However, a persistent or recurring light demands immediate diagnosis to prevent long-term damage. Troubleshooting begins with retrieving the diagnostic trouble code (DTC) using an OBD-II scanner; codes like P0505 (TCS malfunction) or similar point to specific sensor or system faults. Inspecting components like wheel speed sensors, ABS modules, and wiring harnesses can pinpoint the root cause. Even if the light disappears, addressing the underlying problem ensures reliability and safety on the road.
