Airbag control unit with part number 77960-T5A-F610-M1

What does the airbag control unit 77960-T5A-F610-M1 do?

The control unit 77960-T5A-F610-M1 controls the restraint system (SRS) in Honda vehicles. It evaluates the crash sensors, decides in a crash within milliseconds on triggering airbags and seatbelt pretensioners, and reports faults via the airbag warning light.

During operation the unit monitors the connected sensors and firing circuits without interruption.

After an accident it records crash data and then locks itself.

Why does the control unit 77960-T5A-F610-M1 fail?

The cause is most often found in stored crash data, even where no airbag has deployed; it cannot be removed with a standard diagnostic tool. Ageing components, moisture and voltage spikes are further factors.

The crash data remains in the memory until Airbag24 erases it during the repair. An ordinary intervention with the diagnostic tool is not enough for this.

The other causes include the following:

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

Which cause applies in an individual case only becomes clear from the inspection in our workshop.

How can you tell that the 77960-T5A-F610-M1 is defective?

A defect shows as an airbag warning light in the instrument cluster that lights up continuously or intermittently. Added to this are error messages, a lack of contact between the diagnostic tool and the control unit, and a fault memory that cannot be erased.

The light shows the defect directly. Ignoring it means accepting a known risk.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger.
