Airbag control unit with part number 04602258AG

What is the function of the airbag control unit 04602258AG?

The airbag control unit with part number 04602258AG is a central safety module from Bosch (internal number 0 285 001 660), installed as an original Mopar part in Chrysler models such as the second-generation Sebring JS and Stratus. It controls and monitors the entire restraint system, analyzes sensor data, and deploys the airbags and seatbelt pretensioners in the event of a crash.

As the “brain” of the passive safety system, this control unit continuously processes information from the vehicle’s acceleration and crash sensors. If it detects a collision exceeding predefined thresholds, it sends ignition signals to the corresponding airbags and seatbelt pretensioners within milliseconds. At the same time, it stores relevant crash data—known as crash data—in its internal memory.

The proper functioning of this device is critical for occupant safety. Any malfunction in the system results in deactivation of the airbags and is indicated to the driver by the SRS warning light.

Why does the control unit 04602258AG fail?

The most common cause of failure for the control unit 04602258AG is the storage of crash data after an accident, which triggers a safety lock on the system. Another frequent issue is spontaneous electronic malfunctions in internal components, leading to airbag deactivation and the SRS warning light remaining constantly illuminated.

Following a crash, the control unit automatically locks itself to prevent unintended re‑deployment. This lock is permanent and can only be lifted through a professional reset of the internal memory. The system then reports an internal error, even though the hardware itself is often undamaged.

Independently of accidents, random electronic faults may also occur. Technically similar control units, such as the related part number 04602258AF, exhibit comparable symptoms, including defective electronic components or failures in sensor inputs. In these cases, there is a genuine hardware defect requiring component‑level repair.

How do you recognize a fault in the 04602258AG?

The clearest symptom of a fault in the control unit 04602258AG is a flashing or continuously lit SRS airbag warning light on the instrument panel. This signal indicates that the restraint system is non‑functional and the airbags will not deploy in the event of a crash. Immediate inspection at a specialized workshop is therefore essential.

The illuminated warning light is a direct result of the control unit’s self‑diagnosis. Once a critical error—whether caused by stored crash data or a hardware defect—is detected, the system disables the airbags and visually alerts the driver.

In some cases, the control unit may become inaccessible via the OBD interface. Diagnostic tools are unable to establish communication or read out any fault codes, which likewise points to a severe internal malfunction of the module.

In which vehicles is the control unit 04602258AG installed?

This specific airbag control unit is found in certain Chrysler models. At Airbag24, we service part number 04602258AG for the Chrysler Sebring JS series (2006–2010) as well as for the second generation of the Chrysler Stratus (2000–2006).

How is the control unit 04602258AG professionally repaired?

Upon receipt at Airbag24, the control unit 04602258AG undergoes a standardized repair process. This begins with a detailed fault analysis. Depending on the root cause, stored crash data is erased or defective electronic components are replaced. A final functional test ensures that the unit is ready for installation and fully operational.

First, experienced mechatronics technicians perform a comprehensive diagnosis to pinpoint the exact cause of the fault. They determine whether only crash data has been stored or if there is a deeper hardware defect.

In the next step, actual repairs take place. Stored crash data is securely and completely removed from the control unit’s memory. If a component defect is identified, faulty parts are replaced with new, high‑quality spare parts.

After repair, the control unit undergoes rigorous final testing on a dedicated test bench. This guarantees that all functions operate flawlessly. The unit is returned ready for installation (plug-and-play) and covered by our 2 years’ statutory liability for defects.

Is Repairing the 04602258AG Worth It?

Yes, repairing the control unit 04602258AG is a technically and economically sensible solution. It saves you up to 800 euros compared to purchasing a new part. Moreover, the repaired unit is ready for immediate installation—no additional workshop programming is required—and comes with 2 years’ statutory liability for defects.

The financial benefit is substantial. A brand-new part is often disproportionately expensive, whereas repair offers a professional, reliable alternative at a fraction of the cost. This significant savings makes repair the preferred choice for both workshops and private customers.

An additional key advantage is that the repaired control unit can be reinstalled right away. No time-consuming, costly coding or programming at an authorized dealer is necessary, saving you both time and money.
