What we do with module 77960-TR0-S811-M2
Crash data reset
We erase the crash record so the module works again after the deployed airbags and pretensioners have been replaced.
Reading and clearing fault codes
We read the SRS module codes (B-codes), check which are active and clear them after the repair.
Module identification
We read the part number, software version and VIN so we are sure we work with the right record.
How it works for Honda with this module
- You order through the form or by phone. We confirm that 77960-TR0-S811-M2 is reset over OBD, and the price.
- You bring the car to our workshop in Yambol, Bulgaria, or send the removed module by courier. Over OBD nothing is removed – we read the module through the diagnostic port.
- We check the replaced components. If there is a fault for an airbag, pretensioner or sensor, it is sorted first.
- We clear the crash data and the fault codes. Usually within an hour on site.
- Test – the airbag light goes out after the self-check; we also check the other control units for a stored crash.
If the module is already removed, we also do it on the bench – send it by courier from anywhere in the EU.
When it is needed
- After a crash with deployed airbags or pretensioners – the module keeps the record and will not re-arm the system.
- After a lighter impact where only the belt pretensioners fired – the light stays on although the airbags are intact.
- With a used module from another vehicle that has a stored crash.
- With an imported car that arrives with an airbag light and a crash record in its history.
What a reset does NOT fix
- A damaged airbag, pretensioner or crash sensor – they set a new fault immediately.
- A broken wire or corroded connector under the seat – the most common reason for the light without a crash.
- A module with a burnt board after a short circuit – for Honda we then source a module with the same part number and clone it.

Frequently asked questions
Do I have to remove module 77960-TR0-S811-M2?
Not necessarily. On Honda with this module the crash data is cleared through the diagnostic port. If you are near Yambol, Bulgaria, the job takes about an hour on site. From the rest of the EU you remove the module and send it by courier – we handle it on the bench.
Why is the airbag light still on after the reset?
Because crash data is not the only cause. If an airbag, pretensioner, crash sensor or connector is damaged or has not been replaced, the module logs a new fault. That is why we read all fault codes before the reset and tell you what still needs replacing.
Can you clear the crash data without replacing the airbags?
We do not. The module stores the record because the components have fired. We reset it only once the airbags and pretensioners have been replaced; otherwise the system will not protect the occupants in the next crash.
How much does the reset of module 77960-TR0-S811-M2 cost?
The price depends on the method (OBD or bench) and whether there are other faults. We confirm it by phone from the part number before we start. No hidden costs – if the module is faulty and cannot be recovered, you do not pay for the attempt.
What does “partial support” mean for 77960-TR0-S811-M2?
The equipment manufacturer states that for some versions of this module not all functions are available. Send a photo of the label with the full part number and version – we check in advance and tell you whether we can do it.
