Airbag control unit with part number 77960-TG7-X210-M2

What does the airbag control unit 77960-TG7-X210-M2 do?

The airbag control unit 77960-TG7-X210-M2 is the central control unit of the restraint system (SRS) for Honda. It evaluates the signals from the crash sensors, decides in an emergency which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

The triggering decision is made in fractions of a second. The unit reports faults via the airbag warning light in the instrument cluster.

After an accident, it stores crash data and then locks itself.

Why does the control unit 77960-TG7-X210-M2 fail?

The most common cause with the 77960-TG7-X210-M2 is crash data stored after an accident, even if no airbag has triggered. Besides this, ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes come into play.

Crash data cannot be erased with an ordinary diagnostic tool. Airbag24 removes it in the course of the repair.

• ageing electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

Which cause applies in an individual case is shown by the evaluation of the fault memory.

How can you tell that the 77960-TG7-X210-M2 is defective?

A fault in the 77960-TG7-X210-M2 first becomes noticeable through the airbag warning light in the instrument cluster, which stays on permanently or intermittently. Added to this are an error message in the instrument cluster, a missing connection to the diagnostic tool, and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then possibly not trigger. The warning light is therefore not a minor matter but calls for action.

The light is the first sign you can observe. Pay particular attention to these indications:

• Airbag warning light in the instrument cluster
• Error message in the instrument cluster
• Diagnostic tool does not reach the control unit
• Fault memory cannot be cleared

Which vehicles is the 77960-TG7-X210-M2 fitted in?

The control unit 77960-TG7-X210-M2 is fitted in these vehicles: Honda Pilot 3rd generation (2015-2018) and 3rd generation Facelift (2018-2022).

The following overview shows which vehicles are assigned to this part number.

• Honda Pilot 3rd generation (2015-2018)
• Honda Pilot 3rd generation Facelift (2018-2022)

First compare the part number on the label of the removed unit with this page. This only confirms that you have the correct unit in front of you. Also have the fault memory read out beforehand, because this result shows whether the control unit is faulty or whether a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 77960-S9V-A013-C1, 77960-T90-A010-M1, 77960-T90-A011-M1.

How does the repair of the 77960-TG7-X210-M2 work?

First you have the fault memory read out and enclose the log. Then you disconnect the battery and only afterwards remove the control unit 77960-TG7-X210-M2.

Afterwards, you create a repair order online and send the unit in well packed. Airbag24 examines it on the test bench, repairs defective components, erases the crash data and carries out a function test, after which your own unit returns to you.

Processing at Airbag24 normally takes 3–4 working days. 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-TG7-X210-M2 get to Airbag24?

You bring the control unit 77960-TG7-X210-M2 to Airbag24 as a parcel, or you book a UPS collection for an extra charge. After the repair, it comes back to you by UPS.
