Airbag control unit with part number 77960-TGH-K810-M2

What does the airbag control unit 77960-TGH-K810-M2 do?

The airbag control unit 77960-TGH-K810-M2 acts as the central unit that controls the restraint system (SRS) of Honda. Using the crash sensors, it measures what happens in an accident and decides within milliseconds which airbags and seatbelt pretensioners are triggered. It monitors all components without pause.

It shows a fault via the airbag warning light in the instrument cluster.

An accident leaves crash data in the unit, after which it locks itself.

Why does the control unit 77960-TGH-K810-M2 fail?

With this 77960-TGH-K810-M2, the most common cause of a failure is crash data stored after an accident, even if no airbag was triggered. Other causes are ageing components, cold solder joints, moisture and corrosion, and voltage spikes.

Stored crash data remain in the control unit, and an ordinary diagnostic tool does not remove them. During the repair, Airbag24 erases this data.

The other causes are linked to ageing and the environment: electronic components become prone to faults over time, solder joints can be poorly connected, and moisture attacks plug connections. 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-TGH-K810-M2 is defective?

You recognise a defect in the 77960-TGH-K810-M2 by the airbag warning light in the instrument cluster, which stays on permanently or intermittently. In addition, you see an error message, and the diagnostic tool finds no connection to the control unit.

Typical signs are:

• The airbag warning light stays on permanently or intermittently.
• An error message appears in the instrument cluster.
• A diagnostic tool gets no connection to the control unit.
• The fault memory cannot be erased.

In an emergency, the airbags and seatbelt pretensioners may then fail to trigger. Take this warning seriously and have the cause clarified promptly.
