Airbag control unit with part number 77960-SHJ-Y017-M1

What does the airbag control unit 77960-SHJ-Y017-M1 do?

The control unit 77960-SHJ-Y017-M1 is the central airbag control unit for Honda and monitors the restraint system (SRS). It evaluates impact signals, decides when the airbags and seatbelt pretensioners fire, and after an accident stores crash data, after which it locks itself.

The evaluation takes only milliseconds, and the device checks the system for faults permanently. If it detects a fault, it reports it via the airbag warning light in the instrument cluster.

Why does the control unit 77960-SHJ-Y017-M1 fail?

The most common cause with 77960-SHJ-Y017-M1 is crash data from an accident, even when no airbag has triggered. Further triggers are aged components, cold solder joints, moisture and corrosion, and voltage spikes.

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

Aged electronics, cold solder joints and corrosion at plug connections change the behaviour of the circuit gradually. Voltage spikes, for example from a weak battery or a jump-start, can additionally stress components.

How can you tell that the 77960-SHJ-Y017-M1 is defective?

You recognise a defect in the 77960-SHJ-Y017-M1 by the airbag warning light, which lights up permanently or only intermittently. The instrument cluster also shows a fault message, and the diagnostic tool gets no connection to the control unit.

A fault memory that cannot be cleared is a further sign. In that case airbags and seatbelt pretensioners may fail to trigger in an emergency.

Compare the part number on the label of your removed unit with this page, and you will know that it is the right unit. Whether a defect is actually present or a plug or cable is the cause is shown only by the fault memory, which you should have read out beforehand.

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-SHJ-Y017-M1 work?

At Airbag24 checking, repairing and testing the 77960-SHJ-Y017-M1 usually take 3–4 working days. On the test bench Airbag24 replaces defective components, erases stored crash data and carries out a function test.

Your own steps are independent of this: have the fault memory read out and attach the log, then disconnect the battery and only afterwards remove the control unit. Then create a repair order online and send in the well-packed unit.

After the function test 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.
