Airbag control unit with part number 00052058730

What does the airbag control unit 00052058730 do?

The airbag control unit 00052058730 is the central control unit of the restraint system (SRS) for Fiat. It checks the signals from the crash sensors and determines in an accident which airbags and seatbelt pretensioners are triggered.

The evaluation takes place within milliseconds. The unit also monitors the system's components and shows faults via the airbag warning light.

After an accident it stores crash data and locks itself.

Why does the control unit 00052058730 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool does not erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

The crash data remains stored in the unit. This is why a simple read-out alone does not help.

Aged electronic components and cold solder joints lead to malfunctions. Moisture and corrosion on the plug connectors disrupt signal transmission.

Voltage spikes, for example from a weak battery or a jump start, are a further factor.

How can you tell that the 00052058730 is defective?

You can recognise a defect in the control unit 00052058730 by the airbag warning light, by fault messages in the instrument cluster, by a diagnostic tool that has no connection, or by a fault memory that cannot be cleared.

Watch out for the following signs:

• Airbag warning light lit constantly or intermittently
• Fault message in the instrument cluster
• Diagnostic tool has no connection to the control unit
• Fault memory cannot be cleared

In this case airbags and seatbelt pretensioners may not deploy in an emergency. Have the findings checked.
