What causes the ABS warning light and brake light to illuminate in the Jeep Renegade?

The reasons for the ABS warning light and brake light illuminating in the Jeep Renegade are as follows: 1. ABS wheel speed sensor issue: The wheel speed sensor is located on the wheel and is easily contaminated by dirt or mud. If the sensor is covered with a large amount of dirt, it can affect the transmission of the speed signal. The ABS computer cannot interpret the speed signal and will trigger an alert. In this case, cleaning the dirt off the sensor and adjusting the gap between the sensor and the signal ring should resolve the issue. If the wheel speed sensor is damaged, it must be replaced. 2. Wiring connection fault: This is also a relatively common issue. Although all vehicles are equipped with ABS systems, the assembly quality and materials can vary due to different manufacturing processes. Loose connections in the wheel speed sensor wiring are frequent, so this should be checked thoroughly. Troubleshooting wiring can be a tedious task, so patience is required. It's best to inspect each connector, including the contact condition of relevant fuses and the grounding of the ground wires.
