Airbag control unit with part number 77960-TF0-G832-M3

What does the airbag control unit 77960-TF0-G832-M3 do?

Within the restraint system (SRS) of Honda, the airbag control unit 77960-TF0-G832-M3 takes over central control. It receives the signals from the crash sensors, determines within milliseconds in a crash which airbags and seatbelt pretensioners are triggered, and checks the system continuously.

It reports faults via the airbag warning light in the instrument cluster, so that you notice the fault straight away.

After an accident, the unit is locked once it has stored crash data.

Why does the control unit 77960-TF0-G832-M3 fail?

Crash data from an accident remains stored in the unit, even if no airbag has been triggered, and is the most common cause. It cannot be erased with a normal diagnostic tool. Other causes are ageing components, cold solder joints, moisture and corrosion, and voltage spikes.

The data is recorded during the accident and remains stored until the repair removes it.

Ageing components and cold solder joints can only be narrowed down by a precise inspection.

Moisture and corrosion disrupt signal transmission. Voltage spikes, for example from a weak battery or jump-starting, put additional strain on the electronics.

How can you tell that the 77960-TF0-G832-M3 is defective?

A defect is recognised by an airbag warning light in the instrument cluster that stays on permanently or intermittently, a message, a diagnostic tool without connection, and a fault memory that cannot be cleared. In this case, the airbags and seatbelt pretensioners may fail to trigger in an emergency.

• airbag warning light stays on permanently or intermittently
• message in the instrument cluster
• diagnostic tool does not connect to the control unit
• fault memory cannot be cleared

The light is a clear indication that the system has detected the defect. A prompt check is then advisable.

• Honda Jazz GE (2008-2015)

Comparing the part number on the label of the removed unit with this page only confirms that it is the right unit. Only reading out the fault memory shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 5WK43461, 77960-SAA-G821-M1, 77960-SEG-G821-M1, 77960-TF0-G820-M3, 77960-TF0-G821.

How does the repair of the 77960-TF0-G832-M3 work?

Have the fault memory read out and enclose the log, then disconnect the battery. Only afterwards remove the control unit, create a repair order online and then send in the unit, well packed. At Airbag24, processing usually takes 3–4 working days.

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

How does the control unit 77960-TF0-G832-M3 get to Airbag24?

The unit goes to Airbag24 as a parcel, or you can book a UPS collection for an extra charge. Returns after the repair are made by UPS.

Pack the control unit shock-proof and enclose the printed repair order.
