Airbag control unit with part number 77960-SKN-G014-M1

What does the airbag control unit 77960-SKN-G014-M1 do?

The airbag control unit 77960-SKN-G014-M1 is the central control unit of the restraint system (SRS) of Honda. It evaluates the signals from the crash sensors, decides in an accident within fractions of a second which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it locks itself; this lock is lifted only by the repair.

The control unit reports faults via the airbag warning light in the instrument cluster. Notices that the system passes on to the driver also appear there.

The seatbelt pretensioners are controlled by the same control unit. The function of several protective elements therefore depends on a single unit, which is why its condition is so important for safety in the vehicle.

Why does the control unit 77960-SKN-G014-M1 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are also possible.

The crash data remain in the memory of the control unit, and only a repair removes it. They are stored there even if no airbag was triggered during the event.

The other causes also occur without an accident:

• aged electronic components on the circuit board
• cold solder joints that give way under load
• moisture and corrosion at plug connections
• voltage spikes, for example with a weak battery or after a jump start

How can you tell that the 77960-SKN-G014-M1 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, an error message appears in the instrument cluster, the diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared.

The airbag warning light may at first only come on intermittently and then stay on permanently. At the same time, the instrument cluster shows an error message that does not go away by restarting the ignition.

If no connection can be made to the diagnostic tool, or the fault memory stays full despite an attempt to clear it, there is a problem with the control unit or its connection. In this state, airbags and seatbelt pretensioners may fail to deploy in an emergency. A prompt check is therefore important.

The following applies to the assignment. Comparing the part number on the label of the removed unit with this page only ensures that it is the right unit. Also have the fault memory read out before you remove anything, because only the log shows whether the control unit is defective or whether a connector or cable is the cause.

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-G014-M1 work?

First read out the fault memory and enclose the log, then disconnect the battery and only then remove the control unit 77960-SKN-G014-M1. Next, create the repair order online and send the unit in well packed. Processing at Airbag24 usually takes 3–4 working days.

The sequence serves safety: only once the log is secured is the battery disconnected and the control unit removed. After that, the work at Airbag24 begins.

On the test bench, Airbag24 checks the unit, renews defective components, erases the stored crash data and carries out a function test. Afterwards your own, repaired unit goes back 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-SKN-G014-M1 get to Airbag24?

You send the unit in as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 sends it back by UPS.

Enclose the printed repair order in the parcel and pack the unit shock-proof.
