What causes the car ESP warning light to illuminate?

[StValeria]

If the indicator light on the dashboard is illuminated, it may indicate a system malfunction, typically related to sensor issues, and requires inspection at a 4S shop. If the indicator light on the button switch is illuminated, it is likely due to the system being turned off, and simply turning the switch back on should resolve the issue. There are several possible reasons for the car ESP warning light to illuminate: 1. Slippery road conditions: The road surface may indeed be slippery, causing the ABS to activate, which triggers the light. 2. ABS pump failure: A malfunction in the ABS pump can also cause the car ESP warning light to illuminate. 3. Signal transmission error: A false alarm from the vehicle's computer. If the light remains illuminated for an extended period, there is likely an issue that requires prompt repair. If the light turns off shortly after illuminating, the first possibility is more likely. An ABS issue is not an urgent repair requirement; the vehicle can still be driven normally, but the ABS functionality will be disabled.
