What is a Skoda Karoq Mk1 airbag control unit?
The Skoda Karoq Mk1 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It processes information from sensors in real time, decides whether to deploy airbags and seatbelt pretensioners, and stores important crash data for diagnostics to ensure maximum safety.
This module, also called the SRS control unit, continuously monitors the vehicle occupants and the surroundings.
It is crucial for the smooth functioning of the passive safety system in your Skoda Karoq Mk1.
Why is the Skoda Karoq Mk1 airbag control unit defective?
The Skoda Karoq Mk1 airbag control unit can be defective due to internal memory errors, faulty self-tests, or power supply issues that impair its functionality. Such failures often result in an illuminated airbag warning light, making a professional Skoda Karoq Mk1 airbag control unit repair essential to restore vehicle safety.
Common causes are internal software or hardware errors that require repair or replacement.
Communication problems with other control units in the vehicle or loose connections can also cause the system to fail.
Common error codes for Skoda Karoq Mk1 airbag control unit repair
During a Skoda Karoq Mk1 airbag control unit repair, error codes are typically read out, indicating internal problems or communication disruptions. These codes, such as B1000 or B1100, signal memory errors, voltage deviations, or difficulties with the airbag control unit's internal self-test, which require a precise diagnosis.
These codes are specific to the airbag control unit and help identify the problem.
Diagnosis is best carried out using VAG-specific tools in the workshop.
- B1000 → Control unit communication error → Interruption of the data connection to the airbag control unit.
- B1100 → Internal memory error → Problem in the data memory of the airbag control unit.
- B1210 → Power supply or circuit fault → Insufficient or unstable power supply to the airbag control unit.
- B1011 → Internal self-test error → The airbag control unit failed an internal function test.
- B1160 → Flash ROM Error → Problem in the non-volatile memory of the airbag control unit.
- B1046 → EEPROM Error → Error in the electronic, erasable programming ROM of the airbag control unit.
- B1404 → Communication error between airbag control unit and other control units → Malfunction in the CAN bus network.
- B1423 → Control unit reset or reinitialization error → Unintentional restart or initialization problem of the airbag control unit.
What part numbers are available for the Skoda Karoq Mk1 airbag control unit repair?
For Skoda Karoq Mk1 airbag control unit repairs, exact OEM part numbers are crucial, but their precise verification requires professional databases. Common numbers, such as "5Q0 959 655 E" (VW/Skoda) or "1K0 959 655 G" (Bosch), serve as examples of similar systems, but are not specifically confirmed for the Skoda Karoq Mk1 and should be verified before any repair.
The exact part number for your Skoda Karoq Mk1 airbag control unit depends on the specific equipment and year of manufacture.
It is strongly recommended to determine the part number using the chassis number (VIN) via official Skoda catalogs (ETKA) or professional databases such as TecDoc.
