Airbag control unit with part number 38910-77M00

What does the airbag control unit 38910-77M00 do?

As the SRS control unit, the 38910-77M00 controls the airbags and seatbelt pretensioners of Suzuki. The crash sensors continuously supply it with measured values, from which it derives the triggering in an accident within milliseconds, and it monitors the entire system.

It shows detected faults via the airbag warning light. After an accident it stores crash data and then remains locked.

The monitoring runs continuously in the background.

Why does the control unit 38910-77M00 fail?

The most common cause in the 38910-77M00 is crash data stored after an accident, even if no airbag was triggered. Further causes come into consideration:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

Crash data cannot be erased with a normal diagnostic tool. Airbag24 erases it during the repair and at the same time checks the other points.

How can you tell that the 38910-77M00 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently when there is a defect on the 38910-77M00. In addition, an error message appears in the instrument cluster, and the diagnostic tool finds no connection to the control unit.

In this state the fault memory cannot be cleared, which likewise points to the control unit. In an emergency, airbags and seatbelt pretensioners may not be triggered while the control unit is faulty.
