’s your original unit matched to the vehicle, it’s typically plug‑and‑play once external faults are addressed.

Can you reset a water‑ or fire‑damaged module?
Severe damage may be non‑repairable. Send photos before shipping so we can advise.

What if the airbag light is still on after reinstall?
Scan and resolve any remaining component DTCs (airbags, belts, sensors, clockspring). Those are outside the module reset scope.

Do you change my VIN or coding?
No. We clear crash/event memory only—we do not modify VIN or calibrations.

Can I send a used module from another car instead?
We recommend resetting your original module. Used units may carry incompatible configuration or their own crash data.

Is this service the same as “refurbished”?
No. This is your original module, reset and tested.

How long does the process take?
Turnaround is fast and shop‑friendly. Actual times vary based on shipping and workload.

Will this fix collision‑avoidance warnings too?
If those warnings stem solely from crash memory in the SAS Unit, the reset typically clears them. Active sensor/calibration issues must be handled separately.

Legal & Safety Notice

Working on SRS systems involves safety risk. Only trained personnel should remove/reinstall modules. Always follow Mazda OEM procedures. Do not operate the vehicle with the SRS lamp illuminated.
