What is a Kia Cerato LD airbag control unit?
The Kia Cerato LD airbag control unit is the central safety unit that precisely activates all occupant restraint systems, including the airbags, in the event of a collision. It continuously monitors sensors, stores relevant crash and diagnostic data, and is essential for a professional Kia Cerato LD airbag control unit repair.
This specialized electronic module, often referred to as the SRS (Supplemental Restraint System) module, is responsible for controlling airbag deployment.
It processes signals from impact sensors and other safety systems in milliseconds in order to specifically fire airbags such as driver, passenger or side airbags in an emergency.
The control unit is also equipped with an internal memory that records all faults in the system and makes them available for later diagnosis.
Why is the Kia Cerato LD airbag control unit defective?
A Kia Cerato LD airbag control unit often becomes defective because it stores crash data after an accident that requires a reset or replacement, or because internal components are damaged due to aging, moisture, or overvoltage, making immediate Kia Cerato LD airbag control unit repair unavoidable.
The most common cause of failure is the storage of crash data after an airbag deployment, which locks the module for future deployments.
In addition, internal memory errors (EEPROM), software problems or disturbances in the power supply can lead to malfunctions of the control unit.
External influences such as water damage, corrosion or improper interventions can also damage the sensitive module and make diagnosis more difficult.
Common error codes for Kia Cerato LD airbag control unit repair
During a Kia Cerato LD airbag control unit repair, specific B error codes directly indicate problems with the airbag control unit itself and facilitate diagnosis by ruling out sensors or seatbelt pretensioners. Accurately reading these error codes is the first step toward a successful repair.
- B1000 → Control unit communication error → Error in the internal or external data transmission of the module.
- B1100 → Internal memory error in the airbag ECU → Defect in the EEPROM or flash memory of the control unit.
- B1200 → Airbag ECU software error → Damage or corruption of the control unit's internal software.
- B1400 → Airbag control unit power supply fault → Interruption or fluctuation in the voltage supply to the module.
- B1500 → Airbag ECU initialization error → The control unit cannot complete the start-up process correctly.
- B1600 → EEPROM error in the airbag control unit → Specific error in the non-volatile memory of the module that stores configuration data.
- B1700 → Diagnostic communication error with other control units → The airbag module cannot communicate correctly with other vehicle systems.
- B1800 → Airbag control unit temperature error → The module reports an internal overheating or a temperature sensor error.
What part numbers are available for Kia Cerato LD airbag control unit repair?
For Kia Cerato LD airbag control unit repairs, only specific OEM part numbers from the manufacturer Kia (Hyundai-Kia) are 100% verified. These numbers ensure proper fit and function and are crucial for the safety and reliability of the airbag system.
The exact original part numbers for the airbag control unit of the Kia Cerato LD (first generation) are: 95910-2F100, 95910-2F200 and 95910-22400.
There are no confirmed alternative supplier part numbers from manufacturers such as Bosch, Continental or Autoliv that would directly fit this specific model and year.
The compatibility of these modules extends to the Kia Cerato LD from around 2004, including variants with 1.6 and 2.0 liter petrol and 2.0 CRDi diesel engines, and is essential for a professional Kia Cerato LD airbag control unit repair.
