Airbag control unit with part number 77960-TVE-H230-M4

What does the airbag control unit 77960-TVE-H230-M4 do?

The airbag control unit 77960-TVE-H230-M4 controls the SRS restraint system of Honda. It checks the signals from the crash sensors, decides in an accident which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident, it stores crash data and locks itself.

If the unit reports a fault, it appears on the airbag warning light in the instrument cluster. The warning light is therefore the first indication that something is wrong in the restraint system.

The control unit is connected to all sensors and triggering units, and it constantly checks exactly these connections.

Why does the control unit 77960-TVE-H230-M4 fail?

The most frequent trigger with the 77960-TVE-H230-M4 is crash data from an earlier accident, even if no airbag was triggered. Aged components, moisture at plug connections and voltage spikes can also lead to failure.

Crash data cannot be erased with a normal diagnostic tool. Airbag24 erases them during the repair.

Electronic components age, and solder joints can go cold or break. Moisture and corrosion at plug connections also have an effect, because they disturb the electrical contact.

A power surge, such as from a weak battery or jump starting, can additionally load the electronics. Which of these causes is actually present is only shown by testing the system.

How can you tell that the 77960-TVE-H230-M4 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and an error message appears. In addition, the diagnostic tool cannot connect to the 77960-TVE-H230-M4, or the fault memory cannot be cleared.
