Airbag control unit with part number 38910-80SC0

What does the airbag control unit 38910-80SC0 do?

For Suzuki, the airbag control unit 38910-80SC0 is the central control unit of the restraint system (SRS). It analyses the crash sensors, decides within milliseconds in a collision which airbags and seatbelt pretensioners to trigger, and monitors the system continuously.

The unit detects faults itself and shows them via the airbag warning light in the instrument cluster. The faults remain stored until they are read out.

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

Why does the control unit 38910-80SC0 fail?

Stored crash data is the most common cause in the 38910-80SC0, even if no airbag has deployed. Further causes are related to the electronics.

Crash data stays in the unit after an accident, and a normal diagnostic tool cannot delete it. Airbag24 erases it during the repair.

Other causes include ageing electronic components, cold solder joints, and moisture or corrosion at plug connections. Voltage spikes, for example from a weak battery, can also affect the control unit.

How can you tell that the 38910-80SC0 is defective?

A defect in the 38910-80SC0 shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Fault messages also appear, the diagnostic tool cannot establish a connection, and the fault memory cannot be cleared.

• Airbag warning light is on permanently or intermittently
• Fault message in the instrument cluster
• No connection between diagnostic tool and control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. The warning light reports the defect, so please take it seriously.
