Airbag control unit with part number 00052078057

What does the airbag control unit 00052078057 do?

The airbag control unit 00052078057 is the central component of the restraint system (SRS) in the Fiat. It evaluates the crash sensors and decides in an accident which airbags and seatbelt pretensioners are triggered.

Between accidents, it monitors the system continuously. Faults appear as an indication on the airbag warning light.

After an accident, the unit stores crash data and locks itself.

Why does the control unit 00052078057 fail?

On the control unit 00052078057, stored crash data is the most common cause, even if no airbag has deployed. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data cannot be deleted with a normal diagnostic tool. Airbag24 removes it during the repair.

The other causes in overview:

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

Which of these applies in the individual case only becomes clear during the inspection.

How can you tell that the 00052078057 is defective?

A defect in the 00052078057 shows itself through the airbag warning light in the instrument cluster, through fault messages in the instrument cluster, through a diagnostic tool without a connection to the control unit, or through a fault memory that cannot be cleared.

These signs are important indicators:

• Airbag warning light stays on permanently
• Airbag warning light comes on from time to time
• Fault message in the instrument cluster
• Diagnostic tool does not find the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may fail to deploy. An inspection is therefore the right next step.
