Airbag control unit with part number 77960-T5A-G020-M1

What does the airbag control unit 77960-T5A-G020-M1 do?

The airbag control unit 77960-T5A-G020-M1 controls the restraint system of Honda. It evaluates the crash sensors, determines in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and reports faults via the airbag warning light.

The unit monitors the system continuously and works in the background. After an accident it stores crash data and locks itself.

Why does the control unit 77960-T5A-G020-M1 fail?

On the 77960-T5A-G020-M1, the most common cause is crash data stored after an accident, even if no airbag has deployed. These cannot be erased with a normal diagnostic tool. Other causes in brief:

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

Airbag24 erases the crash data during the repair. The other points concern the electronics and their connections.

How can you tell that the 77960-T5A-G020-M1 is defective?

On the 77960-T5A-G020-M1, the airbag warning light stays on permanently or intermittently, an error message appears in the instrument cluster, the diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared.

The warning light is the clearest sign of a problem with the control unit. In an emergency, airbags and seatbelt pretensioners may then possibly not trigger.

A missing connection to the diagnostic tool is also a sign that calls for a check.
