Airbag control unit with part number 38910-79M10

What does the airbag control unit 38910-79M10 do?

The airbag control unit 38910-79M10 controls the restraint system (SRS) of Suzuki and is its central control unit. In an accident it evaluates the sensor signals and determines within milliseconds which airbags and seatbelt pretensioners are triggered.

While driving, the control unit monitors the connected components continuously. It reports faults via the airbag warning light shown in the instrument cluster.

After an accident it stores crash data and locks itself. The entire restraint system depends on this unit working without faults.

Why does the control unit 38910-79M10 fail?

The most common cause of failure on the 38910-79M10 is stored crash data from an accident, even when no airbag was triggered. Other causes are aged components, cold solder joints, moisture and corrosion, and voltage spikes.

Crash data cannot be erased with a normal diagnostic tool. At Airbag24 it is erased as part of the repair.

The other causes include these points:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 38910-79M10 is defective?

A defect shows itself when the airbag warning light on the 38910-79M10 control unit in the instrument cluster lights up permanently or intermittently, when a fault message appears, or when the diagnostic tool cannot connect to the control unit. A fault memory that cannot be cleared also points to it.

Do not ignore the warning light, because in a real emergency the airbags and seatbelt pretensioners may fail to fire.

The warning light shows the defect. A check is therefore the next step.
