Airbag control unit with part number 77960-T5A-P410-M2

What does the airbag control unit 77960-T5A-P410-M2 do?

The airbag control unit 77960-T5A-P410-M2 belongs to the restraint system (SRS) of Honda. From the signals of the crash sensors it calculates in an accident which airbags and seatbelt pretensioners trigger, and it does so in milliseconds. It indicates faults in the system via the airbag warning light.

During operation the unit checks the entire system. As long as there is no fault, this work remains invisible to you.

After an accident the control unit stores crash data and locks itself. The further sections explain how this affects diagnosis and repair.

Why does the control unit 77960-T5A-P410-M2 fail?

For 77960-T5A-P410-M2, the most common cause after an accident is stored crash data, even when no airbag was triggered. They cannot be cleared with a standard diagnostic tool. Ageing components, moisture, corrosion and voltage spikes are also possible.

The crash data stay in the unit after the accident, even when little can be seen on the bodywork.

Ageing electronic components and cold solder joints also belong to the other causes. Moisture and corrosion at plug connections can lead to failure just as voltage spikes can, for example with a weak battery or jump-starting.

How can you tell that the 77960-T5A-P410-M2 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently in the event of a defect in the 77960-T5A-P410-M2. In addition, a fault message in the instrument cluster, a missing connection of the diagnostic tool and a fault memory that cannot be cleared may appear. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The light is the warning signal you should take seriously, even when the vehicle continues to drive normally.

If you notice one of these signs, have the fault memory read out. The log shows which entries the control unit has stored.
