BMW Airbag / ACSM / SRS Module Services
After a deployment, the BMW ACSM (Advanced Crash Safety Module, also called the airbag / SRS module) locks crash data into the EEPROM. Replacing the ACSM with a new one is one path; the other is to bench-reset / clone the existing ACSM. We perform BMW ACSM crash reset, ACSM4 clone, and full SRS bench services for many BMW model years. This service is intended for qualified SRS technicians and professional installers.

Not Sure Which Service to Choose?
If you are unsure which option matches your BMW module, the safest path is to email or text us photos before ordering: full label of the original module (the one you want serviced), full label of the donor module if you already have one, the part number, hardware revision, and software/calibration sticker, and a photo of the connector pinout if visible. We will confirm whether the service is supported for your specific part number and hardware revision before you order and ship.
Compatibility Warning
Airbag reset requires the SRS components on the vehicle to already be replaced before the module is re-installed. ACSM4 (F-series era) cloning requires a donor ACSM of the same hardware revision. Confirm the deployed parts have been replaced before ordering.
What to Ship
- Your original BMW module (the failed/locked unit), clearly marked “ORIGINAL”
- If applicable: a donor module, clearly marked “DONOR” — same part number family and hardware revision as the original
- Your order receipt printed, or order number written on a slip in the box
- Your return shipping address
- Ship to the address shown on your order receipt at checkout (we operate from 2 locations and route based on tool availability and turnaround)

FAQ
What is ACSM4? ACSM4 is the Advanced Crash Safety Module generation 4 used on F-series and early G-series BMWs. ACSM4 is paired to the car and requires either a clone from your original or a virginized donor.
What does the airbag reset include? Bench EEPROM read, reset of crash flags back to pre-crash state, and the module returned ready for re-installation into a vehicle with new SRS components.
Will the airbag light go away? If the deployed SRS components have been replaced and no other faults exist, the airbag light should clear after the reset and a successful self-test on reinstall.
