Airbag control unit with part number 38910-64R10

What does the airbag control unit 38910-64R10 do?

The airbag control unit 38910-64R10 is the control unit of the SRS restraint system in Suzuki. It evaluates crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners trigger, and monitors the system continuously. Faults are shown via the airbag warning light.

While driving, the unit continuously checks the system in the vehicle, i.e. sensors, cables and trigger elements. In doing so it stores every deviation it finds.

After an accident the unit stores crash data and locks itself.

Why does the control unit 38910-64R10 fail?

The most common cause is stored crash data that remain in the unit after an accident, even without an airbag deployment. A normal diagnostic tool cannot erase them. Ageing electronic components, cold solder joints, moisture and corrosion on plug connections and voltage spikes also play a role.

Crash data remain in the memory even when there is little to see on the vehicle. That makes them easy to overlook during fault finding.

Solder joints and plug connections are typical weak points where moisture and corrosion take hold. Ageing components lose reliability over the years.

Voltage spikes arise, among other things, from a weak battery or from jump-starting. Such fluctuations stress the electronics.

How can you tell that the 38910-64R10 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and the instrument cluster shows an error message. The diagnostic tool cannot establish a connection to the control unit, and the fault memory cannot be cleared. Airbags and seatbelt pretensioners may then not be able to trigger in an emergency.

• Airbag warning light stays on permanently
• Airbag warning light flashes or comes on intermittently
• Error message in the instrument cluster
• Diagnostic tool does not find the control unit
• Fault memory cannot be cleared

The warning light is the indication the vehicle gives itself. Take it seriously before the problem gets worse.

Comparing the part number on the label with this page confirms that you have the correct control unit, nothing more. Whether it is defective is shown by the fault memory, which you have read out beforehand. Only then do you know whether a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 38910-61M00, 38910-61M01, 38910-61M10, 38910-61M11, 38910-61M20, 38910-61M21.

How does the repair of the 38910-64R10 work?

Have the fault memory read out first and enclose the log. Then disconnect the battery and only afterwards remove the control unit. Next, create a repair order online and send in the well-packed unit. Processing at Airbag24, i.e. inspecting, repairing and testing, usually takes 3–4 working days.

The sequence is predetermined for your safety. The battery therefore stays disconnected before removal.

At Airbag24 the unit is inspected, defective components are repaired, stored crash data are erased and a function test is carried out. A function test follows before your own unit goes back.

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 38910-64R10 get to Airbag24?

You hand in the control unit as a parcel, or you book a UPS collection for an extra charge. Airbag24 also sends the unit back to you by UPS after the repair.

Put the printed repair order in the parcel and pack the control unit shockproof.
