Airbag control unit with part number 77960-SLE-H012-M3

What does the airbag control unit 77960-SLE-H012-M3 do?

The 77960-SLE-H012-M3 is the central control unit of the restraint system (SRS) of Honda. It evaluates the crash sensors, decides within milliseconds in a crash on airbags and seatbelt pretensioners, 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. The checks also run in the background while driving.

The crash data remain stored in the unit without you noticing anything in everyday driving.

Why does the control unit 77960-SLE-H012-M3 fail?

Crash data stored after an accident are the most common cause, even if no airbag has triggered. A normal diagnostic tool cannot erase them. Further causes are aged components, cold solder joints, corrosion at connectors and voltage spikes.

Aged components are part of any electronics that work in a vehicle for a long time. Cold solder joints are another known source of fault.

Corrosion and moisture at connectors disturb the contact. Voltage spikes arise, for example, from a weak battery or from a jump start and stress the electronics.

How can you tell that the 77960-SLE-H012-M3 is defective?

A defect shows up as the airbag warning light in the instrument cluster staying on permanently or intermittently, as an error message in the instrument cluster, as a diagnostic tool without connection to the control unit, or as a fault memory that cannot be cleared. Then the airbags and seatbelt pretensioners may possibly not trigger in an emergency.

The warning light is the most important indication this unit gives you. It comes on when you switch on, and if it stays on or flickers afterwards, the system has detected a fault.

A missing connection to the diagnostic tool does not necessarily lie in the control unit itself. Wiring and connectors also come into consideration, and the readout of the fault memory shows which part is affected.

First you can compare the part number on the label of the removed unit with this page. This only shows whether it is the right unit. In addition, have the fault memory read out, because only the report shows whether the control unit is defective or whether a connector or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 77960-SHJ-A013-M1, 77960-SHJA020M1, 77960-SHJC-012-M1, 77960-TK8-A011-M1.

How does the repair of the 77960-SLE-H012-M3 work?

You begin by reading out the fault memory and enclosing the report. Then you disconnect the battery, remove the control unit and create a repair order online. You then send the well-packed unit in.

The order is important for safety, because the control unit may only be removed after disconnecting.

At Airbag24 the team checks the unit, repairs defective components, erases stored crash data and carries out a functional test. Processing usually takes 3–4 working days. Afterwards your own unit is returned 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.
