2. Faulty Wheel Speed Sensors: The wheel speed sensors monitor the speed of each wheel and send the information to the ABS control module. If one or more wheel speed sensors are malfunctioning, the ABS system can become disabled and the warning lights will illuminate.
3. ABS Control Module Failure: In some cases, the ABS control module itself may be faulty. This can be due to electrical issues, water damage, or internal component failure. A faulty ABS control module can cause various problems, including the ABS warning lights staying on.
4. Faulty Brake Light Switch: A faulty brake light switch can also trigger the 'OFF Fail' and 'Anti-lock' lights. The brake light switch sends a signal to the ABS control module when the brake pedal is pressed. If the brake light switch is faulty, the ABS control module may not receive the signal, causing the warning lights to come on.
5. Electrical Issues: Electrical problems, such as loose connections, damaged wires, or a blown fuse, can also lead to the ABS warning lights staying on. Check all the electrical connections related to the ABS system and make sure that there are no loose or damaged wires.
If you are not comfortable troubleshooting and resolving the issue yourself, it is best to take your Jaguar to a qualified mechanic. They will be able to diagnose and fix the problem accurately.
