Airbag control unit with part number 198672

What is the function of Airbag Control Unit 198672?

The airbag control unit with part number 198672 is the central control module for the occupant protection system, particularly in the Ferrari 575M Maranello. It continuously analyzes data from acceleration and yaw rate sensors to precisely deploy airbags and seatbelt pretensioners within milliseconds in the event of a crash, thereby protecting occupants.

As the brain of the passive safety system, this unit is responsible for interpreting signals from all relevant vehicle sensors. It must distinguish between everyday driving situations, such as hard braking, and an actual collision to prevent false activations.

Once a collision of sufficient severity is detected, the control unit sends ignition pulses to the corresponding airbag modules and seatbelt pretensioners. At the same time, it internally stores all relevant accident data.

Why does control unit 198672 fail?

The most common reason for repairing control unit 198672 is the storage of crash data after a collision. Following airbag deployment, the unit automatically locks itself and becomes inoperable, even if the hardware remains intact. This lock must be professionally reset.

Technically speaking, this is not a conventional defect but rather a manufacturer‑specified safety feature. After an accident, crash data is stored in the control unit’s non-volatile memory. This entry prevents the vehicle from being operated with a potentially compromised safety system.

The repair focuses on erasing these stored data and restoring the control unit to its original factory condition. This reinstates full functionality without requiring a costly replacement of the entire module.

How do you recognize a fault in control unit 198672?

A fault in control unit 198672 primarily manifests as a permanently illuminated airbag warning light on the instrument cluster. Often, after a crash, the control unit can no longer be accessed via diagnostic equipment, or it reports an internal, non‑erasable error indicating stored crash data.

The most noticeable symptom is the persistently lit airbag warning light, which does not extinguish even after restarting the engine—signaling a serious system malfunction.

During diagnostics at a workshop, it often becomes apparent that the control unit has lost communication or displays error codes referring to an “internal fault” or “crash event stored.” These errors cannot be cleared using standard diagnostic tools.

In which vehicles is control unit 198672 installed?

The airbag control unit with part number 198672 is specifically designed for high-performance Ferrari vehicles. At Airbag24, this control unit is repaired exclusively for the Ferrari 575M Maranello, model series F133, produced between 2002 and 2006.

What are the advantages of repairing 198672?

Repairing control unit 198672 offers significant cost savings compared to purchasing a new unit, which typically costs between €400 and €800. The repaired unit is a plug-and-play solution restored to factory settings. Additionally, a 12‑month warranty provides long-term assurance of functionality.

The key benefit is substantial cost reduction. Instead of an expensive new purchase, the existing, otherwise intact control unit is brought back into full working order.

Since the vehicle’s original control unit remains intact, no complex coding or programming work is required after installation. The repaired unit can be directly reinstalled and used.

How does the repair process work at Airbag24?

After sending the removed control unit 198672 to Airbag24, an initial inspection is performed. Subsequently, the stored crash data is professionally erased, and the unit is restored to its factory state. A final test on a diagnostic bench verifies proper functionality before reshipment.

Before removal, the vehicle battery must be safely disconnected (starting with the negative terminal), and a waiting period of at least 10 minutes should be observed to discharge any capacitors in the system. This prevents malfunctions and ensures safety.

At Airbag24, upon receipt of your unit, professional refurbishment follows. Our technicians reset the internal memory and restore full functionality. Each repair step is carefully documented and thoroughly inspected.

Finally, the control unit is tested on a specialized test bench to ensure flawless communication and proper execution of all functions as intended. Every repair comes with a 12-month warranty.
