Frequently asked questions

What does EPJ Airbag Solutions do?

EPJ Airbag Solutions is an online service that clears crash data from airbag control units (SRS ECUs). You read the memory of the module with your own programmer, upload the dump, and download a repaired file with the crash record removed, ready to write back to the module. The service is run by JOŽE PERPAR S.P. from Ivančna Gorica, Slovenia, and is used by workshops worldwide.

What is airbag crash data?

After a collision in which airbags or seat-belt pretensioners were deployed, the airbag control unit stores a crash record in its memory. While that record is there, the module reports a permanent fault and the airbag warning light stays on; on most modules it cannot be erased with a diagnostic tool. The module then has to be replaced or have its crash data cleared. More in What is airbag crash data.

How does the crash data reset work?

1. Create an account and buy tokens.
2. Read the memory of the airbag module (EEPROM or microcontroller data flash) and save the dump.
3. Upload the file in your account and enter the part number of the module.
4. Download the repaired file, write it back to the module and clear the fault codes.

How long does it take?

Most files are processed automatically within minutes, and every result is reviewed by us before it is released to you. If a file needs manual work, delivery can take longer and we keep you informed.

How much does an airbag crash data reset cost?

One reset costs 20 tokens. Tokens are sold in three packages: 20 tokens for 20 € (1 reset), 65 tokens for 50 € (3 resets) and 140 tokens for 100 € (7 resets), so one reset costs between 14.29 € and 20 €. There is no subscription and no VAT is added (not liable for VAT under Art. 94(1) ZDDV-1). See pricing.

How do I pay?

By card: payments are processed by Stripe and the tokens are added to your account automatically, usually within a few seconds. You can also pay by bank transfer — write to us on WhatsApp and the tokens are added once the payment arrives.

What happens if my file cannot be repaired?

You only pay for work that is delivered. If the module is not supported, the dump cannot be read or the crash data cannot be removed for any other reason, the tokens for that job go back to your account. See the refund policy.

Do tokens expire? Can I get my money back?

Tokens do not expire. They are prepaid credit and are not exchanged back into money, except that consumers in the EU can withdraw from a purchase of unused tokens within 14 days. Business customers have no right of withdrawal. Details in the refund policy.

Which airbag modules can you reset?

Our ECU database lists over 13,000 airbag control units from 96 car brands whose crash data we can clear from a memory dump: modules made by Bosch, Continental, Autoliv, TRW / ZF, Denso, Veoneer, Hyundai Mobis, Siemens / Temic and others. They use serial EEPROMs (95xxx, 93Cxx, 24Cxx) or microcontrollers such as Infineon AURIX TC2xx, Renesas RH850, Infineon XC2000 and ST SPC56. Search your part number in the ECU lookup or browse the database by brand and model.

What if my module cannot be done from a file?

Most modules are cleared from the dump automatically. For some part numbers our technician first checks whether the crash data can be cleared from the file — the ECU lookup and the upload form tell you this before you pay. Some modules can only be reset over diagnostics — for example many Toyota, Lexus, Honda and Subaru modules with a Renesas H8SX1797 or H8SX1725 — and the upload form does not accept a file for them. If a checked module turns out to be one of these, the tokens go back to your account and you can send us the module instead: we reset it on our bench (contact us first). If your part number is not listed, ask us before uploading.

Where do I find the part number of my airbag module?

It is printed on the label of the airbag control unit, for example 5Q0959655, 89170-0K010 or 0285010793. Bosch modules often carry both the car maker's number and a Bosch number starting with 0 285; you can search either one.

What do I need to read the module?

A programmer that can read the memory of the module. A serial EEPROM (95xxx, 93Cxx, 24Cxx) can be read in-circuit with a clip or with the chip removed; a microcontroller needs a tool that supports that MCU, for example over BDM, JTAG / DAP or a serial boot mode. Each module page in the ECU database shows the memory type and, where we know it, the exact dump size.

Which file formats can I upload?

BIN, ORI, EEPROM, FLASH, HEX, ZIP and RAR. Upload the file exactly as your programmer saved it and keep the original as your backup.

I don't have a programmer. Can I send you the module?

Yes. Contact us first on WhatsApp or by email with the vehicle and part number so we can confirm compatibility, then ship the module to us in Slovenia (tracked shipping recommended). We reset the crash data, verify the file and test the unit before shipping it back. Typical turnaround is 1–3 business days after we receive the unit.

Does clearing crash data repair the car?

No. Clearing crash data only resets the module. Deployed airbags, used seat-belt pretensioners, damaged sensors and wiring must be replaced, and the airbag system must be checked fault-free before the vehicle goes back on the road. The service must not be used to hide accident damage from a buyer, insurer or authority.

Who is the service for?

Workshops and professionals who are entitled to work on the vehicle. You are responsible for reading and writing the module correctly and for keeping a backup of the original file. See the terms of service.
