Airbag control unit with part number 77960-TG1-N410-M2

What does the airbag control unit 77960-TG1-N410-M2 do?

The control unit 77960-TG1-N410-M2 manages the restraint system (SRS) in Honda vehicles. It reads the sensors, determines in a crash which airbags and seatbelt pretensioners are triggered, and monitors the system permanently. It reports anomalies via the airbag warning light.

The evaluation takes place within a fraction of a second.

After an accident, the unit stores crash data; after that it is locked.

Why does the control unit 77960-TG1-N410-M2 fail?

The most common reason for problems with the 77960-TG1-N410-M2 is stored crash data, even when no airbag has deployed. An ordinary diagnostic tool cannot erase it. In addition, aged electronics, cold solder joints, moisture and corrosion on plugs, as well as voltage spikes may play a role.

The data arises inside the unit, and Airbag24 removes it as part of the repair.

The other causes are ageing of the electronics, cold solder joints, moisture, corrosion and voltage spikes from weak batteries or jump-starting.

How can you tell that the 77960-TG1-N410-M2 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently when the 77960-TG1-N410-M2 is defective. If a fault message, a diagnostic tool without connection or a fault memory that will not clear also appear, the evidence builds up. Airbags and seatbelt pretensioners may then possibly fail to trigger in an emergency.

You should take this signal seriously, because it affects the entire restraint system.

The warning light is the sign you notice first.
