Airbag control unit with part number 285001367

What is the function of Airbag Control Unit 285001367?

The airbag control unit with part number 285001367 is the central control module of the occupant safety system (SRS) in vehicles such as the Chrysler 300M and SsangYong Kyron. It continuously analyzes data from crash sensors and, within milliseconds, determines whether to deploy airbags and seatbelt pretensioners.

Its primary task is to ensure the safety of vehicle occupants. In the event of a collision, the module processes signals from acceleration sensors to assess the severity of the impact and activate the appropriate restraint systems accordingly.

A critical function after an accident is the storage of so‑called crash data in its internal memory. While these records document the accident, they also result in a permanent lockout of the control unit, indicated by the illuminated SRS warning light.

What defects occur in control unit 285001367?

The most common cause of failure for control unit 285001367 is the retention of crash data following an accident, which locks the device. Additionally, internal hardware faults—such as defective memory chips or processors—are typical causes, often signaled by error code B1111.

The crash‑data lockout is not a true malfunction but rather a manufacturer‑specified safety feature. Once airbags have deployed, the control unit becomes inoperable and must be professionally reset to restore full functionality of the safety system.

Internal errors diagnosed as “control unit failure” or communication issues often point to hardware defects. These can arise from aging electronic components, cold solder joints, or external factors like moisture or voltage fluctuations.

How do you recognize a defect in control unit 285001367?

A defect in control unit 285001367 primarily manifests as a permanently lit or flashing airbag warning light (SRS light) in the cockpit. Additional symptoms include specific fault codes stored in the diagnostic memory, such as B1111 (“control unit failure”), or complete loss of communication with the diagnostic tool.

The active SRS warning light is the clearest indication of a problem in the restraint system. It does not extinguish after starting the vehicle, signaling that airbags may fail to deploy in the event of another crash.

If a workshop cannot establish connection to the airbag control unit via the OBD port, this strongly suggests a serious internal defect in the module.

When fault codes are read, entries such as “internal error,” “control unit failure,” or specific side‑sensor errors directly implicate the control unit as the root cause, confirming the need for inspection or repair.

In which vehicles is control unit 285001367 installed?

The airbag control unit with part number 285001367 is specifically found in models from Chrysler and SsangYong. It is mainly used in the Chrysler 300M of the LR series and the SsangYong Kyron of the D100 series, produced between 1998 and 2015.

At Airbag24, we service part number 285001367 for the following specific vehicle models:

Chrysler: 300M (LR series) manufactured from 1998 to 2001, as well as the facelift model from 2001 to 2004.

SsangYong: Kyron (D100 series) manufactured from 2005 to 2015.

How is control unit 285001367 professionally repaired?

Upon submission to Airbag24, control unit 285001367 undergoes a professional incoming inspection. Stored crash data is then erased through a factory‑reset. For hardware defects, affected components are replaced. Each repair is backed by 2 years' statutory liability for defects.

The repair process begins with the proper removal of the control unit from the vehicle, typically located beneath the center console. Prior diagnosis at a specialized workshop to confirm the defect is recommended.

At Airbag24, technicians first precisely identify the nature of the issue. If it involves stored crash data, the unit’s internal memory is read and restored to its pre‑accident state.

If a hardware fault is detected, defective components on the circuit board are identified and replaced with new, high‑quality parts. Following completion of repairs and a final functional test, the control unit is fully operational again.

Is repairing control unit 285001367 worthwhile?

Yes, repair is the most cost‑effective solution. Compared to a new unit, which can range from €400 to €1,000, refurbishment saves up to 90% of the cost. Moreover, the original vehicle coding remains intact, eliminating the need for expensive reprogramming.

The significant cost savings are the biggest advantage. Instead of investing in an expensive new part, the original part’s functionality is restored at a fraction of the cost.

A repaired control unit is ready to install right away (“plug-and-play”), as all vehicle-specific data is preserved. By contrast, with a new part or a used unit from another vehicle, time-consuming and costly programming at an authorized workshop is often required.

Moreover, repair is a sustainable solution that helps avoid electronic waste and conserves valuable resources. With 2 years’ statutory liability for defects on the work performed, Airbag24 provides added peace of mind.
