Airbag control unit with part number 77960-TR0-R010-M1

What does the airbag control unit 77960-TR0-R010-M1 do?

The airbag control unit 77960-TR0-R010-M1 is the control unit of the restraint system in vehicles from Honda. It evaluates the crash sensors, determines in the event of an accident within milliseconds whether airbags and seatbelt pretensioners are triggered, and checks its function continuously.

It shows the results of this monitoring via the airbag warning light. In addition, there is a memory that records crash data if an accident occurs.

After an accident, the unit locks itself. The lock is lifted by the repair.

Why does the control unit 77960-TR0-R010-M1 fail?

Stored crash data is the most common cause of the 77960-TR0-R010-M1 failing, even if no airbag has triggered; a normal diagnostic tool does not erase it. In addition, there are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or a jump start.

Crash data is therefore present even when the airbags have remained inactive. This must be checked first when looking for the fault.

The other causes are deliberately brief. Electronics age, solder joints can go cold, and moisture attacks contacts.

During the repair, Airbag24 removes the stored crash data.

How can you tell that the 77960-TR0-R010-M1 is defective?

The airbag warning light in the instrument cluster lights up on the 77960-TR0-R010-M1 permanently or intermittently. In addition, the instrument cluster shows a fault message, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared. Airbags and seatbelt pretensioners may then possibly not trigger in an emergency.

When you notice these signs, do not wait. A warning light that does not go out after starting deserves a prompt inspection.

Which component is affected is only shown by reading out the fault memory. The signs alone are not enough to determine the cause.

Which vehicles is the 77960-TR0-R010-M1 fitted in?

The 77960-TR0-R010-M1 is fitted in these vehicles: Honda Civic 9th generation (2011-2017).

The list contains the vehicles to which this part number is assigned:

• Honda Civic 9th generation (2011-2017)

Compare the part number on the label of the removed unit with this page, because this ensures that you have the right unit. Also have the fault memory read out before removal: only this result shows whether the control unit is defective or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 77960-TS4-U411-M1, 77960-TS4-U811-M2, 77960-TS4-Z611-M1, 77960-TS6-H711-M1, 77960-TT0-T011-M1, 77960-TT0-Y610-M2.

How does the repair of the 77960-TR0-R010-M1 work?

Have the fault memory read out first; the log goes with the unit. Only after the battery is disconnected do you remove the control unit 77960-TR0-R010-M1. The repair order is created online, after which the unit is sent off well packed.

Airbag24 then checks the unit on the test bench, repairs defective components and removes the stored crash data. A function test follows. Processing usually takes 3–4 working days; afterwards your own 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.
