Airbag control unit with part number 52017664

What does the airbag control unit 52017664 do?

The airbag control unit 52017664 acts as the central unit of the SRS restraint system in Jeep. It processes the signals from the crash sensors, decides within milliseconds in the event of an accident whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

The sensors continuously send measurement data to the control unit, which makes the decision there. It indicates any faults found via the airbag warning light in the instrument cluster.

After an accident, the unit stores crash data and locks itself. The manufacturer's part number Bosch 0285012995 is also printed on the housing.

Why does the control unit 52017664 fail?

The most common cause is stored crash data after an accident, even when no airbag was deployed. A normal diagnostic tool cannot erase it. Other possible causes are aged electronic components, cold solder joints, moisture and corrosion, and voltage spikes.

The crash data remain stored in the memory. Further triggers are listed here:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example with a weak battery or jump starting

How can you tell that the 52017664 is defective?

The airbag warning light lights up 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.

With such a finding, airbags and seatbelt pretensioners may not deploy in an emergency. This is a clear reason not to ignore the warning.

The warning light shows the fault as soon as the control unit detects it. However, a disrupted connection to the diagnostic tool can also be caused by cables or plugs.
