Airbag control unit with part number 77960-SNB-T013-M1

What does the airbag control unit 77960-SNB-T013-M1 do?

The airbag control unit 77960-SNB-T013-M1 is the central control unit of the restraint system for Honda. It processes the signals from the crash sensors and decides in an accident on the triggering of airbags and seatbelt pretensioners. At the same time it monitors the system continuously and reports faults via the airbag warning light.

The crash sensors supply measurements continuously, from which the unit derives its decision. This evaluation runs without a break.

After an accident the unit stores crash data and locks itself. A reported fault therefore requires prompt checking.

Why does the control unit 77960-SNB-T013-M1 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a standard diagnostic tool cannot erase it. Further causes are ageing components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data remain in the unit even if no airbag and no seatbelt pretensioner fired in the accident. A standard diagnostic tool cannot be made to remove them, and that is exactly what keeps the fault memory occupied.

Electronics age, and solder joints can go cold over time. Moisture and corrosion at plug connections disrupt the contact, and voltage spikes in the vehicle electrical system, for example from a weak battery or a jump-start, place extra strain on the electronics. The check establishes which cause applies.

How can you tell that the 77960-SNB-T013-M1 is defective?

A defect on the 77960-SNB-T013-M1 is indicated by the airbag warning light in the instrument cluster staying on permanently or intermittently. Added to this are an error message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

Typical signs are:

• Airbag warning light permanently or intermittently on
• Error message in the instrument cluster
• Diagnostic tool does not find the control unit
• Fault memory cannot be cleared

With these signs, airbags and seatbelt pretensioners may fail to deploy in an emergency. The warning light shows the finding, regardless of how the vehicle behaves in everyday use.

Compare the part number on the label of the removed unit with this page, because that only ensures that it is the right unit. Have the fault memory read out beforehand, because only the log shows whether the control unit itself is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 77960-S02-A840-M3, 77960-SMG-G014-M1.

How does the repair of the 77960-SNB-T013-M1 work?

For the 77960-SNB-T013-M1, first have the fault memory read out and enclose the log. Then disconnect the battery and only then remove the control unit. Then create a repair order online and send in the unit, well packed. Airbag24 needs 3–4 working days for checking, repairing and the function test.

Airbag24 checks the unit on the test bench, repairs defective components, erases stored crash data and carries out a function test. Afterwards your own unit goes back to you.

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.

How does the control unit 77960-SNB-T013-M1 get to Airbag24?

You send the control unit 77960-SNB-T013-M1 in as a parcel or book a UPS collection for an extra charge. After the repair Airbag24 sends it back by UPS.

Enclose the printed repair order in the parcel and pack the unit shockproof.
