What is a Hyundai Aura AI3 airbag control unit?
The Hyundai Aura AI3 airbag control unit is the central safety unit in the vehicle, precisely activating all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors and stores relevant crash data, ensuring the proper functioning of all critical safety modules in the Hyundai Aura AI3.
This specialized electronic control unit acts as the brain of the passive safety system. It receives data from impact and acceleration sensors throughout the vehicle.
Its main task is to decide in a fraction of a second which airbags and belt tensioners need to be deployed in the event of an impact in order to optimally protect the occupants.
Why is the Hyundai Aura AI3 airbag control unit defective?
The Hyundai Aura AI3 airbag control unit often becomes defective due to stored crash data after an accident, internal electronic faults, or wiring problems, which can lead to airbag system failure. Timely diagnostics at the workshop are crucial to correcting such errors and restoring safety.
An airbag control unit is often classified as "defective" after an accident because it stores permanent crash data. This data must be erased by a professional Hyundai Aura AI3 airbag control unit repair before the system can be fully functional again.
Another reason for failure can be electrical problems, such as excessive resistance in the circuit or a short circuit to ground, which cause direct error codes in the control unit.
Aging or moisture can also damage internal components of the control unit and lead to unreliable behavior or a complete failure of the airbag function.
Common error codes for Hyundai Aura AI3 airbag control unit repair
When diagnosing a faulty Hyundai Aura AI3 airbag control unit, specific error codes are read, providing precise clues as to the nature of the problem. These codes are crucial for a targeted Hyundai Aura AI3 airbag control unit repair, as they indicate whether the problem is in the circuit or the control unit itself.
- B134600 → Driver airbag resistance too high (1st stage) → The cause is usually an open circuit in the circuit to the driver airbag, often due to a defective clock spring.
- B134800 → Driver airbag level 1 short circuit to ground → Cause is direct contact of the airbag line with the vehicle ground.
- B1346 → Driver airbag resistance too high (1st and 2nd stage) → Cause indicates a general problem with the resistance in the driver airbag circuit.
- B1620 → Crash data stored → The cause is an accident event data record permanently stored in the control unit, which can only be deleted by specialized repair software.
What part numbers are available for the Hyundai Aura AI3 airbag control unit repair?
There are no universally confirmed OEM part numbers for the Hyundai Aura AI3 airbag control unit available from available public search results, as this information is often only available through official manufacturer catalogs. Precise identification is best achieved using your Hyundai Aura's vehicle identification number (VIN) to determine the exact part number for a Hyundai Aura AI3 airbag control unit repair.
Major suppliers such as Bosch, Continental and Autoliv manufacture airbag control units, but the specific OEM numbers for the Hyundai Aura AI3 model are rarely publicly listed.
The exact part number is crucial to ensure that the Hyundai Aura AI3 airbag control unit repair performed matches your vehicle's system specifications.
We therefore strongly recommend consulting official Hyundai dealers or specialized databases such as TecDoc to obtain the exact part number, especially when it comes to a safety-relevant component.
Technical specifications and compatibility of the Hyundai Aura AI3 airbag control unit
The Hyundai Aura AI3 airbag control unit is specifically designed for comprehensive control of the airbag and seatbelt pretensioner systems in the Hyundai Aura from model year 2023. It supports up to six airbags and is fully integrated into the vehicle network via the CAN bus to ensure maximum occupant safety.
It continuously processes data from various sensors, including impact, seat occupancy and seat belt buckle sensors.
The control unit precisely controls the activation of the gas generators for the driver, front passenger, side and head airbags as well as the belt tensioners.
Compatibility exists with all Hyundai Aura variants from the specified model year, regardless of the engine type (petrol, CNG, turbo diesel), provided they are equipped with the AI3 airbag system generation.
Installation position and advantages of the Hyundai Aura AI3 airbag control unit repair
The Hyundai Aura AI3 airbag control unit is typically located centrally in the passenger compartment under the dashboard or in the center tunnel to provide optimal protection. A professional Hyundai Aura AI3 airbag control unit repair is a cost-effective alternative to a complete replacement, especially if only crash data needs to be erased or minor errors can be corrected.
The installation position ensures protection against vibrations and moisture and allows access to the important multi-pin connectors for sensors and the CAN bus.
The repairability of the AI3 model significantly reduces costs compared to purchasing a new control unit and is a sustainable solution.
After a successful Hyundai Aura AI3 airbag control unit repair, all stored error codes are erased and the system is restored to operational status, including misfire protection.
