Airbag control unit with part number 77960-T00-D610-M2

What does the airbag control unit 77960-T00-D610-M2 do?

The airbag control unit 77960-T00-D610-M2 belongs to the restraint system (SRS) of Honda and forms its control centre. It evaluates the signals from the crash sensors and in a crash decides within milliseconds which airbags and seatbelt pretensioners are triggered.

It monitors the system permanently and indicates faults via the airbag warning light. After a crash it stores crash data and locks itself.

Only a repair lifts the lock.

Why does the control unit 77960-T00-D610-M2 fail?

Crash data stored after an earlier accident is the most common cause of the 77960-T00-D610-M2 failing, even if no airbag was triggered. Added to this are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

Crash data cannot be erased with a standard diagnostic tool, which is why only the repair at Airbag24 helps. The data is erased there.

The other causes are ageing, connection problems caused by moisture and corrosion, and voltage spikes. Voltage spikes occur, for example, with a weak battery or a jump start.

How can you tell that the 77960-T00-D610-M2 is defective?

A defect on the 77960-T00-D610-M2 shows up in the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Also present are a fault message in the instrument cluster, a diagnostic tool without a connection to the control unit, and a fault memory that cannot be cleared.

In the event of such a defect, airbags and seatbelt pretensioners may not trigger in a crash.

If the warning light stays on, have the fault clarified.
