Airbag control unit with part number 38910-62J20-000

What does the airbag control unit 38910-62J20-000 do?

The central control unit of the restraint system of Suzuki is the airbag control unit 38910-62J20-000. It evaluates the crash sensors, determines in an accident which airbags and seatbelt pretensioners are triggered, and continuously checks the entire system. It indicates faults via the airbag warning light.

The decision is made within milliseconds as soon as the sensors detect the accident.

After an accident, it stores crash data and locks itself.

Why does the control unit 38910-62J20-000 fail?

The most common cause is stored crash data after an accident, even without a triggered airbag, and a standard diagnostic tool cannot erase it. In addition come aging of the electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

The causes in detail:

• Crash data from an accident, even without a triggered airbag
• Aged electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or jump-starting

Which of these applies to a particular device only becomes clear after the check.

How can you tell that the 38910-62J20-000 is defective?

A defect shows up as the airbag warning light, which lights up permanently or intermittently, as an error message in the instrument cluster, as the diagnostic tool having no connection, and as a fault memory that cannot be erased.

Identifying features:

• Airbag warning light in the instrument cluster
• Error message in the instrument cluster
• Diagnostic tool cannot reach the control unit
• Fault memory cannot be erased

In an emergency, airbags and seatbelt pretensioners may not be able to deploy. The warning should therefore be taken seriously.

Comparing the part number on the label of the removed device with this page confirms that you have the right device. To clarify the cause, however, the fault memory must be read out, because it shows whether the control unit or a plug or cable is affected.

For the same vehicles, we also repair control units with the part numbers 38910-52R00, 38910-52RA0, 38910-52RC0, 38910-52RC1, 38910-52RC2, 38910-52RE0.

How does the repair of the 38910-62J20-000 work?

First have the fault memory read out and attach the log. In the next step, disconnect the battery, then remove the control unit and create the repair order online.

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

Afterwards, you receive your device 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 38910-62J20-000 get to Airbag24?

You send the control unit off as a parcel or book a UPS collection for an extra charge. Airbag24 sends it back to you by UPS after the repair.

The printed repair order goes in the parcel, and the device is packed shock-proof.
