Does this reset remove all Mazda crash data?

Yes—deployment logs, crash counters, and locked RCM faults are cleared.

Will I need dealer programming afterward?

No. Your original RCM remains plug-and-play.

What if the airbag light stays on?

Then a live hardware fault exists (sensor, wiring, pretensioner, or airbag).

Do you support older and newer Mazda platforms?

Yes—Ford-based, SkyActiv, and current Mazda models are all supported.

Does resetting affect my vehicle’s VIN or coding?

No. All original coding remains intact.

Mazda Airbag Module Reset Service (RCM Crash Data Removal)

Mazda’s Restraint Control Module (RCM) is designed to permanently lock after any collision event. When a crash, near-impact, or seatbelt tensioner activation occurs, the module records crash data that cannot be cleared with standard diagnostic tools. This prevents the supplemental restraint system (SRS) from re-arming and keeps the airbag light illuminated. Our Mazda Airbag Module Reset Service clears these non-removable crash events at the memory level, restoring your original RCM so it becomes fully functional again with no dealer programming required.

Why Mazda RCM Modules Store Permanent Crash Data

Mazda uses Bosch, Hitachi, and Denso-based RCM units depending on model year and platform. Regardless of manufacturer, these modules write deployment information to a protected section of EEPROM or MCU flash memory whenever the system detects:

  • Front or side impact detection
  • Seatbelt pretensioner activation
  • Airbag stage deployment (driver, passenger, or side curtain)
  • Crash sensor impact thresholds exceeded
  • Rollover event or rollover stability intervention

These events create non-clearable Diagnostic Trouble Codes (DTCs) such as:

  • “Crash Event Storage Full”
  • “RCM Fault After Deployment”
  • “Controlled Deployment Recorded”
  • “Module Is Locked – Replace RCM”

Generic OBD scanners and even Mazda IDS/MDARS tools cannot remove these records once stored. A bench-level memory repair is required.

What Our Mazda RCM Reset Service Fixes

  • Permanent crash data stored
  • Airbag light illuminated after an accident
  • Seatbelt deployment history stored
  • Driver/passenger/side airbag deployment recorded
  • Hard faults that reappear instantly after clearing
  • Internal RCM “locked” state

This restores full SRS functionality and allows the system to perform normal safety checks again after installation.

Supported Mazda Models

Our service covers nearly every Mazda equipped with an RCM including older Ford-platform Mazdas and modern SkyActiv models:

  • Mazda 2
  • Mazda 3 (all generations including BK, BL, BM, BP)
  • Mazda 5
  • Mazda 6 (GG, GH, GJ, GL)
  • Mazda CX-3
  • Mazda CX-30
  • Mazda CX-5 (all generations)
  • Mazda CX-7
  • Mazda CX-9
  • Mazda RX-8
  • Mazda MX-5 / Miata (NB, NC, ND)
  • Mazda Tribute (Ford-based RCM)
  • Mazda B-Series trucks

Common Mazda RCM / SRS Module Part Numbers

Typical Mazda restraint module part number formats include:

  • BBM4-57K30 / BBM4-57K31
  • GJ6A-57K30
  • KD45-57K30
  • B45A-57K30
  • C236-57K30
  • EG21-57K30
  • F1YB-57K30
  • Denso / Bosch 0 285 xxx xxx variations
  • FoMoCo RCM units in Mazda-Ford joint platforms

If your module contains Mazda, Denso, Bosch, Temic, Hitachi, or FoMoCo markings, we support it.

Technical Overview of the Mazda RCM Reset Process

Mazda RCMs store crash data in a combination of EEPROM (often 95160, 95320, or 95640 series) and internal microcontroller flash memory. Our process includes:

  • Bench reading the EEPROM and MCU flash
  • Extracting deployment logs, sensor timestamps, and event flags
  • Clearing crash records and correcting checksums
  • Restoring RCM operational logic and integrity validation data
  • Performing post-reset self-check simulation

This is a true memory-level correction consistent with Mazda’s RCM design—not a simple code erase.

Mazda Platform Differences We Support

Older Mazda/Ford Shared RCM Units

  • Common in Mazda Tribute, early Mazda 6, Mazda 3, and B-Series trucks
  • Often contain Motorola/Freescale microcontrollers
  • Store crash data in mirrored memory blocks

SkyActiv Generation Mazdas (2013–Present)

  • Advanced Denso or Bosch RCM units
  • More complex data structures
  • Multiple impact snapshots stored

Late-Model Mazda i-ACTIVSENSE Equipped Vehicles

  • RCM may interface with radar, camera, and safety subsystems
  • Crash event logs can disable multiple systems including SCBS and SBS

All of these are resettable and will return to normal function once installed and verified by the vehicle.

What This Service Does Not Fix

  • Flood-damaged RCM units
  • Physically damaged circuit boards
  • Live faults caused by bad airbags, pretensioners, or sensors
  • Open circuits, wiring issues, or sensor communication faults

Once the reset module is installed, the SRS lamp will only turn off if no active hardware issues remain.

Why Resetting the Original Mazda RCM Is the Best Option

Mazda RCMs are coded to the exact configuration of the vehicle including:

  • Airbag stages and positions
  • Seatbelt and pretensioner type
  • Passenger occupancy sensor calibration
  • VIN and variant coding
  • Chassis and sensor configuration

Replacing the module may require dealer-level calibration, VIN writing, and occupant sensor learning. Resetting the original avoids all of this.

After Reinstalling the Reset RCM

Once reinstalled, the Mazda’s SRS performs its startup integrity check. If every component passes, the airbag light will shut off automatically with no additional programming or coding required.
