Why the Airbag Light Stays On After Repairs (and How MyAirbags Fixes It)
Your Mazda CX‑5’s SRS is designed to keep you safe. When the vehicle detects a crash or severe impact, the SAS Unit(airbag control module) records the event and locks itself. This preserves critical crash data but also leaves the airbag light on even after physical components—airbags, seatbelt pretensioners, and sensors—have been replaced or repaired. Clearing codes with a standard scan tool rarely works because the crash record is stored in non‑volatile memory.
MyAirbags solves this last mile of the repair by resetting your original D65K57K30A SAS Unit (or any listed supersession). You ship it to us under SKU 48906, we clear crash/event memory, bench‑test key functions, and return your same module ready to reinstall—usually plug‑and‑play once any external SRS issues are addressed.
Order SKU 48906 send your D65K57K30A SAS Unit to MyAirbagsfor a professional crash‑data reset and bench test — most jobs completed in 24 hours*.
What the SAS Unit Does (and Where It’s Located)
-
Monitors impact sensors, seat occupancy sensors, airbags, and pretensioners.
-
Commands deployment when thresholds are met; logs crash events for diagnostics.
-
Stores DTCs and crash data in non‑volatile memory, which can prevent resets via normal scan tools.
-
Typical location: center tunnel under the console (location may vary slightly by trim).
-
Connectors: Multi‑pin with locking tabs—do not pry on terminals.
Safety Note: Always disconnect the 12V battery and wait the Mazda‑specified interval before working on any SRS component.

Symptoms & DTCs of a Locked D65K57K30A Module
If crash memory is latched, you’ll commonly see the SRS lamp on and one or more of the following DTCs:
| Code | Meaning | Typical Context |
|---|---|---|
| B1A55:00-08 | Crash record output | Appears post‑collision or after failed clear attempts; indicates stored crash record |
| B1206:00-08 | Crash event storage full and locked | Returns immediately after clearing; storage latched |
| B1206:00-09 | Crash event storage full and locked | Variant of the above; same fix required |
| B1193:00-8B | Crash event storage full and locked | Often paired with front‑end or multi‑event logs |
| U2107:00-48 | Collision mitigation by braking | Frequently appears alongside crash record; clears after module reset if no active sensor faults |
Signal to act: If these codes come back immediately after clearing or on the next key cycle—and airbags, belts, and sensors are already 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: D65K57K30A
Mazda terminology: SAS Unit (also called Airbag Control Module / SRS Control Module; equivalent to RCM/SDM in other brands)
Supersessions treated as equivalent for this reset:
| Primary | Recognized Supersessions |
| D65K57K30A | D65K‑57‑K30A, D65K‑57‑K30B, D65K‑57‑K30C |
Confirm fitment: Read the white label on the module. If it shows D65K57K30A or any supersession above, this service applies. Do not mix with other CX‑5 families (e.g., KEAD, KGVT)—calibrations differ.

Installation & Post‑Reset Verification
-
Reconnect battery; cycle ignition OFF → ON without cranking.
-
Confirm the SRS lamp illuminates and turns off after the bulb check.
-
Scan for codes. If any component DTCs remain (e.g., airbag or pretensioner circuit), address those separately.
-
Complete any Mazda‑specified calibrations after collision repair (e.g., occupant classification zero‑point where applicable).
-
Road‑test, re‑scan, and confirm no SRS faults return.
Troubleshooting After Reset
-
Airbag or pretensioner circuit DTCs persist: Inspect connectors, clockspring, squib wiring, grounds.
-
Occupant/seat sensor faults: Check harness; perform calibration per Mazda manual.
-
Voltage‑related codes: Verify battery/charging system and main grounds.
-
Intermittent during drive: Inspect impact sensors and harness routing for chafing or loose pins.

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.
