Airbag control unit with part number 77960-TK6-A011-M1

What does the airbag control unit 77960-TK6-A011-M1 do?

The airbag control unit 77960-TK6-A011-M1 coordinates the processes in the restraint system (SRS) for Honda. It reads the signals from the crash sensors and decides in an accident, within milliseconds, on airbags and seatbelt pretensioners. After an accident, it stores crash data and locks itself.

The unit detects faults in the system independently and displays them on the airbag warning light in the instrument cluster.

Seatbelt pretensioners are also controlled via the control unit, so faults affect both areas.

Why does the control unit 77960-TK6-A011-M1 fail?

Faults on the 77960-TK6-A011-M1 most often arise from crash data stored after an accident, even if no airbag has deployed. Further causes come from the electronics and their surroundings.

• aging components in the electronics
• cold solder joints
• moisture and corrosion on connectors
• voltage spikes, for example from a weak battery or jump-starting

Crash data cannot be removed with an ordinary diagnostic tool.

Which of these causes applies to the individual unit can only be determined by a test.

How can you tell that the 77960-TK6-A011-M1 is defective?

A defect in the 77960-TK6-A011-M1 can be recognised by the airbag warning light in the instrument cluster, which lights up permanently or intermittently, and by a fault message in the instrument cluster. A diagnostic tool without a connection to the control unit, or a fault memory that cannot be erased, also indicates the fault.

The warning light thus signals a fault in the restraint system. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

A timely test is therefore advisable.

Which vehicles is the 77960-TK6-A011-M1 fitted in?
