Airbag control unit with part number 77960-SNB-T022-M1

What does the airbag control unit 77960-SNB-T022-M1 do?

In the restraint system (SRS) of Honda, the airbag control unit 77960-SNB-T022-M1 takes the decision on triggering. It processes the measured values of the crash sensors and determines in an impact, within milliseconds, which airbags and seatbelt pretensioners are triggered.

In addition comes continuous self-monitoring. If the unit notices a fault, the airbag warning light comes on.

After an accident it writes crash data and locks itself. Only the repair lifts the lock.

Why does the control unit 77960-SNB-T022-M1 fail?

The most common cause is that crash data was stored after an accident, even if no airbag has deployed. Other causes are aged components, cold solder joints, moisture in plugs, corrosion and voltage spikes.

Crash data cannot be removed with usual diagnostic tools. Airbag24 handles this as part of the repair.

How strongly the other factors play a role in the specific case remains open without testing.

How can you tell that the 77960-SNB-T022-M1 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. A fault message may also appear, the diagnostic tool cannot reach the control unit, and a fault memory cannot be cleared.

In an emergency, the airbags and seatbelt pretensioners may therefore not deploy. It is important not to ignore the light.
