Airbag control unit with part number 77960-SNB-G222-M1

What does the airbag control unit 77960-SNB-G222-M1 do?

Within the restraint system (SRS) of Honda, the control unit 77960-SNB-G222-M1 takes over central control. It evaluates the crash sensors, decides in a crash within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It reports faults via the airbag warning light.

During operation, the electronics check the connections to the sensors and triggers.

After an accident, the unit stores crash data and locks itself.

Why does the control unit 77960-SNB-G222-M1 fail?

Most often, the cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Further causes are aged components, cold solder joints, moisture and corrosion, and voltage spikes.
