Airbag control unit with part number 77960-TV0-Q910-M4

What does the airbag control unit 77960-TV0-Q910-M4 do?

The 77960-TV0-Q910-M4 is the central control unit of the SRS restraint system in Honda vehicles. In an accident it processes the signals from the crash sensors and triggers the appropriate airbags and seatbelt pretensioners within milliseconds.

In everyday use it checks the system continuously. It indicates any faults it finds via the airbag warning light, so that the driver is informed.

If an accident is registered, the unit stores crash data and then locks itself.

Why does the control unit 77960-TV0-Q910-M4 fail?

The 77960-TV0-Q910-M4 most often fails because of stored crash data left behind after an accident, even if no airbag has deployed. Other causes are aged components, cold solder joints, corrosion on plugs and voltage spikes, for example from a weak battery.

Crash data cannot be erased with an ordinary diagnostic tool. It therefore stays in the unit, with nothing visible on the car.

Electronics age, solder joints can go cold, and moisture or corrosion damage the plug connections.

How can you tell that the 77960-TV0-Q910-M4 is defective?

If the airbag warning light in the instrument cluster lights up on the 77960-TV0-Q910-M4, either permanently or intermittently, the unit is indicating a defect. A fault message appears alongside it, and the diagnostic tool either cannot find the control unit or the fault memory cannot be erased.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy. Clarify the warning promptly.
