Airbag control unit with part number A2C330470000

What is the function of the airbag control unit A2C330470000?

The airbag control unit A2C330470000 is the central control module for the occupant protection system in the second-generation Ford Ka (RU8). It processes data from the acceleration sensors to precisely and rapidly deploy the airbags and seatbelt pretensioners in the event of a collision, thereby protecting occupants from serious injuries.

As an original equipment (OE) part, this control unit is specifically tailored to the vehicle architecture of the Ford Ka 2 (model years 2008–2016). It is typically located in the center tunnel near the gearshift lever and serves as the brain of the entire airbag system.

Its primary task is to continuously monitor and evaluate signals from the crash sensors. When the system detects a collision, the control unit sends ignition pulses to the appropriate restraint devices. Without a functioning control unit, the entire airbag system becomes inoperable.

Why does the control unit A2C330470000 fail?

The main cause of failure for the control unit A2C330470000 is internal electronic defects. These often arise due to age-related material fatigue in components such as microprocessors and capacitors on the circuit board. Moisture or severe vibrations can further accelerate these processes, leading to complete failure.

Another common reason is the storage of crash data after an accident. Following an airbag deployment, the control unit locks itself internally and requires professional reset procedures. Simply clearing the fault memory via a diagnostic tool is insufficient in such cases.

This component is also known under other reference numbers that are technically identical. These include part numbers A2C30470000, 51925902, 51889815, 51925901, A2C30469900, 51805046, and 53284384. A defect in any of these numbers manifests with the same symptoms.

How do you recognize a defect in the A2C330470000?

The most obvious sign of a defect in the airbag control unit A2C330470000 is the permanently illuminated or flashing red airbag warning light on the instrument cluster. The system performs a self-test, indicating a serious malfunction that results in the failure of the restraint systems.

Another clear symptom is the lack of communication with the control unit. If a workshop attempts to read the fault memory using a diagnostic tool, the control unit appears unreachable or unresponsive, pointing to a profound internal hardware failure.

Consequently, the entire airbag system is deactivated. In the event of a crash, the airbags and seatbelt pretensioners would not deploy, posing a significant safety risk and resulting in failure during the mandatory technical inspection.

In which models is the A2C330470000 installed?

The airbag control unit with part number A2C330470000 was specifically developed for the second-generation Ford Ka. At Airbag24, we repair this control unit for the following specific model, particularly for the 1.2-liter engine with 69 horsepower.

Ford: Ka 2 (RU8), model years 2008–2016

How is the A2C330470000 repaired?

Repair is a proven and safe alternative to costly new purchases. At Airbag24, restoration follows a standardized process that ensures full functional recovery. This includes diagnosis, electronic repairs at the component level, and a final functionality test.

After the removed control unit arrives at Airbag24, technicians conduct a thorough analysis. Defective electronic components, such as capacitors or microprocessors on the circuit board, are identified and replaced. Stored crash data is also professionally erased during this process.

Subsequently, the repaired unit undergoes testing on a bench to confirm flawless communication and operation. Unlike used control units with unknown histories, a repaired unit offers full functionality and safety, backed by a 12-month warranty.

What shipping options are available?
