Airbag control unit with part number 38910-68L01

What does the airbag control unit 38910-68L01 do?

It controls the SRS system of Suzuki as the central unit. The sensor signals converge here and are evaluated within milliseconds, after which the decision is made as to which airbags and seatbelt pretensioners trigger. The unit monitors the system constantly and reports faults via the airbag warning light.

The evaluation of the crash sensors runs continuously and not only in an accident. To do this, the control compares the measured values with the specifications all the time.

Once a crash has occurred, the unit stores the crash data and locks itself.

Why does the control unit 38910-68L01 fail?

Stored crash data is the most common cause, and this applies even when no airbag was triggered in the accident. A normal diagnostic tool cannot erase it; Airbag24 handles that during the repair. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting, also play a role.

Stored crash data shows an event. It is not proof of a defect in the unit.

The other causes arise over time or under environmental influences. Ageing, moisture and corrosion attack contacts, while voltage fluctuations stress components.

How can you tell that the 38910-68L01 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, a fault message appears in the instrument cluster, or the fault memory cannot be cleared. A diagnostic tool that cannot make contact with the control unit is a further sign.

You must take these signs seriously. In an emergency, airbags and seatbelt pretensioners may fail to trigger, so do not wait, but have the system checked.

Compare the part number on the label of the removed unit with this page; then you know that you have the right unit in front of you. Also have the fault memory read out before you remove the unit. Only it 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 38910-52R00, 38910-52RA0, 38910-52RC0, 38910-52RC1, 38910-52RC2, 38910-52RE0.

How does the repair of the 38910-68L01 work?

First read out the fault memory and enclose the log, then disconnect the battery and only then remove the unit. Airbag24 needs 3–4 working days for checking, repairing and testing.

After that you create a repair order online and send in the well-packed unit. At Airbag24 the unit is checked on the test bench, defective components are repaired, stored crash data is erased and a function test is carried out. Afterwards your own, repaired unit is sent 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 38910-68L01 get to Airbag24?

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