Airbag control unit with part number A9064461642

What does the airbag control unit A9064461642 do?

The A9064461642 controls the restraint system (SRS) in Mercedes-Benz. It analyses the signals from the crash sensors and, after an accident, decides within milliseconds which airbags and seatbelt pretensioners trigger. It also monitors the system and reports faults via the airbag warning light.

The manufacturer's number Bosch 0285010351 is also printed on the housing, and you will find it when comparing as well.

During operation the control unit checks its surroundings, i.e. sensors, triggers and cables. After an accident it stores crash data and locks itself.

Why does the control unit A9064461642 fail?

The most frequent fault on the A9064461642 relates to crash data that remain stored after an accident, even if no airbag has fired. An ordinary diagnostic tool cannot erase them; Airbag24 erases them during the repair.

Whether an airbag fires does not decide whether the unit stores data. That is exactly why, with a fault message, you need to look closely even when there is no visible damage.

Further causes in general are:

• Electronic components worn out with age
• Cold solder joints on the circuit board
• Moisture and corrosion at the plug connectors
• Voltage spikes, for example from a weak battery or jump start

Which of these applies in your case can only be clarified on the test bench.

How can you tell that the A9064461642 is defective?

A defect is indicated mainly by an airbag warning light that stays on, a message in the instrument cluster, a diagnostic tool without access to the control unit and a fault memory that cannot be emptied. In an emergency, airbags and seatbelt pretensioners may then be unable to trigger.

A single sign does not prove any damage, but if the warning is ignored, the system may fail to work as intended. Under certain circumstances the overall picture only becomes clear during a check with the diagnostic tool.
