Airbag control unit with part number 77960-T5A-H611-M1

What does the airbag control unit 77960-T5A-H611-M1 do?

The airbag control unit 77960-T5A-H611-M1 processes the signals from the crash sensors at Honda and controls which airbags and seatbelt pretensioners trigger in an accident. It monitors the entire restraint system continuously and reports faults via the airbag warning light.

The decision on triggering is made within milliseconds, that is, while the accident is still under way.

After an accident the control unit stores crash data and locks itself. Only the repair lifts the lock.

Why does the control unit 77960-T5A-H611-M1 fail?

The most common cause is crash data stored after an accident, even if no airbag has triggered. A normal diagnostic tool cannot delete it. Further causes are ageing of the electronics, solder joints, moisture and voltage spikes.

Airbag24 removes the crash data during the repair. The other causes at a glance:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a jump start or a weak battery

How can you tell that the 77960-T5A-H611-M1 is defective?
