The ABS and parking brake lights on a 2002 Chevy Trailblazer may stay on due to a malfunction in the ABS system, such as a faulty wheel speed sensor, or issues with the brake fluid level or the parking brake itself. If the parking brake is not fully released, it can trigger the light as well. Additionally, a problem with the ABS module or wiring could also cause these warning lights to remain illuminated. It's advisable to have the vehicle diagnosed using an OBD-II scanner for accurate troubleshooting.
