4.8What is an Abarth 124 Spider 348 airbag control unit?
The airbag control unit is the central control unit of the restraint system (SRS) in the Abarth 124 Spider 348. It evaluates the signals from the crash sensors, decides within milliseconds in an accident which airbags and seatbelt pretensioners deploy, and continuously monitors the system.
Three parts work together: sensors detect the deceleration of the vehicle, the control unit evaluates the values, and the airbags and seatbelt pretensioners are fired only when necessary. The control unit is installed in the Abarth 124 Spider 348 (2017 to 2019) and comes from Bosch.
It reports faults in the system via the airbag warning light. After an accident it stores crash data and locks itself.
Why is the Abarth 124 Spider 348 airbag control unit defective?
The most common cause is crash data stored after an accident, even if no airbag deployed; a normal diagnostic tool cannot erase it. Other possible causes are aged electronic components, cold solder joints, moisture and corrosion on connectors, and voltage spikes.
A typical sign is an airbag warning light that stays on permanently. Often the fault memory cannot be cleared, or the diagnostic tool cannot connect to the control unit.
Voltage spikes occur, for example, with a weak battery or when jump-starting. Over the years, components on the circuit board also age, solder joints can develop contact problems, and moisture attacks connectors. Which cause applies to your unit is only clarified by the inspection.
Common error codes for Abarth 124 Spider 348 airbag control unit repair
The error codes for the Abarth 124 Spider 348 airbag control unit mainly concern communication with the control unit and the squib circuits of the airbags. They go hand in hand with a permanently lit airbag warning light.
These codes are known for this control unit:
- U0151 → Communication with the airbag control unit lost
- B0001 → Driver airbag: squib circuit interrupted
Error codes are read out with a diagnostic tool. A code alone does not reliably show that the control unit is defective: connectors, wiring or an airbag module can also be the cause. Only the inspection clarifies where the fault actually lies.
What part numbers are available for the Abarth 124 Spider 348 airbag control unit repair?
The part number is on the label of the control unit and determines the exact version, because within a model series there are different numbers depending on equipment and year of manufacture. Several numbers are known for the Abarth 124 Spider 348.
The list contains the part numbers known so far and makes no claim to completeness:
- N243-57K30 (Bosch)
- NA1J-57K30
Compare the number on your unit with this list. This only ensures that it is the right unit; whether it is defective is shown only by reading out the fault memory or by the inspection.
The route to repair is short: first have the fault memory read out, disconnect the battery and remove the control unit. Then create a repair order online and send in the unit. Processing at Airbag24, with inspection, repair and testing, usually takes 3–4 working days. 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.
