Airbag control unit with part number A9064461242

What does the airbag control unit A9064461242 do?

The airbag control unit A9064461242 manages the restraint system (SRS) of Mercedes-Benz. It evaluates the signals from the crash sensors, decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. Faults are indicated by the airbag warning light.

The housing additionally carries the manufacturer number Bosch 0285010225. After an accident the unit stores crash data and then locks itself.

Why does the control unit A9064461242 fail?

Stored crash data is the most common cause: after an accident it remains in the memory even if no airbag has deployed, and an ordinary diagnostic tool cannot erase it. In addition, aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes come into consideration.

Airbag24 erases the crash data during the repair. The crash data alone says nothing about the condition of the electronics.

• 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 A9064461242 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. In addition, an error message appears, the diagnostic tool cannot find the control unit, and the fault memory cannot be cleared.

These signs are typical:

• The warning light in the instrument cluster stays on permanently or intermittently.
• An error message is shown in the instrument cluster.
• The diagnostic tool cannot establish a connection to the control unit.
• The fault memory cannot be cleared.

In an emergency, the airbags and seatbelt pretensioners may possibly not deploy in the case of such a defect. Have the system checked.
