Why does just the VSC light stay on in a 2001 Lexus LS 430?

The VSC (Vehicle Stability Control) light staying on in a 2001 Lexus LS 430 typically indicates a malfunction in the stability control system. This could be due to issues such as a faulty wheel speed sensor, problems with the brake system, or low brake fluid levels. It's advisable to check for any trouble codes using an OBD-II scanner, as this can provide more specific information about the underlying issue. If the problem persists, consulting a qualified mechanic for a thorough diagnosis is recommended.
