Airbag control unit with part number 38910-80S00

What does the airbag control unit 38910-80S00 do?

The unit is responsible for the restraint system of Suzuki. It checks the crash sensors, decides in an impact which airbags and seatbelt pretensioners are triggered, and monitors the entire system. After an accident, it stores crash data and locks itself.

The control unit works constantly in the background and reports faults via the airbag warning light in the instrument cluster. In this way the driver recognises that something is wrong with the restraint system.

In an emergency, the evaluation has to happen in fractions of a second. The control unit is designed for this.

Why does the control unit 38910-80S00 fail?

Most often the cause lies in the crash data stored after an accident, even if no airbag has deployed, and which cannot be erased from the 38910-80S00 with a normal diagnostic tool. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are also involved.

The crash data are stored measurements from the accident. They remain in the unit until Airbag24 removes them during the repair.

The other causes originate in the electronics or the plugs. Cold-soldered joints, moisture in the contacts and corrosion impair the connection. Voltage spikes, for example from a weak battery or when connecting a jump start, can also lead to faults.

How can you tell that the 38910-80S00 is defective?

The airbag warning light in the instrument cluster lights up constantly or intermittently, fault messages appear in the instrument cluster, the diagnostic tool finds no connection on the 38910-80S00, and the fault memory cannot be cleared. Airbags and seatbelt pretensioners may then fail to deploy in an emergency.

Take these signs seriously and have them checked:

• airbag warning light on constantly or intermittently
• fault message in the instrument cluster
• no connection of the diagnostic tool to the control unit
• fault memory cannot be cleared

Which vehicles is the 38910-80S00 fitted in?

Carry out the label comparison with the part number on the removed unit. It confirms that this is the correct unit, but says nothing about a defect. Have the fault memory read out beforehand, because only the log shows whether the control unit itself or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 38910-62J12-000, 38SC001R9RH.

How does the repair of the 38910-80S00 work?

First have the fault memory read out and attach the log. Then disconnect the battery and only then remove the 38910-80S00. Next, create a repair order online and pack the unit well before sending it in. Processing at Airbag24 usually takes 3–4 working days.

The removal takes place only once the battery has been disconnected. This serves safety around the airbag system.

At Airbag24 the unit is inspected on the test bench, defective components are replaced, the stored crash data is removed and a function test follows. The unit of your own is then 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 38910-80S00 get to Airbag24?

You send the 38910-80S00 as a parcel, or you book UPS collection for an extra charge. The return after the repair is made by UPS.

Enclose the printed repair order with the parcel. Pack the unit shockproof.
