1. Sensor Triggered: Many modern vehicles are equipped with sensors in the wheels that monitor tire pressure and provide feedback to the onboard systems. Changing tires might impact these sensors or their wiring, causing them to malfunction or trigger false error codes, which could activate the SRS light.
2. Accidental Impact: When changing tires, it's possible to accidentally jolt or impact another component in the vehicle that might be related to the SRS. For example, bumping the steering column cover, instrument panel, or seat belt mechanisms could trigger the SRS light to turn on.
3. Battery Disconnection: Some tire changes require disconnecting the vehicle's battery to access the tire. Disconnecting and reconnecting the battery can cause a brief interruption of power to various electronic components, including the SRS system. If there are any issues or abnormalities during this process, the SRS light might come on.
4. Faulty Tire Pressure Monitoring System (TPMS): If your vehicle has TPMS sensors mounted within the wheels, a tire change can affect their positioning or functionality. If these sensors are not properly reset after the tire change, it can trigger a TPMS warning that may be accompanied by the activation of the SRS light.
5. Electrical Issues: Changing tires involves handling various wheel components and electrical connections, such as those for the tire pressure sensors or wheel speed sensors. If there's any damage or disturbance caused to these electrical connections during the tire change, it could lead to SRS system malfunctions and illuminate the SRS light.
If the SRS light comes on after a tire change, it's important to have it checked by a qualified mechanic or a dealership. They can accurately diagnose the cause of the problem and take the appropriate steps to rectify the issue and turn off the SRS light.
