Airbag control unit with part number 77960-TG7-Y210-M2

What does the airbag control unit 77960-TG7-Y210-M2 do?

The airbag control unit 77960-TG7-Y210-M2 evaluates the signals of the crash sensors in the restraint system (SRS) for Honda. In a collision it decides within milliseconds which airbags and seatbelt pretensioners are triggered.

Monitoring of the system continues even without an accident. If the control unit detects a fault, it indicates this via the airbag warning light in the instrument cluster.

After an accident it stores crash data and locks itself. This lock is lifted only by a repair.

Why does the control unit 77960-TG7-Y210-M2 fail?

Most often the cause is stored crash data, even if no airbag has triggered. A normal diagnostic tool cannot remove it from the 77960-TG7-Y210-M2. Other causes include ageing, cold solder joints, moisture and voltage spikes.

The other causes are listed individually here:

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

Airbag24 erases the crash data during the repair. Reading out the fault memory beforehand is not affected by this and is still worthwhile.

How can you tell that the 77960-TG7-Y210-M2 is defective?

A defect in the 77960-TG7-Y210-M2 shows itself through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In addition there is an error message in the instrument cluster, and the diagnostic tool gets no connection to the control unit.

It is also conspicuous if the fault memory cannot be cleared. Each of these signs is reason enough to have the system checked, even if the light only comes on now and then.

In an emergency, airbags and seatbelt pretensioners may then not trigger. Therefore have the system checked as soon as one of these signs appears.
