Airbag control unit with part number 77960-SNB-J222-M1

What does the airbag control unit 77960-SNB-J222-M1 do?

The airbag control unit 77960-SNB-J222-M1 coordinates the restraint system (SRS) for Honda. It reads the crash sensors and determines which airbags and seatbelt pretensioners are triggered.

The electronics check the system continuously and report faults via the airbag warning light.

After an accident, the unit records crash data and locks itself.

Why does the control unit 77960-SNB-J222-M1 fail?

The most common cause is crash data after an accident, even if no airbag was triggered. Further triggers are aged electronics, dry solder joints, moisture and corrosion at plugs, and voltage spikes.

An ordinary diagnostic tool cannot erase the crash data. Airbag24 takes care of this during the repair.

The possible causes in detail are:

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

How can you tell that the 77960-SNB-J222-M1 is defective?

A defect in the 77960-SNB-J222-M1 is indicated by the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In addition there are fault messages in the instrument cluster, a missing connection to the diagnostic tool and a fault memory that cannot be cleared.

As long as these warning signs are present, airbags and seatbelt pretensioners may not trigger in an emergency. The warning light is therefore a sign you should not ignore.
