Airbag control unit with part number 77960-TV0-E010-M4

What does the airbag control unit 77960-TV0-E010-M4 do?

The airbag control unit 77960-TV0-E010-M4 is the central control unit of the restraint system (SRS) for Honda. It evaluates the signals from the crash sensors and, in a crash, decides within milliseconds which airbags and seatbelt pretensioners are triggered. It shows faults via the airbag warning light.

The unit monitors the system continuously. After an accident it stores crash data and locks itself.

Why does the control unit 77960-TV0-E010-M4 fail?

The most common cause is stored crash data after an accident, even if no airbag has deployed. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, as well as voltage spikes.

Crash data cannot be erased with a standard diagnostic tool. Airbag24 erases it during the repair.

The other causes relate to ageing, poor contacts and electrical stress, for example from a weak battery or jump-starting.

How can you tell that the 77960-TV0-E010-M4 is defective?

A defect in the 77960-TV0-E010-M4 shows itself through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Other signs include an error message, no connection to the diagnostic tool and a fault memory that cannot be cleared.

While the fault exists, airbags and seatbelt pretensioners may not be able to trigger in an emergency. For this reason, take the warning seriously and arrange a check promptly.
