Airbag control unit with part number 77960-T5A-E011-M1

What does the airbag control unit 77960-T5A-E011-M1 do?

The airbag control unit 77960-T5A-E011-M1 belongs to the restraint system (SRS) of Honda and is its central control unit. It reads the crash sensors, decides in an accident within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It shows reported faults via the airbag warning light.

The control unit works in the background and remains inconspicuous as long as operation is without faults.

After an accident, the unit stores crash data and locks itself.

Why does the control unit 77960-T5A-E011-M1 fail?

For 77960-T5A-E011-M1, crash data from an accident is the most common cause, even if no airbag was triggered. It cannot be removed with a standard diagnostic tool. Further causes include aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Airbag24 erases the crash data during the repair and checks the electronics for the other points.

These causes are possible in detail:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

Which of these applies is shown only by the inspection of the system.

How can you tell that the 77960-T5A-E011-M1 is defective?

You can recognise a defect on the 77960-T5A-E011-M1 by the airbag warning light in the instrument cluster, which lights up permanently or intermittently. A fault message or a fault memory that cannot be cleared also indicates the malfunction.

Typical signs are:

• airbag warning light lights up permanently or intermittently
• error message in the instrument cluster
• diagnostic tool gets no connection to the control unit
• fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may not trigger. Therefore, have the indication checked promptly.
