Airbag control unit with part number 04671419AD

What is the function of the airbag control unit 04671419AD?

The airbag control unit with part number 04671419AD is the central control module for the occupant protection system in Chrysler PT Cruiser models. As an original Mopar component, it processes data from acceleration and crash sensors to precisely deploy airbags and seatbelt pretensioners in the event of a collision. Additionally, it stores all relevant crash data and locks itself after an incident.

This control unit serves as the brain of the passive safety system. It continuously monitors signals from crash sensors distributed throughout the vehicle. If, based on sensor data, it detects a collision exceeding a predefined threshold, it sends ignition commands to the corresponding airbag modules and seatbelt pretensioners within milliseconds.

Even if no airbags were deployed following a crash, the crash data remains permanently stored in the control unit’s internal memory. This feature ensures safety by preventing the reuse of potentially damaged systems, but it also results in deactivation of the entire airbag system until the data is professionally erased.

Why does the control unit 04671419AD fail?

The most common cause of failure for the 04671419AD control unit is the storage of crash data after an accident, which triggers an internal lockout. Other causes include electronic malfunctions due to component aging, defects in internal processors or memory chips, and damage caused by moisture ingress leading to corrosion and short circuits on the circuit board.

The primary reason is the programmed storage of crash data. Even minor collisions—such as those triggering only the seatbelt pretensioners—result in an entry being logged in the fault memory that cannot be cleared using standard diagnostic tools. The system then reports a fault and shuts down.

Electronic failures are another frequent issue. Internal components like processors, voltage regulators, or memory chips (EEPROM) may fail due to age or fluctuations in the vehicle’s electrical system. These often lead to internal errors that prevent communication with the control unit or block its functionality.

Environmental factors, such as water damage, can also irreparably harm the control unit. Moisture penetration causes corrosion on sensitive traces and solder joints, resulting in short circuits and complete electronic failure.

How do you recognize a defect in the 04671419AD?

A defect in the 04671419AD control unit primarily manifests as a continuously illuminated or flashing SRS airbag warning light on the instrument panel. Additionally, fault codes stored in the memory—such as “internal error” or “side‑sensor error”—cannot be cleared. In many cases, the control unit becomes inaccessible to diagnostic equipment or continues to report stored crash data.

The most obvious symptom is the active airbag warning light, indicating to the driver that the entire restraint system is disabled and offers no protective function in the event of a crash. The light often remains on continuously, even immediately after starting the engine or following a brief diagnostic test lasting about 30 seconds.

During workshop diagnostics, the problem appears as persistently stored fault codes. Typical entries include “internal control unit error,” faults related to seatbelt pretensioners, or side‑impact sensors that remain unresolved even after attempting a reset.

Another clear sign is the “crash data stored” entry in the fault memory, confirming that the control unit has been locked following an accident and requires specialized reprogramming to restore full functionality.

In severe cases—typically involving complete hardware failure—communication with the control unit becomes impossible. The diagnostic tool receives no response, making replacement or repair unavoidable.

In which vehicles is the 04671419AD control unit installed?

- Chrysler PT Cruiser Convertible PT

How does the repair of the 04671419AD proceed at Airbag24?

Repair at Airbag24 begins with a detailed fault analysis of the submitted 04671419AD control unit. Stored crash data is then professionally erased, and any defective electronic components are replaced. Following restoration of the original programming, a comprehensive functional test is performed. We provide a 12-month warranty on the entire repair process.

Before removing the control unit, a specialized workshop should read out the fault memory to confirm that the defect originates from the control unit itself and not from external components such as sensors or wiring. This fault log should be included with the shipment.

Upon receipt at Airbag24, the control unit undergoes a comprehensive incoming inspection. Our technicians analyze the reported faults and identify the exact cause at the component level. The core of the repair involves electronic refurbishment, replacement of defective components, and secure erasure of crash data.

Following successful repair, the control unit is tested on a dedicated test bench to verify flawless functionality across all systems. The device is returned in plug-and-play condition and ready for immediate installation.
