Airbag control unit with part number 77960-T7A-E110-M2

What does the airbag control unit 77960-T7A-E110-M2 do?

The airbag control unit 77960-T7A-E110-M2 is the control unit of the restraint system (SRS) for Honda. It evaluates the crash sensors and decides in an accident, within milliseconds, which airbags and seatbelt pretensioners are triggered.

It also monitors the system continuously. Faults are displayed via the airbag warning light in the instrument cluster.

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

Why does the control unit 77960-T7A-E110-M2 fail?

Stored crash data is the most common cause with the 77960-T7A-E110-M2, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Other causes include aged components, cold solder joints, corrosion on plug connectors and voltage spikes.

The data remains in memory until Airbag24 removes it during the repair. Whether it alone causes the failure, or whether one of the other causes is added, is shown by the inspection.

Moisture on the plugs and voltage spikes, for example from a weak battery or a jump start, are also among the causes.

How can you tell that the 77960-T7A-E110-M2 is defective?

On the 77960-T7A-E110-M2, a defect shows up through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In an emergency, airbags and seatbelt pretensioners may then not deploy.

• Fault message in the instrument cluster
• No connection between the diagnostic tool and the control unit
• Fault memory that cannot be cleared

As soon as one of these signs appears, have the system checked. The light shows the defect clearly.
