What causes the ABS warning light to illuminate and the steering wheel to become heavier in a Range Rover Evoque?
1 Answers
The reasons for the ABS warning light illuminating and the steering wheel becoming heavier in a Range Rover Evoque include: the ABS speed sensor's sensing part being covered; poor signal transmission due to loose connections between system wiring or poor contact in the ABS relay, leading to system malfunction. The reason for the heavy steering wheel in a Range Rover Evoque is often due to a leak in the power steering pump's oil pipe or a lack of oil in the reservoir, causing the booster pump to fail and resulting in heavy steering. The solution is to check whether the power steering pump has oil pressure or if there is a fault in the oil line. If the ABS speed sensor's sensing part is covered by dirt, mud, or other contaminants, it can affect the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle's speed and the wheel's slip rate, making it unable to issue appropriate commands to adjust braking. The solution is to clean the dirt off the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Poor signal transmission due to loose connections between system wiring or poor contact in the ABS relay can lead to system malfunction. The most common issue is a loose speed sensor wire connector, which can cause the ABS computer's fault memory to display a poor speed sensor signal. The solution is to inspect the wiring connections and reattach any loose parts.
