Airbag control unit with part number A2469002313

What does the airbag control unit A2469002313 do?

In an accident the airbag control unit A2469002313 decides within milliseconds which airbags and seatbelt pretensioners to trigger. To do so it evaluates the signals from the crash sensors. At the same time it monitors the entire system for Mercedes-Benz and displays faults on the airbag warning light.

The manufacturer number Bosch 0285012558 is also printed on the housing.

During operation the unit checks the connected components and stores irregularities. After an accident it stores crash data and locks itself.

Why does the control unit A2469002313 fail?

The most common cause of the A2469002313 is stored crash data, even if no airbag has deployed. These cannot be deleted with a normal diagnostic tool. Other causes are aged electronics, cold solder joints, moisture and voltage spikes.

The causes in detail:

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

The crash data remains in the unit even if no airbag has deployed in the accident. For this reason a look at the plug alone is not enough.

How can you tell that the A2469002313 is defective?

A defect on the A2469002313 shows first at the airbag warning light in the instrument cluster, which lights up constantly or at times. A fault message may also appear in the instrument cluster. Then airbags and seatbelt pretensioners may fail to trigger in an emergency.

A diagnostic tool that cannot establish a connection to the control unit is another sign. A fault memory that cannot be cleared also points to a problem in the system.

The warning light exists to make a defect visible, and its warning calls for prompt investigation.
