Why the Airbag Light Stays On After Repairs (and How MyAirbags Fixes It)

The Mazda CX‑60’s Supplemental Restraint System is designed to protect occupants during a collision—and to preserve key diagnostic data afterward. When a crash or severe impact is detected, the SAS Unit (airbag control module) records the event and locks. That lock keeps a permanent crash record in non‑volatile memory, which is why the airbag light stays on even after physical components like airbags, seatbelt pretensioners, and sensors have been replaced. Clearing codes with a scan tool usually won’t remove a latched crash record.

MyAirbags resolves this final step by resetting your original CX‑60 SAS Unit (KR9P‑57K30 or K31V‑57K30). You ship the module under SKU 48906, we clear crash/event memory, bench‑test the unit, and return your same module ready to reinstall—typically plug‑and‑play once external SRS faults are addressed. If you also need airbag replacements or seatbelt pretensioner repair, those are separate MyAirbags services—this page focuses on the module reset.

 Send your KR9P‑57K30 / K31V‑57K30 SAS Unit to MyAirbags for a professional crash‑data reset and bench test.

What the SAS Unit Does (and Where It’s Located)

• Monitors impact sensors, occupancy/weight sensors, airbags, and pretensioners.

• Commands deployment when thresholds are met; logs crash events for diagnostics.

• Stores DTCs and crash data in non‑volatile memory; ordinary clears won’t remove a locked crash record.

• Typical location (CX‑60): center tunnel under the console (may vary slightly by trim).

• Connectors: Multi‑pin with locking tabs—do not pry on terminals.

Safety Note: Disconnect the 12V battery and wait the Mazda‑specified interval before working on any SRS component.

Symptoms & DTCs of a Locked CX‑60 Module

If crash memory is latched, you’ll typically see the SRS lamp on and one or more of these Diagnostic Trouble Codes:

Signal to act: If these codes reappear immediately after clearing or on the next key cycle—and airbags, belts, and sensors are already addressed—the module is still locked and needs a bench reset

Fitment & Interchange

Vehicle coverage: Mazda CX‑60 2024–2025 (all trims)
Primary part numbers: KR9P‑57K30, K31V‑57K30
Mazda terminology: SAS Unit (also called Airbag Control Module / SRS Control Module; equivalent to RCM/SDM in other brands)

Confirm fitment: Read the white label. If it shows KR9P‑57K30 or K31V‑57K30, this service applies.

How MyAirbags Handles Your Module

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

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

3. Package the module: antistatic bag + foam; pad all six sides; no loose hardware.

4. Ship to MyAirbags with your contact info and return address in the box.

5. Reset & Test: We clear crash memory and bench‑test the unit.

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

Pre‑Shipment Checklist

• Label shows KR9P‑57K30 or K31V‑57K30

•  No cracked housing, burnt board, or heavy corrosion

•  Airbags/pretensioners/sensors repaired or planned

• RMA/packing slip and return address inside the box

Packaging Tips (Prevent Transit Damage)

• Use a sturdy box; immobilize the unit with foam/bubble on all sides.

• Place the module in an antistatic bag; avoid materials that shed into connectors.

• Do not ship bolts/screws loose in the box.

• Mark the outside of the box with SKU 48906 for receiving.

Quick Removal Guide (CX‑60 2024–2025)

• Disconnect the 12V battery (negative 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 and finishes.

• Photograph connectors; depress locking tabs—no prying on pins.

• Keep the label intact for part verification.

• Store flat; keep dry; avoid magnetic fields.

Always follow Mazda service procedures and torque specs during reinstallation.

Installation & Post‑Reset Verification

1. Reconnect battery; cycle ignition OFF → ON without cranking.

2. Confirm the SRS lamp illuminates and turns off after the bulb check.

3. Scan for codes. If any component DTCs remain (e.g., airbag or pretensioner circuit), resolve those separately.

4. Complete any Mazda‑specified calibrations after collision repair (e.g., occupant classification zero‑point where applicable).

5. Road‑test, re‑scan, and confirm no SRS faults return.

Case Study #1 — 2024 Mazda CX‑60 (Homura)

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 car, 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 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 depend 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. Sensor/calibration issues must be handled separately.

Finish the Repair the Right Way with MyAirbags

The CX‑60’s SRS is engineered to lock the control module after a deployment. That design preserves crash data—but it also means the airbag light stays on until the event memory is professionally cleared. With MyAirbags, you keep your original KR9P‑57K30 / K31V‑57K30 module, avoid unnecessary replacement costs, and restore proper SRS readiness once external faults are addressed. If the dash warning persists or codes like B1A55 and B1206 keep returning, completing this final step is what gets the system back to normal.

Order SKU 48906 and send your CX‑60 SAS Unit to MyAirbags today. We’ll clear crash data, test the module, and return it ready to reinstall—so your Mazda’s safety system works the way it was designed to.
