Airbag control unit with part number 0285015482

What does the airbag control unit 0285015482 do?

For Tesla, the airbag control unit 0285015482 controls the restraint system (SRS). It evaluates the signals from the crash sensors and, in an accident, decides within milliseconds on the triggering of airbags and seatbelt pretensioners. After an accident it stores crash data and locks itself.

It also monitors the entire system during operation. It shows any faults found via the airbag warning light in the instrument cluster.

Why does the control unit 0285015482 fail?

The most common cause in the 0285015482 is crash data stored after an accident, even without a triggered airbag; a normal diagnostic tool cannot erase it. Other causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Airbag24 erases the crash data during the repair, and you need not prepare anything for it. The possible causes in detail are:

• Ageing electronic components in the unit
• Cold solder joints on the circuit board
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or jump-starting

How can you tell that the 0285015482 is defective?

The airbag warning light lights up on the 0285015482 either permanently or intermittently, and an error message appears in the instrument cluster. In addition, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. Have the warning light checked promptly, even if the vehicle still drives normally.
