What is a Hyundai Porter H100 airbag control unit?
The Hyundai Porter H100 airbag control unit is the central safety unit that precisely controls the deployment of all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of a collision. It continuously monitors important sensors, stores relevant crash data in the EEPROM, and ensures the proper functioning of the entire safety system in your vehicle.
This sophisticated electronic component is responsible for monitoring and activating the airbags in the event of an accident.
It contains a microcontroller unit (MCU) with non-volatile memory in which both the vehicle and accident history are reliably stored.
Why is the Hyundai Porter H100 airbag control unit defective?
A Hyundai Porter H100 airbag control unit often malfunctions because crash data is permanently stored in the internal memory after an accident, preventing it from being deployed again. Internal memory errors, software failures, or power supply problems can also cause the system to report a malfunction, necessitating a "Hyundai Porter H100 airbag control unit repair."
The most common reason for failure is the storage of crash data after an accident, which blocks the module.
This data must be erased through special reprogramming in order to make the control unit operational again.
Other causes may be internal memory errors such as B1001 or B1003, which require reprogramming, or a software error (B1002) that disables the airbag system.
Sometimes a problem with the power supply (B1010) or the internal monitoring system (watchdog error B1020) is the reason why the control unit appears to be broken.
In these cases, a professional diagnosis helps to determine the exact cause and initiate a quick Hyundai Porter H100 airbag control unit repair.
Common error codes for Hyundai Porter H100 airbag control unit repair
When a Hyundai Porter H100 airbag control unit repair is necessary, specific B-codes will occur that directly indicate internal problems with the control unit and do not affect sensors or seatbelt pretensioners. These codes often signal memory or communication errors and require a targeted diagnosis of the module itself to correct the error and reactivate the system.
- B1000 → Control unit communication error → Error in the data bus communication of the airbag control unit.
- B1001 → Internal memory error in the airbag control unit → Damage or error in the non-volatile memory (EEPROM) of the module.
- B1002 → Airbag control unit software error → Problem with the internal software or firmware of the control unit.
- B1003 → Airbag control unit memory overflow → Too much or invalid data in the module memory.
- B1004 → Internal air mass storage malfunction → Internal error in the control unit's measuring and storage system.
- B1005 → Airbag control unit self-test error → The module cannot correctly check its own functionality.
- B1010 → Airbag control unit - power supply error → Problems with the electrical supply or internal voltage converters of the control unit.
- B1020 → Airbag control unit - watchdog error → The module's internal monitoring system reports a malfunction.
- B1030 → Data bus communication protocol error → Incompatibility or malfunction in communication via the vehicle data bus.
What part numbers are available for the Hyundai Porter H100 airbag control unit repair?
For Hyundai Porter H100 airbag control unit repairs, specific OEM part numbers are relevant to ensure exact compatibility and are essential for correct diagnosis and repair. The primary OEM number is SA3107500-00, supplemented by the Bosch supplier numbers 0285010 and 02595320, which refer to the original part and must be verified during repair.
The only 100% verified OEM part number for the Hyundai Porter H100 airbag control unit is SA3107500-00, often listed in conjunction with Delphi or Bosch.
This number uniquely identifies the original part as an airbag ECU for the specified vehicle model.
Additionally, two Bosch supplier numbers, 0285010 and 02595320, are known to be matching OEM identifiers typically used for airbag control units.
It is important to note these specific numbers during any Hyundai Porter H100 airbag control unit repair to ensure correct module identification and compatibility.
