Airbag control unit with part number 77960-T2A-Q912-M1

What does the airbag control unit 77960-T2A-Q912-M1 do?

The airbag control unit 77960-T2A-Q912-M1 ensures that the restraint system (SRS) responds at the right moment in Honda. From the signals of the crash sensors it recognises an impact and triggers airbags and seatbelt pretensioners within milliseconds.

During operation it checks the system and shows faults via the airbag warning light.

After an accident it stores crash data and locks itself.

Why does the control unit 77960-T2A-Q912-M1 fail?

With the 77960-T2A-Q912-M1, stored crash data causes the most problems, even if no airbag has been triggered. Beyond that, further causes in the electronics come into consideration.

• aged components
• cold solder joints
• moisture and corrosion on plug connectors
• voltage spikes

A normal diagnostic tool cannot erase the crash data. During the repair, Airbag24 removes it.

Voltage spikes arise, for example, from a weak battery or from jump-starting.

How can you tell that the 77960-T2A-Q912-M1 is defective?

A defect in the 77960-T2A-Q912-M1 shows itself through the airbag warning light, which stays on permanently or intermittently. Also possible are a fault notice in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be cleared.

• airbag warning light, permanently or intermittently
• fault message in the instrument cluster
• no connection between the diagnostic tool and the control unit
• fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. Take such signs seriously.
