Airbag control unit with part number 77960-SZA-X120-M1

What does the airbag control unit 77960-SZA-X120-M1 do?

The airbag control unit 77960-SZA-X120-M1 processes the measured values from the crash sensors and decides in an accident which airbags and seatbelt pretensioners are triggered. It is responsible for the entire restraint system of Honda.

The unit monitors the system continuously and indicates faults via the airbag warning light in the instrument cluster.

After an accident, it stores crash data in memory and locks itself.

Why does the control unit 77960-SZA-X120-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. In addition, aged electronics, cold solder joints, moisture and corrosion at connectors, and voltage spikes are suspected.

Crash data does not only arise when an airbag has deployed. Storage is therefore independent of whether airbags actually fire.

Aged components and cold solder joints are also among the causes.

Voltage spikes, for example from a weak battery or a jump start, place additional strain on the electronics.

How can you tell that the 77960-SZA-X120-M1 is defective?

An error message in the instrument cluster, an airbag warning light that stays on permanently or intermittently, and a diagnostic tool without a connection to the control unit indicate a defect. Added to this is a fault memory that cannot be cleared. In this state, the airbags and seatbelt pretensioners may not deploy in an emergency.

The light is a clear signal from the control unit, which you should keep an eye on while driving. That means: this is not a detail to be overlooked.

An error message alone does not say where the fault lies; only the fault memory shows that.

Have the fault memory read out before removal, because only this log shows whether the control unit is defective or whether a connector or cable is the cause. Then compare the part number on the label with this page; this only confirms that it is the correct unit.

How does the repair of the 77960-SZA-X120-M1 work?

You have the fault memory read out first and enclose the log with the unit; then you disconnect the battery and remove the control unit. Afterwards you create a repair order online and send the unit in well packed. Airbag24 checks it, repairs defective components, erases the stored crash data and carries out a function test before your own unit is returned.

The sequence is mandatory for safety reasons and must not be changed.

Checking, repairing and testing at Airbag24 usually takes 3–4 working days.

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-X120-M1 get to Airbag24?

You can send the unit as a parcel or book a UPS collection for an extra charge. It comes back to you by UPS after the repair.

Pack it shock-proof and enclose the printed repair order; nothing else needs attention when shipping.
