Airbag control unit with part number 77960-SKN-G811-M1

What does the airbag control unit 77960-SKN-G811-M1 do?

The airbag control unit 77960-SKN-G811-M1 is responsible for the restraint system of Honda. It analyses the crash sensors in the event of an impact, decides within milliseconds whether airbags and seatbelt pretensioners trigger, and monitors the system during operation. It shows faults via the airbag warning light.

The system checks itself constantly. The control unit monitors sensors, wiring and trigger circuits, and any faults it detects end up in the fault memory.

After an accident the unit records crash data and locks itself. Keep this in mind with every warning.

Why does the control unit 77960-SKN-G811-M1 fail?

The most common cause is crash data from an accident, which is stored even if no airbag has triggered. Aged components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes, for example from a weak battery or jump-starting, are also possible causes.

A standard diagnostic tool cannot remove this crash data. Airbag24 clears it during the repair. The other causes in detail:

• aged electronic components
• cold solder joints in the unit
• moisture and corrosion in plug connections
• voltage spikes, for example from a weak battery or jump-starting

How can you tell that the 77960-SKN-G811-M1 is defective?

A defect shows itself through an airbag warning light that stays on permanently or intermittently, through a fault message in the instrument cluster, or through a diagnostic tool that cannot make contact with the control unit. In addition, a fault memory may not be clearable. In that case, airbags and seatbelt pretensioners may possibly fail to trigger in an emergency.

The warning light in the instrument cluster deserves particular attention, because it reports the fault immediately once the control unit detects it.

Have such indications checked promptly, rather than waiting for a later opportunity.

Hold the part number on the removed unit next to this page, and you will see whether it is the right unit. The condition of the control unit is shown only by the fault memory. It also clarifies whether a plug or cable is responsible for the fault.

For the same vehicles, we also repair control units with the part numbers 77960-SWA-G214-M4, 77960-SWA-S21, 77960-SWA-S214-M4, 77960-T0AA-110-M1, 77960-TA0-A031, 77960-TLA-A25.

How does the repair of the 77960-SKN-G811-M1 work?

First have the fault memory read out, then disconnect the battery and only afterwards remove the control unit. Then create a repair order online, enclose the protocol and send the well-packed unit.

Checking, repairing and testing at Airbag24 usually take 3–4 working days. There the unit goes on the test bench, defective components are replaced, the crash data is erased and a function test is carried out.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 77960-SKN-G811-M1 get to Airbag24?

You send the unit yourself in a parcel, or alternatively you book a UPS collection for an extra charge. After the repair, the return is also made by UPS.

Pack the unit shock-proof and enclose the printed repair order.
