Airbag control unit with part number 77960-T2A-N060-M1

What does the airbag control unit 77960-T2A-N060-M1 do?

The airbag control unit 77960-T2A-N060-M1 forms the central control unit of the restraint system (SRS) of Honda. It evaluates the signals from the crash sensors and decides within a fraction of a second in a crash which airbags and seatbelt pretensioners are triggered.

The unit monitors the system continuously and shows detected faults via the airbag warning light. To do so, it checks connections and connected components continuously, even when no crash occurs.

After a crash, the control unit stores crash data and locks itself.

Why does the control unit 77960-T2A-N060-M1 fail?

Stored crash data after a crash is the most common cause of failure of the 77960-T2A-N060-M1, even if no airbag has deployed. Other causes are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

A normal diagnostic tool cannot delete this crash data. Airbag24 deletes it during the repair.

Aged components and cold solder joints show up over time, while moisture corrodes plug contacts. A voltage spike arises, for example, from a weak battery or when a jump start is connected. Only the examination of the unit shows whether one of these causes is present.

How can you tell that the 77960-T2A-N060-M1 is defective?

A defect in the 77960-T2A-N060-M1 shows primarily through the airbag warning light in the instrument cluster. Further warnings may appear, individually or together.

• The airbag warning light stays on permanently or intermittently.
• An error message appears in the instrument cluster.
• The diagnostic tool cannot connect to the control unit.
• The fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then be unable to deploy. This also applies if the vehicle drives normally in everyday use. Please have the warnings checked promptly.
