Airbag control unit with part number 38910-62H20

What does the airbag control unit 38910-62H20 do?

The airbag control unit 38910-62H20 belongs to the restraint system of Suzuki. It processes the signals from the crash sensors, decides in an accident on the triggering of airbags and seatbelt pretensioners, and monitors the entire system. After an accident it stores crash data and locks itself.

Monitoring runs without interruption during operation and covers sensors, wiring and the activation of the trigger units.

If the control unit detects a fault, it reports it via the airbag warning light. A warning signal therefore has a clear function.

Why does the control unit 38910-62H20 fail?

The most common cause on the 38910-62H20 is stored crash data after an accident, even if no airbag has triggered; a normal diagnostic tool cannot delete them. Further causes include ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Experts examine this point first when investigating, because it concerns the unit's memory.

Ageing electronics and cold solder joints are hard to see from outside. Moisture and corrosion, by contrast, attack the contacts, while voltage spikes can occur, for example with a weak battery or a jump start.

How can you tell that the 38910-62H20 is defective?

A defect shows itself through the airbag warning light in the instrument cluster, which lights up permanently or intermittently, and through a fault message in the instrument cluster. If the control unit cannot be reached by the diagnostic tool, or the fault memory cannot be cleared, that also points to a fault. Then the airbags and seatbelt pretensioners may not trigger in an emergency.

These indications help in recognising it:

• Airbag warning light lights up permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool does not reach the control unit
• Fault memory cannot be cleared

Which part is affected remains open with a warning light. That is what the fault memory readout is for.

Which vehicles is the 38910-62H20 fitted in?

The control unit 38910-62H20 is fitted in these vehicles: Suzuki Every DA52V and DA62V. The information serves to compare with your own vehicle.

The vehicles from the assignment follow here:

• Suzuki Every DA52V
• Suzuki Every DA62V

Comparing the part number on the label confirms only that it is the correct unit. Have the fault memory read out before removal; only the log shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 38910-68H00, 38910-84G10, 38910-84G11, 5WK43752.

How does the repair of the 38910-62H20 work?

First have the fault memory read out and attach the log to the order. Only then disconnect the battery and remove the control unit 38910-62H20. Processing at Airbag24 takes 3–4 working days as a rule.

Afterwards you create a repair order online and send in the unit well packed. Airbag24 checks it on the test bench, repairs defective components, deletes stored crash data and carries out a function test.

Then your own unit comes back to you. The time limit applies only to the work done in-house.

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 38910-62H20 get to Airbag24?

Either you send the control unit 38910-62H20 as a parcel, or you book a UPS collection for an extra charge. After the repair UPS delivers it back to you.

Print the repair order and put it into the parcel; in addition, shock-proof packaging is needed.
