Airbag control unit with part number 77960-SHJ-X010-M1

What does the airbag control unit 77960-SHJ-X010-M1 do?

The airbag control unit 77960-SHJ-X010-M1 is the control unit of the restraint system (SRS) at Honda. It processes the signals from the crash sensors, determines in a crash which airbags and seatbelt pretensioners are triggered, and checks the system continuously. After an accident it stores crash data and locks itself.

The evaluation takes place in a very short time, because in an impact there is no time for delays.

The airbag warning light in the instrument cluster reports faults that the unit detects.

Why does the control unit 77960-SHJ-X010-M1 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. Erasing it with a normal diagnostic tool does not work; during repair, Airbag24 erases the data. Other causes are aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

The other causes in detail:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connectors
• voltage spikes, for example from jump starting

Which of these applies in the individual case only the examination will show.

How can you tell that the 77960-SHJ-X010-M1 is defective?

A defect shows up at the airbag warning light in the instrument cluster and in fault messages there. In addition, there are connection problems with the diagnostic tool and a fault memory that cannot be cleared.

• airbag warning light, permanently or intermittently
• fault message in the instrument cluster
• no connection established by the diagnostic tool to the control unit
• fault memory that cannot be cleared

In an emergency, the airbags and seatbelt pretensioners may not trigger when such a finding is present.

For that reason, have the system examined promptly and do not keep driving unchecked.
