Airbag control unit with part number 77960-TR0-F613-M1

What does the airbag control unit 77960-TR0-F613-M1 do?

The airbag control unit 77960-TR0-F613-M1 is the central control unit of the SRS restraint system for Honda. It evaluates the signals from the crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident, it stores crash data and locks itself.

The unit reports faults via the airbag warning light in the instrument cluster. This is how you as the driver learn whether the restraint system is ready for everyday use.

The control unit thus acts as the switching point between the sensors and the triggering units. If something conspicuous occurs there, the fault is first visible at this point in the system.

Why does the control unit 77960-TR0-F613-M1 fail?

With the 77960-TR0-F613-M1, the most common cause is stored crash data from an accident, even if no airbag was triggered. Aged components, moisture at plug connections and voltage spikes are also possible causes.

A normal diagnostic tool cannot erase this crash data. Airbag24 erases it during the repair.

Further causes include:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump starting

How can you tell that the 77960-TR0-F613-M1 is defective?

A defect in the 77960-TR0-F613-M1 shows up as the airbag warning light in the instrument cluster lighting up permanently or intermittently. In addition there may be an error message in the instrument cluster, no contact between the diagnostic tool and the control unit, and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy. A lit warning light is therefore a clear reason to have the condition checked.

Even if the light goes out at times, the message is not resolved. The fault memory shows what the system has detected.

Two checks help before removal. Comparing the part number on the label of the removed unit with this page only confirms that you have the right unit. Also have the fault memory read out beforehand, because only this result shows whether the control unit is defective or whether a plug or cable is the cause.
