Airbag control unit with part number 38910M68PB0

What does the airbag control unit 38910M68PB0 do?

In the Suzuki restraint system, the airbag control unit 38910M68PB0 evaluates the signals from the crash sensors. In an accident it decides within milliseconds on airbags and seatbelt pretensioners, and it monitors the system continuously.

Faults are reported by the unit via the airbag warning light in the instrument cluster.

After an accident, it stores crash data and locks itself. This is part of the system design.

Why does the control unit 38910M68PB0 fail?

Stored crash data after an accident is the most common cause for the 38910M68PB0, even if no airbag has deployed. Other causes include aged electronics, cold solder joints, moisture and corrosion at plugs, and voltage spikes.

Crash data cannot be erased with an ordinary diagnostic tool. It therefore remains in the control unit.

Aged components and cold solder joints are causes within the unit itself. Moisture and corrosion affect the plugs, and voltage spikes occur, for example, with a weak battery or jump-starting.

How can you tell that the 38910M68PB0 is defective?

A defect on the 38910M68PB0 shows through the airbag warning light in the instrument cluster, which stays on permanently or intermittently, and through further signs in the vehicle.

These signs occur individually or together:

• Airbag warning light in the instrument cluster stays on permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool does not find the control unit
• Fault memory cannot be erased

If the control unit is faulty, airbags and seatbelt pretensioners may not deploy in an emergency. Therefore, have the cause clarified promptly.
