Airbag control unit with part number 38910-73S00

What does the airbag control unit 38910-73S00 do?

The airbag control unit 38910-73S00 is the central control unit of the restraint system (SRS) for Suzuki. It evaluates the signals from the crash sensors and decides in an accident, within milliseconds, whether airbags and seatbelt pretensioners are triggered.

During operation, the control unit monitors the entire system continuously and checks the components for faults.

It shows detected faults via the airbag warning light in the instrument cluster. After an accident it stores crash data and locks itself; both affect the unit itself.

Why does the control unit 38910-73S00 fail?

The most common cause is stored crash data, even if no airbag has been triggered. Other causes are aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes, for example from a weak battery or jump-starting.

Crash data cannot be erased with a normal diagnostic tool. Airbag24 removes it during the repair.

The remaining causes lie in the electronics themselves or in their connections. Components age, solder joints can go cold, and moisture or corrosion affect plug connections.

How can you tell that the 38910-73S00 is defective?

A defect shows up as the airbag warning light in the instrument cluster, as fault messages, as a diagnostic tool without connection to the control unit and as a fault memory that cannot be cleared.

The airbag warning light stays on permanently or comes on intermittently. Fault messages in the instrument cluster and the failed connection to the diagnostic tool are further indications.

In an emergency, the airbags and seatbelt pretensioners may not deploy. Have the system checked promptly.
