Airbag control unit with part number 38910-76M00

What does the airbag control unit 38910-76M00 do?

The airbag control unit 38910-76M00 coordinates the restraint system (SRS) of Suzuki. It evaluates the data of the crash sensors, decides in an accident within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors the system without interruption.

The unit registers faults in the system and reports them via the airbag warning light. The light in the instrument cluster is therefore the first warning if something is wrong.

After an accident the unit stores crash data and locks itself. The lock is a feature of the control unit and has nothing to do with the external condition of the vehicle.

Why does the control unit 38910-76M00 fail?

The most common cause is stored crash data after an accident, even if no airbag has deployed, and these cannot be cleared with normal diagnostic equipment. Further causes are:

Besides the crash data, there are several reasons that relate to the age of the unit and its surroundings.

• aged electronic components whose behaviour has changed
• cold solder joints on the circuit board
• moisture and corrosion at the plug connections
• voltage spikes from a weak battery or a jump start

Which cause is present only becomes clear from the readout and the subsequent check. Until then, every assumption remains open.

How can you tell that the 38910-76M00 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, and a fault message appears in the instrument cluster. The diagnostic tool does not reach the control unit, or the fault memory remains despite an attempt to clear it.

The warning light is the most unambiguous sign. Do not ignore it, because it shows that the restraint system has detected a fault.

In an emergency, airbags and seatbelt pretensioners may not trigger once the control unit is defective. A prompt check is therefore the right step.

Compare the part number on the label of the removed control unit with this page. This confirms that you have the right unit. Have the fault memory read out beforehand, because only the log 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 38910-84MD0.

How does the repair of the 38910-76M00 work?

First have the fault memory read out and attach the log. Then disconnect the battery, and only after that remove the control unit. Next, create a repair order online and send the well-packed unit in.

Airbag24 checks the control unit on the test bench and repairs defective components. The stored crash data is then erased, and a functional test completes the work. Afterwards the unit goes back to you.

Processing at Airbag24 usually takes 3–4 working days, and only for checking, repairing and testing. 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 38910-76M00 get to Airbag24?

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

Put the printed repair order in the parcel and pack the control unit shock-proof, so that it survives transport intact.
