Airbag control unit with part number 77960-SZA-X012-M1

What does the airbag control unit 77960-SZA-X012-M1 do?

The airbag control unit 77960-SZA-X012-M1 controls the restraint system (SRS) of Honda. From the signals of the crash sensors it calculates, within fractions of a second, whether airbags and seatbelt pretensioners must trigger.

At the same time it continuously checks the connected components for faults. If it detects a fault, the airbag warning light in the instrument cluster lights up so that you notice the finding immediately.

After an accident the unit stores crash data and then locks itself. This applies regardless of whether an airbag was triggered in the accident.

Why does the control unit 77960-SZA-X012-M1 fail?

Stored crash data is the most common cause, even when no airbag has deployed. Further possible causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes such as from a weak battery or a jump-start.

A standard diagnostic tool does not remove this data. Airbag24 erases it as part of the repair.

The other triggers are related to wear and environmental influences. Electronics that have been working for years and plug contacts where moisture causes corrosion are typical weak points.

How can you tell that the 77960-SZA-X012-M1 is defective?

A defect shows on the airbag warning light in the instrument cluster, which lights constantly or intermittently, and on an error message in the instrument cluster. In addition the diagnostic tool cannot establish a connection to the control unit, and the fault memory cannot be cleared.

Such signs must be taken seriously, because airbags and seatbelt pretensioners may possibly not deploy in an emergency. The warning light makes the finding visible, and a prompt check should follow.

Check the part number on the label of the removed unit and compare it with this page. This only ensures that it is the correct unit. Have the fault memory read out before removal, because only the result shows whether the control unit itself is defective or whether a plug or cable is the cause.

How does the repair of the 77960-SZA-X012-M1 work?

First have the fault memory read out and attach the log. Then disconnect the battery and only then remove the control unit, before creating a repair order online. Send the unit well packed; then Airbag24 checks it on the test bench, repairs defective components, erases stored crash data and carries out a function test.

After that the unit returns to you. The processing time at Airbag24 is usually 3–4 working days, and this period applies only to checking, repairing and testing at Airbag24.

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-SZA-X012-M1 get to Airbag24?

You send the unit as a parcel or arrange a UPS collection for an extra charge. After the repair Airbag24 sends it back to you by UPS.

Put the printed repair order into the parcel and pack the unit shock-proof.
