Airbag control unit with part number 77960-TR0-X013-M1

What does the airbag control unit 77960-TR0-X013-M1 do?

The airbag control unit 77960-TR0-X013-M1 controls the restraint system (SRS) for Honda. It checks the crash sensors continuously and decides in an accident, within milliseconds, whether airbags and seatbelt pretensioners are triggered. After an accident, it stores crash data and locks itself.

The control unit detects faults itself and reports them via the airbag warning light in the instrument cluster. Only the repair lifts the lock after an accident.

Why does the control unit 77960-TR0-X013-M1 fail?

With the 77960-TR0-X013-M1, the most common cause after an accident is stored crash data, even if no airbag has deployed. It cannot be deleted with a normal diagnostic tool. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes such as those from a weak battery or a jump start are also causes.

The entries remain in the memory until Airbag24 deletes them during the repair.
