Airbag control unit with part number 77960-SNB-U622-M1

What does the airbag control unit 77960-SNB-U622-M1 do?

The airbag control unit 77960-SNB-U622-M1 is the restraint system (SRS) control unit for Honda. It processes the signals from the crash sensors, decides within milliseconds during an impact which airbags and seatbelt pretensioners fire, and monitors the system continuously. It reports faults via the airbag warning light.

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

Monitoring takes place throughout all operation, including when the vehicle is stationary.

Why does the control unit 77960-SNB-U622-M1 fail?

The most common cause is crash data from an accident, even when no airbag was triggered, and a standard diagnostic tool cannot delete it. Aged components, cold solder joints, moisture and voltage spikes are also possible causes.

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

Airbag24 deletes the crash data during the repair and at the same time checks the other causes.

How can you tell that the 77960-SNB-U622-M1 is defective?

On the 77960-SNB-U622-M1, the airbag warning light is usually the first sign to notice, whether it stays on permanently or intermittently. Added to this are an error message in the instrument cluster, a lost connection to the diagnostic tool and a fault memory that cannot be cleared.

With these signs, airbags and seatbelt pretensioners may not deploy in an emergency. Take the warning light seriously and have the system examined promptly.
