Airbag control unit with part number 77960-SZA-A012-M1

What does the airbag control unit 77960-SZA-A012-M1 do?

The airbag control unit 77960-SZA-A012-M1 is the central control unit of the restraint system (SRS) for Honda. It processes the signals from the crash sensors, decides in an emergency within a few milliseconds on the triggering of the airbags and seatbelt pretensioners, and monitors the system continuously.

The unit reports faults via the airbag warning light in the instrument cluster. After an accident it stores crash data and locks itself.

Without working electronics, the restraint system cannot fulfil its task. The control unit therefore works closely with sensors and triggering circuits.

Why does the control unit 77960-SZA-A012-M1 fail?

For the control unit 77960-SZA-A012-M1, the most common cause after an accident is stored crash data, even if no airbag has been triggered. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

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

The other causes act over a longer period. Solder joints, plug connections and electronics react sensitively to moisture, ageing and sudden voltage spikes, for example after a jump start.

How can you tell that the 77960-SZA-A012-M1 is defective?

A defect on the control unit 77960-SZA-A012-M1 can be recognised by several signs that show up in the vehicle and on the diagnostic tool. In an emergency, airbags and seatbelt pretensioners may then possibly not trigger.

These signs occur:

• The airbag warning light lights up permanently or intermittently.
• The instrument cluster shows an error message.
• The diagnostic tool receives no connection to the control unit.
• The fault memory cannot be cleared.

Report such a finding promptly to a workshop, or have it read out.

Comparing the part number on the label of the removed unit with this page only confirms that you have the right unit. Having the fault memory read out, on the other hand, shows whether the control unit is defective or whether a plug or cable is the cause. So have the fault memory read out beforehand.

How does the repair of the 77960-SZA-A012-M1 work?

The fault memory is read out first, and the log is attached. Then you disconnect the battery and remove the control unit 77960-SZA-A012-M1. Online you create a repair order and send the unit in; at Airbag24 processing usually takes 3–4 working days.

Airbag24 checks the unit on the test bench, replaces defective components, erases stored crash data and carries out a function test.

Afterwards the 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-SZA-A012-M1 get to Airbag24?
