Airbag control unit with part number 38910-58M00

What does the airbag control unit 38910-58M00 do?

The airbag control unit 38910-58M00 evaluates the crash sensors of the restraint system (SRS) in the Suzuki. In an accident it decides within milliseconds which airbags and seatbelt pretensioners fire.

During operation it monitors all components of the system for irregularities. A detected fault is reported via the airbag warning light in the instrument cluster and stored in the fault memory.

After an accident the unit secures the crash data and then locks itself. Its function is therefore of central importance for the safety of the occupants.

Why does the control unit 38910-58M00 fail?

The most common cause is crash data that remains stored in the unit after an accident, even without a deployed airbag. Aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are further possible causes.

Crash data cannot be erased with an ordinary diagnostic tool. It therefore stays in the unit, and Airbag24 erases it during the repair.

The other causes result from ageing and environmental influences. Electronics become more susceptible over time, solder joints can become brittle, and moisture leads to corrosion on contacts. Voltage spikes additionally strain the circuit, for example with a weak battery or a jump start.

How can you tell that the 38910-58M00 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently as soon as the 38910-58M00 has a defect. Matching this are a fault message in the instrument cluster, a lost connection to the diagnostic tool and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. You should therefore not ignore this warning.

If such signs appear, have the system checked, even if the vehicle seems unremarkable in everyday use. The warning light serves exactly this purpose.

Compare the part number on the label of the removed unit with this page. A comparison only confirms that it is the right unit. Only the fault memory shows whether the control unit itself is defective or whether a plug or cable is the cause, so have it read out beforehand.

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

How does the repair of the 38910-58M00 work?

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

Airbag24 checks the unit on the test bench, repairs defective components, erases the stored crash data and carries out a function test. Afterwards the unit goes back to you.

The processing takes 3–4 working days and concerns only checking, repairing and testing. 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 38910-58M00 get to Airbag24?

You can send the control unit 38910-58M00 yourself as a parcel or book a UPS collection for an extra charge. The return after the repair is made by UPS.

A shockproof packed unit with the printed repair order in the parcel is the safe way.
