Airbag control unit with part number 00052091992

What does the airbag control unit 00052091992 do?

The 00052091992 is the airbag control unit of the SRS system for Fiat. In an impact it calculates within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

Faults are shown via the airbag warning light, so you can keep track of the state of the system at all times.

An accident causes the unit to save crash data and lock itself.

Why does the control unit 00052091992 fail?

The most common cause is crash data that remains stored after an accident, even without an airbag having been triggered. Further causes are aged components, cold contacts, wetness at plug connections and voltage spikes.

Crash data cannot be erased with a normal diagnostic tool. It remains until the repair.

These causes may also come into consideration:

• ageing of electronic components
• solder joints that have gone cold
• wetness and corrosion on plugs
• voltage spikes from jump-starting or a weak battery

How can you tell that the 00052091992 is defective?

A defect can be recognised by several signs: by the airbag warning light, by a fault message, by a missing connection to the diagnostic tool and by a fault memory that cannot be erased.

The signs in detail:

• Airbag warning light in the instrument cluster stays on permanently
• Airbag warning light stays on intermittently
• Fault message in the instrument cluster
• Diagnostic tool without connection to the control unit
• Fault memory cannot be erased

In the event of a defect, airbags and seatbelt pretensioners may not trigger in an emergency. The examination will establish the cause.
