Airbag control unit with part number 77960-S6A-G941-M2

What does the airbag control unit 77960-S6A-G941-M2 do?

The airbag control unit 77960-S6A-G941-M2 controls the restraint system (SRS) of Honda. It evaluates the signals from the crash sensors, decides within milliseconds in a crash whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it stores crash data and locks itself.

Monitoring runs throughout every journey. The unit checks sensors, firing stages and the wiring to the triggers.

The control unit works in conjunction with sensors, wiring harness and display. A fault in any of these parts can therefore appear as an error in the control unit.

Why does the control unit 77960-S6A-G941-M2 fail?

The most common cause in the 77960-S6A-G941-M2 control unit is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase it. Other causes include aged components, cold solder joints, moisture and voltage spikes.

The possible causes in detail are:

• crash data stored after an accident, even without a deployed airbag
• aged electronic components
• cold solder joints on the circuit board
• moisture and corrosion at plug connectors
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 77960-S6A-G941-M2 is defective?

The airbag warning light in the instrument cluster lights up on the 77960-S6A-G941-M2 control unit permanently or intermittently, and a fault message appears in the instrument cluster. If the diagnostic tool cannot connect to the control unit and the fault memory cannot be cleared, a defect is likely. Airbags and seatbelt pretensioners may then fail to trigger in an emergency.

Typical signs at a glance:

• airbag warning light that stays on permanently or intermittently
• fault message in the instrument cluster
• no connection established to the diagnostic tool
• fault memory that cannot be cleared
