One of the most crucial safety features in your VW vehicle is the Supplemental Restraint System (SRS), more commonly known as the airbag system. It’s a complex network of sensors, modules, and airbags designed to protect you and your passengers in a collision. When a malfunction occurs within this system, your car’s onboard diagnostics system will store a specific SRS scan code. These codes are essential for mechanics as they pinpoint the exact location and nature of the problem. Understanding these codes can be helpful for VW owners as well, allowing you to better understand potential issues and communicate more effectively with your mechanic.

What Does the SRS Warning Light Mean?
The SRS warning light, often depicted as a seated figure with an airbag deployed in front of them, illuminates on your dashboard when the system’s control unit detects a fault. This could indicate an issue with the airbags themselves, the seat belt pretensioners, crash sensors, wiring, or the control module itself.
Ignoring this warning light is strongly discouraged, as a malfunctioning SRS system compromises your safety and that of your passengers in case of an accident.
Common VW Car Diagnostics SRS Scan Codes
Here are some of the most common SRS scan codes encountered in Volkswagen vehicles:
- B0001: Driver frontal airbag deployment control circuit open
- B0002: Driver frontal airbag deployment control circuit low resistance
- B0003: Passenger frontal airbag deployment control circuit open
- B0004: Passenger frontal airbag deployment control circuit low resistance
- B0012: Driver side airbag stage 1 deployment control circuit open
- B0014: Passenger side airbag stage 1 deployment control circuit open
- B0017: Driver seat belt pretensioner circuit high resistance
- B0018: Passenger seat belt pretensioner circuit high resistance
- B0022: Frontal crash sensor 1 circuit low input
- B0023: Frontal crash sensor 1 circuit high input
- B0100: Crash sensor power supply voltage out of range

“Understanding the specific codes allows VW owners to address concerns proactively and avoid potential safety hazards,” says John Miller, Senior Automotive Engineer at DiagFixPro. “It also empowers them to engage in more informed discussions with their mechanics.”
What Causes SRS Fault Codes?
A variety of factors can trigger SRS fault codes in your VW. Some common culprits include:
- Loose Wiring or Connections: Vibrations and wear and tear can loosen connections within the SRS system, triggering fault codes.
- Faulty Sensors: Crash sensors, seat occupancy sensors, and other sensors within the system can malfunction due to age, impact, or exposure to the elements.
- Damaged Clockspring: The clockspring, located within the steering wheel, allows for electrical connections while the steering wheel rotates. Damage to this component, often due to excessive turning, can disrupt airbag communication.
- Depleted Battery: A weak or depleted car battery can cause voltage fluctuations, potentially affecting the SRS control module.
- Aftermarket Modifications: Modifying your VW with aftermarket parts, especially those interfering with the airbag system, can lead to SRS faults.
How to Diagnose and Fix SRS Codes
Diagnosing SRS codes requires specialized equipment and knowledge. While understanding the codes can provide initial clues, it’s crucial to have a qualified mechanic equipped with a professional-grade OBD2 scanner diagnose and address any issues.
Attempting to tamper with or repair the SRS system yourself can be dangerous and is not recommended. The system deals with explosive components and requires careful handling by trained professionals.
