Airbag control unit with part number 77960-T5A-E010-M1

What does the airbag control unit 77960-T5A-E010-M1 do?

The airbag control unit 77960-T5A-E010-M1 controls the restraint system (SRS) in Honda vehicles. It processes the crash sensor signals and, in an impact, determines within milliseconds which airbags and seatbelt pretensioners fire.

The unit monitors the system continuously during operation. It stores detected faults in the fault memory and reports them via the airbag warning light.

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

Why does the control unit 77960-T5A-E010-M1 fail?

Crash data stored after an accident is the most frequent cause, even if no airbag has deployed. 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 a jump start

Crash data cannot be erased with an ordinary diagnostic tool. Airbag24 erases it during the repair.

How can you tell that the 77960-T5A-E010-M1 is defective?

A defect shows up as the airbag warning light staying on permanently or intermittently, an error message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

• Airbag warning light stays on permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool gets no connection to the control unit
• Fault memory cannot be cleared

If you notice any of these signs, have the system checked promptly. In an emergency, airbags and seatbelt pretensioners may not be triggered.
