Airbag control unit with part number 38910-52RA0

What does the airbag control unit 38910-52RA0 do?

The 38910-52RA0 is the airbag control unit that coordinates the triggering of airbags and seatbelt pretensioners in Suzuki. It evaluates the crash sensors and determines in an accident, within milliseconds, which components become active.

At the same time it monitors the system continuously and reports faults via the airbag warning light.

After an accident it stores crash data and is locked afterwards.

Why does the control unit 38910-52RA0 fail?

The control unit 38910-52RA0 most often fails because of stored crash data, which remains in memory even after an accident without airbag triggering. Other causes include aged components, cold solder joints, moisture and corrosion at plug connections, as well as voltage spikes.

A normal diagnostic tool cannot erase the crash data. During repair at Airbag24 it is removed.

Aged components and cold solder joints impair the electronics. Moisture and corrosion attack the plug connections.

Voltage spikes arise, for example, from a weak battery or from jump-starting.

How can you tell that the 38910-52RA0 is defective?

A defect in the 38910-52RA0 is recognised by the airbag warning light in the instrument cluster, which lights up permanently or intermittently, by fault messages in the instrument cluster, by no connection to the diagnostic tool, and by a fault memory that cannot be cleared.

Such a finding means that airbags and seatbelt pretensioners may not deploy in an emergency. The signs show that there is a defect, but they do not show where it lies.

Which vehicles is the 38910-52RA0 fitted in?

Compare the sticker on the removed unit with this page. That only clarifies whether you have the matching unit. Whether the control unit is defective or a plug or cable is the cause is shown only by reading out the fault memory, which should be done in advance.

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

How does the repair of the 38910-52RA0 work?

First have the fault memory read out and attach the log, then disconnect the battery. Only then remove the control unit 38910-52RA0 and create a repair order online.

Pack the unit well and send it in.

Airbag24 checks the unit on the test bench, replaces defective components, erases the crash data and carries out a function test. Processing there usually takes 3–4 working days. 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.

How does the control unit 38910-52RA0 get to Airbag24?

You send the control unit 38910-52RA0 in as a parcel or have it collected by UPS for an extra charge. After repair, Airbag24 returns it by UPS.

Put the printed repair order into the parcel. Pack the unit shock-resistant.
