Airbag control unit with part number 150300-2193

What is the function of Airbag Control Unit 150300-2193?

The Airbag Control Unit 150300-2193 from supplier Autoliv is the central control unit for the occupant protection system in the Toyota iQ KGJ10 (2008–2015). It analyzes data from impact sensors and, within milliseconds, decides whether to deploy airbags and seatbelt pretensioners, providing optimal protection for occupants in the event of a crash.

As the most critical safety component in the vehicle, this control unit is responsible for monitoring and managing the entire restraint system. It continuously processes information from various sensors to remain prepared for a potential collision at all times.

The OEM part number 150300-2193 ensures exact electronic and mechanical compatibility with the Toyota iQ. To guarantee proper functionality, the unit is typically installed in a protected location inside the vehicle, usually in the center tunnel near the gearshift lever.

Why does the Control Unit 150300-2193 need repair?

The most common reason for repairing Control Unit 150300-2193 is the storage of crash data after an accident. This data permanently disables the unit’s functionality and cannot be erased using standard workshop diagnostic tools. Professional data clearing is therefore essential to restore full operational capability.

Once airbags or seatbelt pretensioners have deployed, the control unit writes an irreversible fault entry into its internal memory. This safety measure prevents reinstallation of a deployed unit without professional inspection and ensures that the airbag warning light remains illuminated.

Another scenario involves using a used control unit from a donor vehicle. In such cases, the unit must be professionally decoupled from the donor vehicle and reset before it can be reprogrammed for installation in the recipient vehicle. All these procedures require specialized equipment and extensive expertise.

How do you recognize a defect in Control Unit 150300-2193?

A defect in Control Unit 150300-2193 primarily manifests as the airbag warning light remaining constantly illuminated on the instrument panel. Additionally, the fault code stored in the error memory—indicating saved crash data—cannot be cleared using conventional diagnostic tools.

The most noticeable symptom is the airbag warning lamp, which lights up immediately upon ignition and stays on throughout driving. This signals a serious malfunction in the safety system.

During a diagnostic check at a workshop, a fault code will appear indicating “Crash Data Stored” or “Control Unit Defective/Blocked.” Such errors cannot be reset through standard procedures, and the vehicle would fail the mandatory technical inspection with this active fault.

How is Control Unit 150300-2193 professionally repaired?

At Airbag24, Control Unit 150300-2193 undergoes a standardized repair process. Following an initial inspection, specialized equipment is used to completely and thoroughly erase all stored crash data. The unit’s functionality is then verified on a test bench. We provide 2 years' statutory liability for defects on all repairs performed.

Upon receipt at Airbag24, the control unit first undergoes a detailed diagnosis. Technicians review the internal fault logs to confirm there are no additional hardware damages.

The core of the repair is erasing crash data at the chip level. This process restores the control unit to its factory settings, ensuring full functionality once again. The procedure is carried out in a way that preserves the integrity of the device and its warranty.

Subsequently, extensive tests are conducted to simulate correct communication and operation of all system components. Only after successfully completing these tests is the unit approved for return shipment.
