Airbag control unit with part number 38910-81P00

What does the airbag control unit 38910-81P00 do?

The airbag control unit 38910-81P00 controls the restraint system (SRS) in the Suzuki and is responsible for triggering airbags and seatbelt pretensioners. It continuously checks via the crash sensors whether an accident has occurred and decides on triggering within a few milliseconds in an emergency. At the same time it checks the system and shows faults via the airbag warning light.

After an accident the unit stores crash data and locks itself. This property is built into the control unit and is part of the safety concept of the system.

The evaluation of the sensor signals takes place entirely inside the unit and not in the airbag itself. That is why the control unit is the point to raise during a diagnosis.

Why does the control unit 38910-81P00 fail?

On the 38910-81P00, stored crash data after an accident is the most common cause, even if no airbag has deployed. A normal diagnostic tool cannot erase this data. Other causes include aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

Even without an airbag triggering, the unit can record data. Whether such entries exist is shown only by reading out the unit itself.

The other causes develop over a longer period and are hard to classify without testing. Airbag24 removes the crash data during repair.

How can you tell that the 38910-81P00 is defective?

A defect on the 38910-81P00 shows itself mainly at the airbag warning light in the instrument cluster and in further signs that you notice in the vehicle. If you notice these signs, have the system checked promptly.

• Airbag warning light in the instrument cluster lights up permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool gets no connection to the control unit
• Fault memory cannot be cleared

In this case, airbags and seatbelt pretensioners could possibly fail to deploy in a crash. The warning light indicates the defect and is therefore the most important warning signal.

Compare the part number on the label with this page. That only ensures that you have the right unit in front of you. Have the fault memory read out beforehand, because only this result shows whether the control unit itself is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 38910-81P61, XC2336B-40F.

How does the repair of the 38910-81P00 work?

First have the fault memory read out and attach the log. Then disconnect the battery, only then remove the 38910-81P00 and create a repair order online before sending in the unit well packed.

On the test bench, Airbag24 examines the unit, replaces defective components, erases stored crash data and carries out a function test. Usually 3–4 working days are planned for this work.

Afterwards your own 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.
