Airbag control unit with part number 38910-68L00

What does the airbag control unit 38910-68L00 do?

The airbag control unit 38910-68L00 is the central control unit of the restraint system (SRS) of Suzuki. It evaluates crash sensors, decides in an accident within milliseconds whether to trigger airbags and seatbelt pretensioners, and monitors the system continuously. Disrupted functions are reported via the airbag warning light; after an accident it stores crash data and locks itself.

Evaluating the sensor signals is the actual task of the device. In addition, it continuously checks whether the connected components have a connection and work plausibly.

Monitoring runs in the background without any action by the driver.

Why does the control unit 38910-68L00 fail?

The most common cause is crash data stored after an accident, even if no airbag has triggered. Other possible causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Stored crash data remains in the device until it is removed, and an ordinary diagnostic tool cannot do that. Airbag24 deletes it during the repair.

Aged components become more sensitive over time. Cold solder joints, moisture and corrosion at plug connections disturb the signal path, and voltage spikes put additional stress on the components.

How can you tell that the 38910-68L00 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, an error message appears in the instrument cluster, the diagnostic tool cannot find the control unit, or the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then possibly not trigger.

These signs can be recognised on the vehicle itself:

• Airbag warning light on permanently or intermittently
• Error message in the instrument cluster
• No connection between the diagnostic tool and the control unit
• Fault memory cannot be cleared

Have it checked if the light stays on. The cause, however, only becomes clear when the fault memory is read out.

Which vehicles is the 38910-68L00 fitted in?

The control unit 38910-68L00 is fitted in these vehicles: Suzuki Swift RZ/AZ (2017-2020), MZ/EZ Facelift (2008-2010), EA (1989-1995), AA (1983-1989), FZ/NZ (2010-2013), MZ/EZ (2005-2008), RZ/AZ Facelift (2020-2024), FZ/NZ Facelift (2013-2017), YED (from 2024) and MA (1995-2003). A comparison with your vehicle is worthwhile before you remove the device.

The list shows the vehicle types stored for this number.

• Suzuki Swift RZ/AZ (2017-2020)
• Suzuki Swift MZ/EZ Facelift (2008-2010)
• Suzuki Swift EA (1989-1995)
• Suzuki Swift AA (1983-1989)
• Suzuki Swift FZ/NZ (2010-2013)
• Suzuki Swift MZ/EZ (2005-2008)
• Suzuki Swift RZ/AZ Facelift (2020-2024)
• Suzuki Swift FZ/NZ Facelift (2013-2017)
• Suzuki Swift YED (from 2024)
• Suzuki Swift MA (1995-2003)

Comparing the label on the removed device confirms that you have the right device. The fault memory, on the other hand, indicates whether the control unit is defective or whether a plug or cable is the cause. Therefore have it read out beforehand.

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 38910-68L00 work?

Read out the fault memory first, then disconnect the battery and only then remove the control unit. Afterwards, create the repair order online and send the device in well packed. Processing at Airbag24 usually takes 3–4 working days.

The sequence is mandatory for safety reasons. You enclose the protocol of the fault memory with the parcel.

Airbag24 checks the device on the test bench, repairs defective components, deletes stored crash data and carries out a function test. Afterwards your own device 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 38910-68L00 get to Airbag24?

You send the device as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 sends the control unit back by UPS.

Enclose the printed repair order in the parcel, and pack the control unit shockproof.
