Airbag control unit with part number 77960-SFY-J013-M1

What does the airbag control unit 77960-SFY-J013-M1 do?

The airbag control unit 77960-SFY-J013-M1 is responsible for the restraint system (SRS) of Honda. It processes the signals from the crash sensors, decides within milliseconds in an accident whether the airbags and seatbelt pretensioners are triggered, and monitors the system permanently. Following an accident, it stores crash data and locks itself.

The unit detects faults during ongoing monitoring and reports them via the airbag warning light in the instrument cluster. In doing so, it checks sensors, output stages and connections.

Why does the control unit 77960-SFY-J013-M1 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Other causes are ageing of the electronics, moisture and corrosion, cold solder joints and voltage spikes.

A diagnostic tool from a workshop does not clear this data. Airbag24 deletes it as part of the repair. Other causes at a glance:

• Electronic components age.
• Moisture and corrosion attack connectors.
• Cold solder joints lead to changing contact conditions.
• Voltage spikes, for example from a weak battery or a jump start.

How can you tell that the 77960-SFY-J013-M1 is defective?

A defect shows when the airbag warning light in the instrument cluster stays on permanently or flickers, fault messages appear, the diagnostic tool finds no connection to the control unit, or the fault memory cannot be cleared. In that case, airbags and seatbelt pretensioners may fail to deploy in an emergency.

A warning sign like this deserves a prompt check. The indicator remains meaningful even if the way the vehicle drives does not change. The cause is determined only by the readout and an inspection.

Which vehicles is the 77960-SFY-J013-M1 fitted in?

Comparing the part number on the label of the removed unit with this page will confirm whether you have the right unit. Whether the fault is in the unit itself is shown only by the readout of the fault memory, and that should be done before removal. A connector or a cable can also cause similar complaints.

How does the repair of the 77960-SFY-J013-M1 work?

First have the fault memory read out and attach the log. Then disconnect the battery, and only afterwards remove the control unit, and only then create the repair order online and send the unit. Processing at Airbag24 usually takes 3–4 working days.

There the unit is checked, components are replaced where necessary, crash data is deleted and the function is tested. After the test, your own repaired unit returns to you.

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-SFY-J013-M1 get to Airbag24?

You send the unit yourself as a package, or you book a UPS collection for an extra charge. The return after the repair is made by UPS.

The printed repair order belongs in the package. Pack the control unit so it withstands knocks and arrives undamaged.
