Airbag control unit with part number 77960-S5A-A930-M1

What does the airbag control unit 77960-S5A-A930-M1 do?

The airbag control unit 77960-S5A-A930-M1 is the central control unit of the restraint system (SRS) for Honda. From the signals of the crash sensors it calculates within milliseconds which airbags and seatbelt pretensioners fire in an accident. It monitors the system constantly and reports faults via the airbag warning light.

It works in the background throughout the entire journey and checks its connections in the process.

After an accident the control unit secures crash data and locks itself.

Why does the control unit 77960-S5A-A930-M1 fail?

On the 77960-S5A-A930-M1, the most common cause is crash data that remained stored after an accident, even if no airbag fired. A normal diagnostic tool cannot erase this data. Aged components, moisture at plug connectors, cold solder joints and voltage spikes are also possible causes.

Airbag24 takes over this step during the repair, so you do not have to carry it out yourself.

In everyday use, ageing and moisture play a role, as do voltage spikes that occur with a weak battery or after a jump start.

How can you tell that the 77960-S5A-A930-M1 is defective?

A defect on the 77960-S5A-A930-M1 shows mainly through the airbag warning light in the instrument cluster when it lights permanently or intermittently. A fault message, a missing connection to the diagnostic tool or a fault memory that cannot be erased are also signs.

• Airbag warning light on permanently or intermittently
• Fault message in the instrument cluster
• No connection between diagnostic tool and control unit
• Fault memory cannot be erased

The light indicates the defect as soon as the system detects it. A diagnostic tool then reads out the fault memory.

In an emergency, the airbags and seatbelt pretensioners may not be able to fire. Have the system checked promptly.
