Airbag control unit with part number 38910-62J01

What does the airbag control unit 38910-62J01 do?

The airbag control unit 38910-62J01 is the central control unit of the restraint system (SRS) for Suzuki. It evaluates the crash sensors, decides within milliseconds which airbags and seatbelt pretensioners are triggered in an accident, and monitors the entire system. It shows faults via the airbag warning light.

In addition, the manufacturer number Continental 5WK43538 is printed on the housing.

The connections to the sensors, the airbags and the seatbelt pretensioners are monitored constantly during operation. After an accident it stores crash data and is locked afterwards.

Why does the control unit 38910-62J01 fail?

The most common cause on the 38910-62J01 is crash data stored after an accident, even if no airbag deployed. A normal diagnostic tool cannot erase it; during the repair, Airbag24 takes care of this. Ageing, moisture and voltage spikes also play a role.

Electronic components age over their service life. Solder joints can also loosen over time and cause contact problems.

Moisture and corrosion affect the contacts at plug connectors. This disturbs the signal transmission between the unit and the sensors.

Voltage spikes occur, for example, when the battery is weak or a jump start is connected. Such loads act on the electronics.

How can you tell that the 38910-62J01 is defective?

On the 38910-62J01, you can recognise a fault by the airbag warning light, a fault message in the instrument cluster or a missing connection to the diagnostic tool. A fault memory that cannot be cleared is also a sign of this.

• Warning light on, permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be cleared

The light indicates the fault as soon as the system detects it. If it stays on, a closer check is needed.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The label comparison confirms that the removed unit matches this page. It says nothing more, so the cause is not established by it. Before removal, therefore, have the fault memory read out. Only the result shows whether the control unit is defective or whether a connector or a cable is the cause.

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 38910-62J01 work?

First you have the fault memory read out and attach the log to the unit. Then you disconnect the battery and only afterwards remove the control unit 38910-62J01. Online, you create the repair order, then you send in the well-packed unit.

Airbag24 examines the unit on the test bench and replaces defective components. Afterwards, Airbag24 deletes stored crash data and carries out a function test. The work at Airbag24, meaning checking, repairing and testing, usually takes 3–4 working days.

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. Your unit is then returned to you.

How does the control unit 38910-62J01 get to Airbag24?

You send the control unit 38910-62J01 as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 returns it by UPS. Please include the printed repair order with the parcel.
