Airbag control unit with part number 52082505

What does the airbag control unit 52082505 do?

The airbag control unit 52082505 coordinates the restraint system (SRS) of Fiat. It evaluates the signals from the crash sensors, determines within milliseconds in a crash which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After a crash, it stores crash data and locks itself.

The manufacturer number Bosch 0285014251 is also printed on the housing.

The unit reports faults via the airbag warning light in the instrument cluster. If everything is in order, the light stays off.

Why does the control unit 52082505 fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. Other causes are aged electronic components, cold solder joints, moisture and corrosion at connectors, and voltage spikes, for example from a weak battery or jump-starting.

Crash data remains stored until it is deleted. A normal diagnostic tool cannot do this, so Airbag24 deletes it as part of the repair.

Aged components lose reliability over time. Cold solder joints lead to intermittent contact, and moisture with corrosion affects connectors. Voltage spikes put additional strain on the electronics.

How can you tell that the 52082505 is defective?

A defect shows up on the airbag warning light, as an error message in the instrument cluster, as a missing connection to the diagnostic tool, or as a fault memory that cannot be cleared.

Typical signs at a glance:

• The airbag warning light is on permanently or intermittently.
• An error message appears in the instrument cluster.
• The diagnostic tool cannot connect to the control unit.
• The fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may not trigger in the event of a defect. It is therefore worth having the fault memory read out promptly.

For the same vehicles, we also repair control units with the part numbers 285010656, 285010857, 51810463, 51881770, 51976890.

How does the repair of the 52082505 work?

First have the fault memory read out and enclose the log. Then disconnect the battery and remove the control unit. Next, create a repair order online and send in the well-packed unit. Airbag24 checks it, replaces defective components, deletes the crash data and runs a function test.

The sequence is mandatory for safety reasons. The unit is removed only after the battery has been disconnected.

Processing at Airbag24 covers checking, repairing and testing, and usually takes 3–4 working days. Afterwards your own unit is returned to you.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
