Airbag control unit with part number 77960-TEA-M910-M4

What does the airbag control unit 77960-TEA-M910-M4 do?

For Honda, the airbag control unit 77960-TEA-M910-M4 is the central control unit of the SRS. It captures the crash sensors, decides in an accident within fractions of a second about airbags and seatbelt pretensioners, and keeps the system under constant watch.

If it detects a fault, it reports this via the airbag warning light in the instrument cluster. After an accident it records crash data and locks itself.

This control unit is part of the safety system that protects you in an emergency, and it works without any action on your part.

Why does the control unit 77960-TEA-M910-M4 fail?

In the 77960-TEA-M910-M4, stored crash data from an accident comes first, even if no airbag has triggered; a normal diagnostic tool cannot erase it. Other causes are aged components, cold solder joints, moisture at plug connections and voltage spikes.

Airbag24 removes the crash data as part of the repair. A normal diagnostic tool is not an option for this.

The other causes lie in the component or at the connections. Electronics age, solder joints can go cold, moisture and corrosion clog plug connections, and voltage spikes arise, for example with a weak battery or a jump-start.

How can you tell that the 77960-TEA-M910-M4 is defective?

On the 77960-TEA-M910-M4, a defect shows up as the airbag warning light in the instrument cluster, as error messages there, as a missing connection to the diagnostic tool and as a fault memory that cannot be erased.

These signs specifically indicate:

• airbag warning light on permanently or intermittently
• error message in the instrument cluster
• diagnostic tool does not find the control unit
• fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then not trigger.
