Airbag control unit with part number 77960-T6A-H730-M2

What does the airbag control unit 77960-T6A-H730-M2 do?

The airbag control unit 77960-T6A-H730-M2 manages the restraint system (SRS) in Honda. The crash sensors supply it with measurement data; from that it decides within milliseconds which airbags and seatbelt pretensioners trigger, and it monitors the system without interruption. After an accident it stores crash data and locks itself.

If the control unit detects a fault, it indicates this via the airbag warning light in the instrument cluster.

Why does the control unit 77960-T6A-H730-M2 fail?

Stored crash data from an accident is the most common cause of the problem, even when no airbag has deployed. A standard diagnostic tool cannot erase it; during repair, Airbag24 removes it. Ageing components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes can also play a role.

The crash data remain in the control unit's memory until the repair clears them. Whether one of the other causes applies only becomes clear when the fault memory is read out together with an inspection of the unit.

How can you tell that the 77960-T6A-H730-M2 is defective?

A defect shows up as messages from the airbag warning light that stay on constantly or light up intermittently. In an emergency, the airbags and seatbelt pretensioners may then fail to deploy.

• Airbag warning light stays on constantly
• Airbag warning light comes on intermittently
• Fault message in the instrument cluster
• Diagnostic tool does not find the control unit
• Fault memory cannot be cleared

Note the messages with dates before you visit a workshop.
