Airbag control unit with part number 38910-76R00

What does the airbag control unit 38910-76R00 do?

In the restraint system (SRS) of Suzuki, the airbag control unit 38910-76R00 decides whether airbags and seatbelt pretensioners are triggered. To do this, it evaluates the crash sensors within milliseconds of an impact. It also monitors the system continuously and shows faults via the airbag warning light.

After an accident, the unit stores crash data and locks itself.

Otherwise, the control unit runs unobtrusively; faults it detects are stored in the fault memory.

Why does the control unit 38910-76R00 fail?

With the 38910-76R00, stored crash data from an accident is most often to blame, even when no airbag has deployed; a standard diagnostic tool cannot erase it. Other causes include aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

Crash data remains in the unit until Airbag24 erases it during the repair.

Other possible causes are:

• aged components in the electronics
• cold solder joints
• moisture and corrosion at plug connectors
• voltage spikes, for example from a weak battery or jump-starting

You will see which cause applies after a fault readout.

How can you tell that the 38910-76R00 is defective?

A defect in the 38910-76R00 can be recognised by the airbag warning light in the instrument cluster, which lights up permanently or intermittently, and by an error message in the instrument cluster. In addition, the diagnostic tool cannot connect to the control unit, and the fault memory cannot be cleared. Airbags and seatbelt pretensioners may then possibly fail to deploy in an emergency.

The warning light is the clear sign that something is wrong in the restraint system. If it stays on permanently, have the system checked promptly by a specialist workshop.

An error message in the instrument cluster or a fault memory that cannot be cleared also calls for an inspection.
