Q: Do I need to code the ACSM after reinstalling it?

A: No. Once reset, your module keeps your coding and VIN. It is plug-and-play if no other SRS faults are present.

Q: Will this service fix my airbag light?

A: Yes—if the only issue is stored crash data. Any active component or wiring faults must be repaired first.

Q: Can you reset ACSM modules from all MINI models?

A: Yes, we support all R-series and F-series MINI vehicles that use ACSM or MRS units.

Q: What if my module has water damage?

A: Flood-damaged or burnt modules cannot be reset. In that case, replacement is required.

Q: How long does the reset take?

A: Typical turnaround is 1–2 business days once your module arrives.

Mini Cooper Airbag Module Reset Service (ACSM / MRS Crash Data Removal) The Mini Cooper uses BMW’s Advanced Crash Safety Module (ACSM), also referred to as the Multiple Restraint System (MRS). After any collision, impact, or seatbelt pretensioner activation, the ACSM stores permanent crash data that cannot be cleared with a diagnostic scan tool. This crash data forces the airbag light to remain on, even after all damaged components have been replaced. Our professional Mini Airbag Module Reset Service removes these locked crash events at the memory level so your original ACSM module becomes safe and fully reusable—no dealer programming required. Why the Mini ACSM Locks After an Accident Mini Cooper models share BMW’s safety electronic architecture. When the ACSM detects a deployment event, it writes multiple crash records to EEPROM or internal MCU memory. These include: Crash Event Storage Primary/Secondary Impact Counters Belt Tensioner Deployment Records Airbag Stage 1 / Stage 2 Deployment Flags Internal “Control Unit Fault After Crash” Once stored, these records prevent the ACSM from rearming the SRS system until they are professionally removed. Standard OBD scanners, dealer ISTA/D, Autel, Launch, or Foxwell tools cannot erase these permanent memory blocks. What Our Mini ACSM Reset Service Fixes Crash Data Stored / Crash Event Stored ACSM Internal Fault Following Crash Seatbelt Pretensioner Deployment Stored Driver Airbag / Passenger Airbag Deployment Recorded Hard Codes That Cannot Be Cleared Airbag Light On After Accident Repair “ACSM Coding Blocked” due to crash memory This service restores your module to factory-clear condition while retaining your vehicle-specific coding and VIN. Supported Mini Models (2002–Present) Our reset service covers all Mini platforms equipped with ACSM/MRS units, including: Mini Cooper R50 / R53 Mini Cooper S R52 / R53 Mini Cooper R55 Clubman Mini Cooper R56 / R57 (most common crash data issues) Mini R58 Coupe / R59 Roadster Mini R60 Countryman Mini R61 Paceman Mini F54 Clubman Mini F55 / F56 / F57 Hatch & Convertible Mini F60 Countryman If your Mini has an ACSM, MRSZ4, MRSZ5, or newer Bosch-based ACSM unit, we can reset it. Common Mini / BMW ACSM Part Numbers We Support These part numbers are extremely common across Mini platforms: 6577-xxxxxxx (all BMW/Mini ACSM series) 3452-xxxxxxx 7212-xxxxxxx 9851-xxxxxxx Bosch 0 285 xxx xxx Temic/Continental ACSM units BMW/Mini ACSM modules often have multiple suffix variations. Any variation of the above families is supported. Technical Breakdown of the Reset Process Mini ACSM units store crash data in both EEPROM and MCU internal flash. Our reset procedure involves: Direct bench connection to the ACSM microcontroller Reading EEPROM and MCU flash data using automotive-grade programming tools Extracting event logs, deployment counters, impact snapshots, and live crash data Clearing deployment records at the memory structure level Correcting checksums and restoring the ACSM’s integrity tables Simulating post-reset initialization to confirm the ACSM boots with no internal crash faults This is not a code-clear or “quick erase”—it is a full memory rebuild consistent with BMW/Mini ACSM architecture. ACSM Generations Supported ACSM / ACSM II (R-Series Mini) R50, R52, R53 R55, R56, R57 R58, R59, R60, R61 ACSM III / ACSM IV (F-Series Mini) F54 Clubman F55/F56 Hatch F57 Convertible F60 Countryman Each uses different memory maps and crash structures—but all can be safely reset. What This Service Fixes vs. What It Does Not Fix This service fixes: Stored crash data in ACSM/MRS Non-clearable deployment codes Internal control unit faults caused by crash memory Hard faults that return immediately after clearing This service does NOT fix: Flood-damaged ACSM modules Physically burnt or cracked boards Faulty airbags or pretensioners that are still bad Wiring faults, sensor communication issues, or open circuits After reinstalling the module, the airbag light will turn off automatically once the system passes a full SRS self-test with no live faults present. Why Resetting the Original Mini ACSM Is Better Than Replacement Mini ACSM modules are coded to the vehicle’s configuration, crash zones, seat occupancy sensor type (OC3/OCS), airbag variants, and VIN. Replacing an ACSM often requires: VIN coding FA/VO coding with ISTA/P Airbag parameter programming Seat occupancy recalibration Resetting your original ACSM avoids all of this and ensures exact compatibility with your vehicle’s SRS configuration. After Reinstalling the Reset ACSM Once the ACSM is installed back in the Mini, the SRS system will automatically perform its internal power-on checks. If no wiring or component faults remain, the airbag light will go out by itself. No coding, no initialization, and no dealer visit are required.
