Airbag control unit with part number 77960-T5A-J810-M1

What does the airbag control unit 77960-T5A-J810-M1 do?

The airbag control unit 77960-T5A-J810-M1 controls the restraint system (SRS) of the Honda. It evaluates the crash sensors, decides within milliseconds in a crash whether airbags and seatbelt pretensioners are triggered, and monitors the entire system.

The unit shows faults via the airbag warning light, which is immediately visible in the instrument cluster.

After an accident it stores crash data and locks itself. In everyday language it is also called the SRS control unit.

Why does the control unit 77960-T5A-J810-M1 fail?

Stored crash data is the most common cause, even if no airbag has deployed. Other causes affecting the electronics can also apply.

Crash data cannot be removed with a standard diagnostic tool. Airbag24 clears it during the repair.

The other causes in brief:

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

How can you tell that the 77960-T5A-J810-M1 is defective?

A defect shows up as the airbag warning light staying on permanently or intermittently, as an error message in the instrument cluster, as a diagnostic tool without connection, and as a fault memory that cannot be cleared.

Typical signs:

• warning light on permanently or intermittently
• error message in the instrument cluster
• no connection to the diagnostic tool
• fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may fail to deploy. Have the system checked promptly.
