Airbag control unit with part number 50564740

What does the airbag control unit 50564740 do?

The airbag control unit 50564740 controls the airbags and seatbelt pretensioners of Dodge within the restraint system (SRS). In an accident it evaluates the crash sensors and decides on triggering within milliseconds.

The manufacturer's part number Bosch 0285015660 is also printed on the housing. In operation the unit monitors the system continuously and shows faults via the airbag warning light.

If an accident has occurred, the unit stores crash data and locks itself. Only the repair lifts this lock.

Why does the control unit 50564740 fail?

Stored crash data after an accident is the most common reason for a failure of 50564740, even if no airbag was triggered. A normal diagnostic tool cannot remove this data.

Airbag24 removes the crash data during the repair. Other possible causes include:

• electronic components that wear out over the years
• cold solder joints on the circuit board
• moisture and rust at the plug connections
• voltage peaks, for example with a weakened battery or a jump start

How can you tell that the 50564740 is defective?

A permanently or intermittently lit airbag warning light in the instrument cluster is a clear sign at the 50564740. An error message in the instrument cluster may accompany it.

In addition, the diagnostic tool may not be able to connect to the control unit, and the fault memory remains even if you try to clear it.

In such a state, airbags and seatbelt pretensioners may possibly not trigger in an emergency. A prompt check is therefore advisable.
