Airbag control unit with part number 77960-TR0-P622-M1

What does the airbag control unit 77960-TR0-P622-M1 do?

As the central control unit of the restraint system (SRS) for Honda, the airbag control unit 77960-TR0-P622-M1 evaluates the crash sensors. In an accident it decides within milliseconds which airbags and seatbelt pretensioners are triggered.

In addition, it monitors the system continuously and reports faults via the airbag warning light.

After an accident the unit stores crash data and locks itself.

Why does the control unit 77960-TR0-P622-M1 fail?

Most often the cause is crash data stored from an accident, even when no airbag was triggered. Aged components, cold solder joints, moisture at plug connections and voltage spikes are also possible causes.

Crash data cannot be erased with a normal diagnostic tool. Airbag24 erases it during the repair.

Further causes at a glance:

• Ageing of the electronic components
• Cold solder joints on the circuit board
• Moisture and corrosion at plug connections
• Voltage spikes from a weak battery or jump-starting

How can you tell that the 77960-TR0-P622-M1 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. In addition there may be an error message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

If one of these findings is present, airbags and seatbelt pretensioners may not trigger in an emergency. The warning light is therefore a signal for a prompt check.
