Airbag control unit with part number 90565938

What does the airbag control unit 90565938 do?

As a central unit, the airbag control unit 90565938 controls the restraint system (SRS) for Opel. It evaluates crash sensors, determines in a crash within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. Reported faults appear on the airbag warning light.

The housing also carries the manufacturer number Continental 5WK4186. So when you compare the label, you can use both numbers.

After a crash, the unit stores crash data and locks itself.

Why does the control unit 90565938 fail?

Most often the cause is crash data from an accident, even if no airbag has deployed, because a standard diagnostic tool cannot erase it. In addition come aging of the electronics, cold solder joints, moisture, corrosion and voltage spikes.

The crash data arises because the unit records the event. Airbag24 erases it during the repair.

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

How can you tell that the 90565938 is defective?

A defect in the control unit shows through the airbag warning light, through fault messages in the instrument cluster, or through a missing connection of the diagnostic tool. In an emergency, airbags and seatbelt pretensioners may then not deploy.

Typical signs are:

• airbag warning light on permanently or intermittently
• fault message in the instrument cluster
• diagnostic tool receives no connection to the control unit
• fault memory cannot be cleared

The warning light is the clearest signal, because it reports a detected fault directly to the driver.

If any of these signs appears, respond promptly and have the system checked.
