Airbag control unit with part number 77960-SNB-Y430-M1

What does the airbag control unit 77960-SNB-Y430-M1 do?

The airbag control unit 77960-SNB-Y430-M1 is part of the restraint system (SRS) of Honda and controls the airbags and seatbelt pretensioners. It takes readings from the crash sensors, decides within milliseconds what is triggered, and checks the system continuously.

It shows faults via the airbag warning light. After an accident it stores crash data and locks itself; the lock is only lifted by the repair.

Why does the control unit 77960-SNB-Y430-M1 fail?

The most common cause is crash data stored after an accident, even without an airbag having been triggered. A standard diagnostic tool cannot remove it. Other causes are aged electronics, cold solder joints, moisture or corrosion on connectors, and voltage spikes.

The crash data is only erased by the repair at Airbag24. Plugs and cables can also play a role.

Which of these causes applies to your vehicle only becomes clear once the fault memory has been read out.

How can you tell that the 77960-SNB-Y430-M1 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. Added to this are fault messages in the instrument cluster, or a diagnostic tool that cannot establish contact with the control unit.

• Airbag warning light stays on permanently or intermittently

• Diagnostic tool cannot establish contact with the control unit
• Fault memory remains after an attempt to clear it

With these signs, airbags and seatbelt pretensioners may not trigger in an emergency.

Only reading out the fault memory shows whether the control unit itself is affected.
