Airbag control unit with part number 77960-T2F-A010-M4

What does the airbag control unit 77960-T2F-A010-M4 do?

The airbag control unit 77960-T2F-A010-M4 controls the SRS restraint system for Honda. It processes the measurements of the crash sensors, decides within milliseconds in the event of an impact whether airbags and seatbelt pretensioners fire, and monitors all components continuously. It shows faults via the airbag warning light.

After an accident the unit records crash data and locks itself. The control unit thus combines two tasks: triggering at the moment of impact and recording the event.

For this reason you should keep this property in mind before removing or reading out the unit.

Why does the control unit 77960-T2F-A010-M4 fail?

The most common cause on the 77960-T2F-A010-M4 is crash data stored after an accident, even without a triggered airbag. In addition there are ageing components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

An ordinary diagnostic tool cannot erase crash data. Airbag24 removes it in a targeted way during the repair.

Voltage spikes arise, for example, from a weak battery or when a jump-start cable is connected, and they can put a strain on components.

How can you tell that the 77960-T2F-A010-M4 is defective?

The airbag warning light in the instrument cluster indicates the defect on the 77960-T2F-A010-M4 when it lights up permanently or intermittently. Also possible are an error message in the instrument cluster, a missing connection of the diagnostic tool, or a fault memory that cannot be cleared.

The warning light is the most important warning sign. As long as the fault exists, airbags and seatbelt pretensioners may not deploy in an emergency.

Take a fault memory that cannot be emptied just as seriously.
