0X930AB6: Crash Message Stored

Stored crash data

What 0X930AB6 means

When the restraint system decides a crash is real, the module does two things. It fires whatever devices the situation calls for, and it writes a permanent entry saying it did. 0X930AB6 is that entry. It exists so nobody can put a car back on the road with a module that has already made its one deployment decision and pretend nothing happened.

This is why the airbag light stays on after a wreck even when every airbag, sensor, and belt has been replaced with new parts. The module is not reporting a fault with any of those parts. It is reporting its own history, and history does not get fixed by new hardware. Until that record is cleared, the module refuses to arm the system.

Common causes

• A collision severe enough for the module to command a deployment
• Airbags, curtains, or belt tensioners that fired in that collision
• A module pulled from a salvage vehicle that had already deployed
• A crash event recorded even where some devices did not fire
• A module reinstalled after a wreck without being cleared

Crash data or hardware fault?

This is stored crash data in the truest sense. It is not a measurement of a circuit and it does not come and go with the wiring. The module wrote it at the moment of the event and locked it into protected memory, and a scan tool cannot erase it. Live circuit codes are the opposite: they follow real readings and clear themselves once the readings are correct.

Does our reset clear it?

This is exactly the situation our mail-in module reset service exists for. Once the physical repairs are finished, meaning the deployed airbags, curtains, belts, and any damaged sensors have been replaced, send us the ACSM. We clear the stored crash record and return the module ready to install, and the airbag light goes out when the system finds nothing else wrong. Doing the reset before the repairs only hides a system that is still incomplete.

Which makes throw it

BMW stores 0X930AB6 in the ACSM. The hex numbering is from BMW diagnostic software, and every other manufacturer keeps the same kind of permanent crash record under its own code.

What to do next

Finish the physical repairs before you send the module, since a reset on an unrepaired car puts the light right back on and wastes the trip. Make a list of everything that deployed and replace it with genuine OEM parts, then pull the ACSM and mail it to us. Call 501-988-0611 if you want help figuring out which module your vehicle uses and where it is located. Related codes: 0X930A1C, 0X930AB7, B2722-00.
