What does the airbag control unit 77960-TVA-Z020-M4 do?
The airbag control unit 77960-TVA-Z020-M4 is the control unit that coordinates the restraint system (SRS) of Honda. It processes the measured values of the crash sensors, determines within milliseconds which airbags and seatbelt pretensioners are triggered, and checks the system continuously.
If it detects a fault, the airbag warning light becomes active. After an accident, it stores crash data and then locks itself.
Why does the control unit 77960-TVA-Z020-M4 fail?
Most often this is due to crash data stored after an accident, even if no airbag has triggered. A diagnostic tool in normal operation cannot remove them. In addition, there are aged components, cold solder joints, moisture at plug connectors and voltage spikes.
The crash data therefore remain in the unit, even if nothing conspicuous is visible afterwards.
Without an accident, these causes come into consideration:
- aged electronic components
- cold solder joints
- 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-TVA-Z020-M4 is defective?
If the airbag warning light in the instrument cluster lights up, a warning message appears, the diagnostic tool cannot reach the control unit, or the fault memory cannot be erased, a defect is likely. Airbags and seatbelt pretensioners may then not trigger in an emergency.
The light is the first and clearest indication the vehicle gives. Therefore have the vehicle read out at a workshop promptly.
