Airbag control unit with part number 38910-52RC0

What does the airbag control unit 38910-52RC0 do?

Within the restraint system (SRS) of Suzuki, the airbag control unit 38910-52RC0 is the component that evaluates the crash sensors. In a crash it decides within milliseconds which airbags and seatbelt pretensioners are triggered, and it monitors the system continuously.

Faults it detects are shown via the airbag warning light in the instrument cluster and stored in the fault memory. After a crash, the unit stores crash data and locks itself; only the repair lifts this lock.

Why does the control unit 38910-52RC0 fail?

Stored crash data is the most common cause, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

Airbag24 erases the crash data during the repair. Which of the other causes applies to your unit can only be established by a check.

How can you tell that the 38910-52RC0 is defective?

Typical signs on the 38910-52RC0 are an airbag warning light in the instrument cluster that lights up permanently or intermittently, fault messages in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

• Airbag warning light in the instrument cluster
• Fault message in the instrument cluster
• Diagnostic tool finds no connection
• Fault memory cannot be cleared

If you notice one of these signs, airbags and seatbelt pretensioners may possibly fail to trigger in an emergency. Therefore, take these warnings seriously.
