Airbag control unit with part number 77960-SWA-Y811-M1

What does the airbag control unit 77960-SWA-Y811-M1 do?

At Honda, the airbag control unit 77960-SWA-Y811-M1 controls the SRS restraint system. From the data of the crash sensors it determines in an impact which airbags and seatbelt pretensioners are triggered. After an accident it stores crash data and locks itself.

During operation it monitors the system and indicates detected faults via the airbag warning light.

Why does the control unit 77960-SWA-Y811-M1 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. Other causes lie in aging, moisture and voltage spikes.

Crash data remains stored, because a normal diagnostic tool does not erase it. The other causes in detail:

• Aging electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or a jump start
