Airbag control unit with part number 110618

What is the function of Airbag Control Unit 110618?

The Airbag Control Unit 110618 is the central control module of the Occupant Restraint System (SRS), specifically designed for the Ferrari F512 M from the F110 series (1994–1996). Its primary task is to process sensor data and, in the event of a crash, precisely deploy the airbags and seatbelt pretensioners at the correct moment. It ensures the proper functioning of the entire safety system.

As the “brain” of the passive safety system, this component continuously monitors all connected sensors, such as acceleration sensors. When these sensors detect data indicating a collision, the control unit determines within milliseconds whether and how to activate the restraint devices.

For an exclusive vehicle like the Ferrari F512 M, the precise operation of this control unit is crucial, as spare parts for such classic cars are extremely limited.

Why does Control Unit 110618 fail? Common defects.

The most frequent cause of failure for Control Unit 110618 is the storage of crash data after an accident, which intentionally locks the unit. In addition, internal electronic faults on the circuit board can lead to malfunctions. Insufficient supply voltage or mechanical damage may also result in defects.

Storing crash data is a manufacturer‑imposed safety feature. After an airbag deployment, the control unit is internally locked to prevent reuse. However, this condition can be reversed through specialized electronic repair.

Internal electronic faults are another common issue. These are hardware defects on the circuit board caused by component aging or poor solder joints, disrupting proper signal processing.

How do you recognize a defect in Control Unit 110618?

A defect in Control Unit 110618 is unmistakably indicated by a permanently illuminated or flashing airbag warning light on the Ferrari’s instrument cluster. During diagnostics, specific fault codes such as B1111 (control unit defective) or messages about an internal error (MRS internal error) are often read out, directly pointing to the control unit.

The airbag indicator light does not extinguish after starting the vehicle as usual within a few seconds but remains constantly lit. This is a clear sign that the SRS has detected a serious malfunction and will not function properly in the event of a crash.

The fault codes stored in the error memory are essential for accurate diagnosis. Errors like “B1111” or “internal control unit error” confirm that the root cause lies directly within the control unit itself, rather than in external components such as sensors or wiring.

In which vehicles is Control Unit 110618 installed?

The Airbag Control Unit with part number 110618 is a highly specialized component primarily fitted in classic Ferrari models. It is directly associated with the Ferrari F512 M from the F110 series, manufactured between 1994 and 1996. Similar models, such as the Ferrari 512 TR F110, may also be affected.

What are the advantages of repair over buying a new unit?

Repairing Control Unit 110618 offers significant benefits, especially for a classic vehicle like the Ferrari F512 M. Not only is it considerably more cost‑effective than purchasing a rare and expensive new part—up to €750—but it also eliminates the need for time‑consuming reprogramming. The repaired original unit functions immediately after installation (plug & play).

A key factor is cost savings. A new control unit for a Ferrari from this era, if available at all, can cost up to €750, often plus additional expenses for brand‑specific programming at a workshop.

Since the repair preserves the original unit while simply resetting its data, there is no need to relearn the vehicle’s systems. The control unit is removed, repaired, and reinstalled—a straightforward plug‑and‑play solution.

Moreover, repair provides a sustainable and rapid solution, as sourcing new parts for vintage and young‑timer cars is often lengthy and complicated.

How is Control Unit 110618 professionally repaired?

Professional repair at Airbag24 focuses on electronically restoring the original unit. Following careful removal and shipment, the control unit’s internal memory is reset, and any stored crash data is erased. The device then undergoes a thorough inspection for additional electronic defects, ensuring full functionality with a 12‑month warranty.

The process begins with the correct removal of the unit. In the Ferrari F512 M, it is often located in the center console, under the front seats, or behind a cover. After sending it to Airbag24, technicians perform an initial inspection.

The core of the repair involves erasing the crash data and resetting the software to factory settings using specialized equipment. At the same time, the circuit board is examined for visible damage, cold solder joints, or defective components.

Following successful restoration, the control unit is prepared for return shipment. After reinstalling it in the vehicle and clearing the fault memory, the airbag system is fully functional again, as confirmed by the warning light turning off after starting the engine.
