Airbag control unit with part number 77960-TBA-A060-M2

What does the airbag control unit 77960-TBA-A060-M2 do?

The airbag control unit 77960-TBA-A060-M2 is the central control unit of the restraint system (SRS) for Honda. It evaluates the crash sensors, determines in a crash within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It indicates faults via the airbag warning light. After a crash, it stores crash data and locks itself.

During driving, the unit checks sensors, wiring and the activation of the restraint devices. Every detected deviation is stored in the fault memory.

If the warning light stays off, the control unit has reported no fault. If it lights up, a detected fault exists that must be checked.

Why does the control unit 77960-TBA-A060-M2 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. Other possible causes include aged electronic components, cold solder joints, moisture and corrosion at connectors, and voltage spikes, for example from a weak battery or jump-starting.

Crash data are records that the unit creates after an impact. A normal diagnostic tool cannot delete them. Airbag24 deletes them during the repair.

The other causes act over time and through the environment. Electronic components age, solder joints can turn cold and unreliable, and moisture with corrosion attacks plug contacts. Voltage spikes add further strain.

How can you tell that the 77960-TBA-A060-M2 is defective?

The airbag warning light in the instrument cluster is on permanently or intermittently, an error message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

These signs occur individually or together. The warning light alone is a clear signal that something in the system is wrong.

In an emergency, airbags and seatbelt pretensioners may not trigger in the event of a defect. It is therefore advisable to have the fault memory read out promptly.
