Airbag control unit with part number 38910-73SC0

What does the airbag control unit 38910-73SC0 do?

The airbag control unit 38910-73SC0 controls the restraint system (SRS) of Suzuki. It reads the crash sensors, evaluates an impact within milliseconds and then triggers the appropriate airbags and seatbelt pretensioners.

Between accidents, the unit continuously checks all components of the system. If it finds an irregularity, it stores the fault and reports it to the driver.

After an accident, the control unit stores crash data and then locks itself. That is precisely why it is the central component when failures occur.

Why does the control unit 38910-73SC0 fail?

By far the most common cause is crash data stored after an accident, even when no airbag has deployed, and a standard diagnostic tool cannot delete it. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes such as those from a weak battery or jump-starting are also involved.

Stored crash data can cause the unit to show a fault at every start, even though the electronics themselves are fine. Airbag24 deletes this data during the repair.

For the other causes, components age over time, solder joints can be cold from the factory, and plug connections suffer from moisture and corrosion. Voltage spikes from the vehicle electrical system take their toll as well.

How can you tell that the 38910-73SC0 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, a fault message appears in the instrument cluster, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

In such a case, airbags and seatbelt pretensioners may not deploy in an emergency. The warning light is therefore the most important warning and by no means a trivial matter.

Anyone who ignores the light for long wastes time when looking for the cause. A check of the system quickly establishes whether it still works fully.

Which vehicles is the 38910-73SC0 fitted in?

The 38910-73SC0 is fitted in these vehicles: Suzuki Ignis MF33S. Only the comparison with the label shows whether it matches your part number.

Here are the vehicles for this part number:

• Suzuki Ignis MF33S

Comparing the part number on the label with this page only confirms that the removed unit is the correct one. Before you send it in, have the fault memory read out as well, since only the log shows whether the control unit itself is defective or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 38910-62RE0.

How does the repair of the 38910-73SC0 work?

First have the fault memory read out and enclose the log. Then disconnect the battery and only afterwards remove the control unit. Next, create a repair order online and send the unit in, well packed.

Removal only begins once the fault memory is secured and the battery has been disconnected. The repair order is the route by which Airbag24 assigns your unit.

At Airbag24, testing, repairing and checking usually take 3–4 working days. The unit is checked on the test bench, defective components are repaired and the crash data is deleted. A function test concludes the work, and your own unit comes 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 38910-73SC0 get to Airbag24?

You can send the 38910-73SC0 to Airbag24 as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 returns the unit to you by UPS.

Put the printed repair order in the parcel, and pack the unit shock-proof.
