Airbag control unit with part number 44323373

What is the function of Airbag Control Unit 44323373?

The airbag control unit with part number 44323373 is the central control module for the occupant safety system (SRS) in the Land Rover Freelander 1. It processes data from crash sensors and, in the event of a collision, deploys airbags and activates seatbelt pretensioners. This component is also known under the numbers YWC106360 and EHM500370PUY.

As the “brain” of the passive safety system, the SRS module 44323373 interprets signals from various acceleration sensors throughout the vehicle. Based on this data, it determines within milliseconds whether a collision has occurred and which restraint systems—such as front or side airbags, as well as seatbelt pretensioners—should be activated to provide optimal protection for occupants.

The part number 44323373 is one of the primary OEM numbers for the Land Rover Freelander 1 (L314). For the same component, compatible part numbers YWC106360 and EHM500370PUY are also available and relevant during repairs or replacements.

Why does control unit 44323373 fail?

The most common cause of failure for control unit 44323373 is the storage of crash data after an accident, which locks the device. Additional malfunctions arise from external factors such as broken wiring, incorrect connections, or loose plug-in connectors to the SRS system, disrupting communication.

After airbags or seatbelt pretensioners have deployed, a permanent record—known as crash data—is stored in the control unit’s internal memory. This lockout feature ensures safety by preventing further operation until the unit is professionally reset or replaced. Repairing the unit is often the more cost-effective alternative to purchasing a new one.

Besides accident-related failures, issues in the vehicle’s peripheral systems can also lead to malfunctions. Faulty or broken wiring, improper cabling of SRS components, or corroded and loose connectors disrupt signal pathways, resulting in error messages—even if the control unit itself remains intact. A thorough diagnosis is therefore essential.

How do you recognize a defect in 44323373?

A defective airbag control unit 44323373 primarily manifests as a permanently illuminated airbag warning light on the instrument cluster. Often, communication between the control unit and a diagnostic tool is also lost, preventing the reading of fault codes. Stored crash data is another clear indicator.

The most obvious symptom is the continuously lit SRS or airbag warning light. It fails to turn off after starting the vehicle, indicating a persistent, safety-critical fault within the system.

Another critical sign occurs when a specialized workshop cannot access the airbag control unit using a diagnostic scanner. This lack of communication points to a severe internal malfunction of the module.

If, following a traffic accident, a fault code related to stored crash data is read, this is not a typical defect but rather a manufacturer-imposed lockout requiring professional repair.
