Airbag control unit with part number 193200

What is the function of Airbag Control Unit 193200?

The airbag control unit with part number 193200 is the central control module of the occupant restraint system (SRS) in the Ferrari 575M Maranello (F133). Its primary task is to process data from crash sensors, ensuring that airbags and seatbelt pretensioners are deployed precisely and at the right moment during a collision. Additionally, it continuously monitors all system components.

As the brain of the safety system, unit 193200 constantly processes information from the vehicle’s acceleration sensors. In the event of a collision, its internal logic determines within milliseconds which restraint devices need to be activated. After deployment, the control unit stores relevant crash data in non-volatile memory, enabling later analysis but locking the device for further operation.

Furthermore, the control unit performs continuous self-diagnosis, checking electrical resistances in the ignition circuits for airbags and seatbelt pretensioners, as well as the functionality of connected sensors. Detected faults are indicated by the illumination of the airbag warning light on the instrument cluster and logged in the fault memory.

What defects occur in control unit 193200?

Typical defects of the Ferrari airbag control unit 193200 include stored crash data after an accident that locks the unit, as well as internal hardware failures. These encompass defective memory chips (EEPROM/Flash), damaged circuit traces, or cold solder joints, leading to communication breakdowns or persistent error messages.

The most common reason for repair is the storage of crash data. Even after a minor accident where not all airbags deploy, the control unit may be marked as “used up.” In this state, the airbag warning light remains permanently illuminated, even if all external SRS components—such as airbags and seatbelt pretensioners—have already been replaced. An electronic refurbishment clears these data and restores the unit to operational condition.

Another defect is an internal hardware failure, often signaled by error codes like B1006 (as a general example). The root cause usually lies in faulty memory modules storing vehicle configuration and operating data. Damaged solder joints, circuit traces, or protective circuits compromised by moisture or overvoltage can also result in sporadic or permanent malfunctions.

Defects in the ignition circuits of airbags or seatbelt pretensioners (e.g., B1932—driver airbag circuit interrupted) may likewise originate directly on the control unit’s circuit board. Issues with connector strips or driver stages are potential sources of trouble that can be resolved through professional repair.

How do you recognize a defect in control unit 193200?

A defect in control unit 193200 primarily manifests as the airbag warning light remaining constantly illuminated in the cockpit. Additional symptoms include disrupted or completely absent communication with the diagnostic tool, along with specific fault entries such as “crash data stored” or “internal control unit error.”

The clearest indication is the persistently lit airbag warning light. It does not extinguish after starting the vehicle, signaling a serious malfunction in the safety system—often originating directly from the control unit.

Often, a workshop cannot establish communication with the airbag control unit. The diagnostic tool then reports “control unit unresponsive” or “communication impossible,” pointing to a severe internal defect.

If error codes reveal stored crash data or internal hardware faults (e.g., memory errors), the root cause is clearly located within the control unit itself. Even after all visible damage has been repaired following an accident, the warning light stays on due to the retained data.

In which vehicles is control unit 193200 installed?

The airbag control unit with part number 193200 is specifically designed for the Ferrari 575M Maranello of the F133 series, produced roughly between 2002 and 2006. At Airbag24, we offer expert repair services exclusively for this particular control unit.

At Airbag24, we service part number 193200 for the following model:

Ferrari 575M Maranello (F133 series, circa 2002–2006)

What are the advantages of repair?

Repairing the original control unit 193200 is significantly more cost-effective than purchasing an expensive new part from Ferrari. Moreover, the original vehicle configuration is preserved, eliminating the need for time-consuming reprogramming. With over 20 years of experience, electronic refurbishment represents a proven and sustainable solution.

A new airbag control unit for a Ferrari often comes with substantial costs. Repairing it offers savings of up to 70% while restoring the original part’s full functionality.

Since the repaired control unit remains precisely matched to your vehicle, no complicated coding or re-learning procedures are required after installation. The vehicle performs just as it did with the original, fully functional unit. We also provide 2 years' statutory liability for defects on every repair performed.

How does the repair of control unit 193200 work?

The process begins with a precise fault diagnosis on the vehicle. After removal and shipment to Airbag24, a detailed electronic analysis is conducted on our test bench. The repair includes resetting crash data, replacing defective components, and performing a final functional test before returning the unit with 2 years’ statutory liability for defects.

First, a specialized workshop must confirm that the fault lies in control unit 193200 itself, rather than in the wiring or sensors. A diagnostic report is essential for this step.

The removed control unit is carefully padded and sent to us. Please include a detailed fault description and the readout log to expedite the analysis.

At Airbag24, our technicians perform an incoming inspection. They then professionally erase crash data, replace faulty memory chips or other components, and rework any cold solder joints. A comprehensive final test simulates real‑world driving conditions to ensure flawless operation.

Following successful repair, the control unit is returned to you. After reinstalling it, you only need to clear the fault memory in the vehicle to fully reactivate the system.
