Airbag control unit with part number 77960-TS8-3060-M4

What does the airbag control unit 77960-TS8-3060-M4 do?

The airbag control unit 77960-TS8-3060-M4 forms the central control of the restraint system (SRS) for Honda. It processes the signals from the crash sensors, triggers the appropriate airbags and seatbelt pretensioners within milliseconds in a crash, and monitors the system continuously. It shows faults via the airbag warning light.

The analysis runs continuously in the background. If the control unit detects a fault, it stores it in the fault memory.

A crash causes the control unit to store crash data and then lock itself.

Why does the control unit 77960-TS8-3060-M4 fail?

Crash data stored after an accident is the most common cause, even when no airbag has deployed. Aged components, cold solder joints, moisture and corrosion at plug connectors, as well as voltage spikes can also lead to failure.

Such crash data cannot be removed with a usual diagnostic tool. Airbag24 erases it during the repair.

The other causes concern the electronics themselves. Components age, solder joints can go cold, and moisture or corrosion attack the plug connectors. Voltage spikes, for example from a weak battery or jump-starting, put additional strain on the unit.

How can you tell that the 77960-TS8-3060-M4 is defective?

A defect shows itself through the airbag warning light in the instrument cluster staying on permanently or intermittently, through a fault message in the instrument cluster, and through a missing connection to the diagnostic tool. If the fault memory also cannot be cleared, that is another sign. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

Signs include:

• the airbag warning light in the instrument cluster stays on permanently or intermittently
• a fault message appears in the instrument cluster
• the diagnostic tool gets no connection to the control unit
• the fault memory cannot be cleared

The warning light makes the defect visible to you. So have the restraint system checked promptly.

Both things are important when removing the unit, and you can take care of them yourself. Compare the part number on the label of the removed unit with this page, so you are sure it is the right unit. Then have the fault memory read out, because only this log shows whether the control unit is defective or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 77960-TS4-U411-M1, 77960-TS4-U811-M2, 77960-TS4-Z611-M1, 77960-TS6-H711-M1, 77960-TT0-T011-M1, 77960-TT0-Y610-M2.

How does the repair of the 77960-TS8-3060-M4 work?

First have the fault memory read out and the log enclosed, then disconnect the battery and remove the control unit. Then create a repair order online and send in the well-packed unit. Processing at Airbag24 usually takes 3–4 working days.

Airbag24 tests the unit on the test bench, replaces defective components, erases stored crash data and carries out a function test. After that you get your own unit back.

The sequence on the vehicle is fixed: the control unit may only be removed once the battery has been disconnected.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
