Airbag control unit with part number 38910M69PB0

What does the airbag control unit 38910M69PB0 do?

The 38910M69PB0 is the airbag control unit of the restraint system of Suzuki. It evaluates the signals from the crash sensors and decides in an impact within milliseconds which airbags and seatbelt pretensioners are triggered.

In addition, it checks the system continuously for faults. A detected fault appears via the airbag warning light in the instrument cluster.

After an accident the control unit stores crash data and locks itself. This point accompanies every later repair.

Why does the control unit 38910M69PB0 fail?

Crash data stored after an accident is the most common cause for the 38910M69PB0, even if no airbag has deployed. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes come into consideration as further causes.

A normal diagnostic tool cannot erase this crash data. It therefore stays in the unit until Airbag24 removes it during repair.

The other causes mainly concern wear and connections. Moisture and corrosion attack the plug connections, and voltage spikes occur, for example, with a weak battery or a jump-start.

How can you tell that the 38910M69PB0 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. A defect on the 38910M69PB0 also shows as an error message in the instrument cluster, as a missing connection of the diagnostic tool, or as a fault memory that cannot be cleared.

• Warning light that stays on permanently
• Warning light that only comes on intermittently
• Error message in the instrument cluster
• Diagnostic tool without connection to the control unit
• Fault memory that cannot be cleared

These signs indicate that airbags and seatbelt pretensioners may not deploy in an emergency. Such a sign therefore needs prompt clarification.
