Airbag control unit with part number 38910-73R00

What does the airbag control unit 38910-73R00 do?

The airbag control unit 38910-73R00 is the central control unit of the restraint system (SRS) for Suzuki. It evaluates the signals from the crash sensors and decides in a crash which airbags and seatbelt pretensioners are triggered.

The decision is made within a fraction of a second. In addition, the unit monitors the system continuously and shows faults via the airbag warning light.

After an accident, it stores crash data and locks itself. Only the repair lifts the lock.

Why does the control unit 38910-73R00 fail?

Crash data stored after an accident is the most common cause, even if no airbag has deployed. Further causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A normal diagnostic tool cannot erase this crash data. Airbag24 erases it during the repair.

The other triggers mainly affect the electronics. Components age, solder joints can be cold, and moisture and corrosion attack plug connections.

Voltage spikes arise, for example, from a weak battery or from a jump start. The test shows whether any of these causes applies.

How can you tell that the 38910-73R00 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently as soon as the 38910-73R00 has detected a fault. An error message, a lost connection to the diagnostic tool and a fault memory that cannot be cleared may also appear.

If the warning light comes on, take it seriously and have the fault memory read out. The light is a warning that should not be ignored.

A diagnostic tool that cannot establish a connection, and a fault memory that cannot be cleared, also indicate a problem.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger.
