Airbag control unit with part number 77960-TT0-T011-M1

What does the airbag control unit 77960-TT0-T011-M1 do?

The airbag control unit 77960-TT0-T011-M1 is the central control unit of the restraint system (SRS) for Honda. It evaluates the signals from the crash sensors, decides in an accident, within milliseconds, on the deployment of airbags and seatbelt pretensioners, and monitors the system continuously. After an accident, it stores crash data and locks itself.

If the control unit detects a fault, it indicates it via the airbag warning light in the instrument cluster.

Why does the control unit 77960-TT0-T011-M1 fail?

Crash data stored after an accident are the most common cause with the 77960-TT0-T011-M1, even if no airbag has triggered; other possible causes include aged components, moisture and voltage spikes. With this control unit, deleting the crash data is often not possible; if you want it deleted, get in touch with Airbag24 briefly before sending the unit in.

A normal diagnostic tool cannot delete crash data. This also applies if no airbag was triggered in the accident.

The other causes concern the electronics and their connections: aged components, cold solder joints, and moisture and corrosion on plug connections.

Voltage spikes, for example from a weak battery or a jump start, can also cause faults. Which cause applies is only shown by the examination.

How can you tell that the 77960-TT0-T011-M1 is defective?

The airbag warning light in the instrument cluster indicates a defect in the 77960-TT0-T011-M1 if it stays on permanently or intermittently. In addition, there may be a fault message in the instrument cluster, a missing connection between the diagnostic tool and the control unit, or a fault memory that cannot be cleared.

The light makes the defect visible. Nevertheless, have it checked promptly, as in an emergency airbags and seatbelt pretensioners may possibly not deploy.
