Airbag control unit with part number 77960-T5A-T210-M2

What does the airbag control unit 77960-T5A-T210-M2 do?

The airbag control unit 77960-T5A-T210-M2 is the link between the crash sensors and the restraint devices of Honda. In an accident, it calculates which airbags and seatbelt pretensioners are to be triggered, and it monitors the entire system.

It reports anomalies via the airbag warning light in the instrument cluster. After an accident, it stores crash data and locks itself.

Why does the control unit 77960-T5A-T210-M2 fail?

Crash data from an accident is the most common cause, even if no airbag has deployed, and this data cannot be removed with a normal diagnostic tool. Other causes are ageing, cold solder joints, moisture and voltage spikes.

Storage happens regardless of whether the airbags deploy; the crash data nevertheless remains in the unit.

Over time, electronic components age, and solder joints can go cold.

Moisture and corrosion at plug connections disrupt the contact, while 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-T5A-T210-M2 is defective?

A defect is indicated by the airbag warning light in the instrument cluster, an error message and a missing connection to the diagnostic tool. If the fault memory cannot be cleared, this sign is added. In this state, the airbags and seatbelt pretensioners may not deploy in an emergency.

The typical signs at a glance:

• Airbag warning light that stays on permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool does not find the control unit
• Fault memory cannot be cleared

The warning light is a warning signal from the control unit itself, which should be taken seriously.

Comparing the part number on the label with this page only confirms the correct unit. The cause is only determined by the fault memory, which you have read out before removal; only it shows whether the control unit is defective or whether a connector or cable is affected.

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-T210-M2 work?

To begin with, the fault memory is read out with the log enclosed; then you disconnect the battery and remove the control unit, and you create the repair order online. Airbag24 tests it on the test bench, repairs defective components, erases the crash data and carries out a function test; this usually takes 3–4 working days.

The battery is disconnected before removal, because safety takes precedence in this way.

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-T210-M2 get to Airbag24?

You send the control unit as a parcel to Airbag24, or have it collected by UPS for an extra charge. The return after repair is also handled by UPS.
