Airbag control unit with part number 77960-T5A-C210-M1

What does the airbag control unit 77960-T5A-C210-M1 do?

The airbag control unit 77960-T5A-C210-M1 coordinates the restraint system (SRS) in Honda. It checks the messages from the crash sensors, determines in a crash within a few milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

If a fault is detected, the unit reports it via the airbag warning light in the instrument cluster. In addition, after an accident it stores crash data and locks itself.

Why does the control unit 77960-T5A-C210-M1 fail?

Crash data that remains stored in the unit after an accident is the most common cause, even if no airbag has triggered. A standard diagnostic tool cannot remove it. Aged electronics, cold solder joints, moisture or corrosion on plug connections and voltage spikes are also possible causes.

That no airbag has fired therefore does not rule out storage.

Ageing and environmental influences add to this: electronic components lose reliability over time, and moisture attacks plug connections. Voltage spikes also belong here, because a weak battery or a jump start can damage the electronics.

How can you tell that the 77960-T5A-C210-M1 is defective?

The airbag warning light in the instrument cluster lights up permanently or only intermittently, an error message appears, and the diagnostic tool cannot reach the control unit. If the fault memory cannot be cleared, this sign is added. With these signs, airbags and seatbelt pretensioners may not trigger in an emergency.

The light is a warning that must be taken seriously, even if the vehicle otherwise drives normally.

An error message alone does not reveal the cause. Only evaluating the fault memory shows whether the control unit itself or a plug is affected.

Compare the part number on the removed unit with this page; this only shows that it is the right unit. Have the fault memory read out beforehand, because only this log reveals whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 77960-T5A-A212-M1, 77960-T5A-E010-M1, 77960-T5A-E011-M1, 77960-T5A-E020-M1, 77960-T5A-F010-M1, 77960-T5A-F011-M1.

How does the repair of the 77960-T5A-C210-M1 work?

You first read out the fault memory, enclose the log, disconnect the battery and only then remove the control unit; afterwards create a repair order online. Airbag24 checks the unit, repairs defective components, deletes the crash data and tests the function; processing usually takes 3–4 working days.

The sequence serves safety, which is why the battery is disconnected before removal.

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-T5A-C210-M1 get to Airbag24?

The unit reaches Airbag24 by post as a parcel or by a booked UPS collection (for an extra charge). UPS takes care of the return after the repair.

Make sure the packaging is shockproof and enclose the printed repair order.
