Airbag control unit with part number 38910-80SA0

What does the airbag control unit 38910-80SA0 do?

The airbag control unit 38910-80SA0 coordinates the SRS restraint system of Suzuki. From the readings of the crash sensors it works out within milliseconds whether a crash requires deployment, and then triggers the appropriate airbags and seatbelt pretensioners.

During operation the unit monitors the system continuously. Any faults are passed on via the airbag warning light in the instrument cluster.

After a crash it stores crash data and locks itself. The lock is only lifted by the repair.

Why does the control unit 38910-80SA0 fail?

The most common cause is stored crash data from an earlier accident, even if no airbag was deployed. An ordinary diagnostic tool does not erase it. Aged components, cold solder joints and corrosion at plug connections are also possible causes.

• 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 causes applies to your unit cannot be read from the part number. Only evaluating the fault memory shows that.

How can you tell that the 38910-80SA0 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 then finds no connection to the control unit, and the fault memory cannot be cleared.

If the light indicates a fault, airbags and seatbelt pretensioners may not deploy in an emergency.

Such messages do not always concern the control unit itself. That is why only the fault memory provides clarity.

The most reliable way to check whether the unit fits your car is by the number on the label of the removed control unit. Comparing it with this page only confirms that it is the right unit. Before that, have the fault memory read out, because only the result shows whether the control unit is defective or a plug or cable is the cause.
