What is the reason for the ABS and anti-skid yellow lights to come on?
3 Answers
The reasons for the ABS and anti-skid yellow lights to come on are as follows: Issues with the anti-skid system: For example, driving on icy or snowy roads can cause differences in braking between the front and rear wheels due to varying rotation speeds, especially when braking is applied. This may trigger the ABS light. In such cases, pressing the brake pedal several times can often turn off the ABS light. Damaged ABS sensor on the wheel: Check if the handbrake light is also on. If both the ABS and handbrake lights are illuminated, it may indicate a serious fault in the vehicle's braking system. In this situation, you should not continue driving. Immediately slow down, pull over to the side of the road, and contact a repair station for assistance.
When the ABS and anti-skid lights come on, as someone who often tinkers in the workshop, I think it's necessary to mention some common causes first. The wheel speed sensor is the most prone to issues—dirt or water damage can send false signals, causing the system to fail. Then there's the module itself malfunctioning, such as a faulty ABS computer leading to poor control. Loose or corroded wiring connectors are also common, especially after driving long distances in the rain. I've seen too many cases where small problems lead to big troubles, like ABS failure during emergency braking, making it harder to control tire skidding. It's advisable not to force driving—find an open area to test the brake response. If safety is a priority, directly contact a repair shop to check the fault codes with a diagnostic tool to avoid compromising driving safety. Replacing a sensor costs just a couple hundred bucks—don't wait until it's a major issue to fix it.
Back when I was into car modding, my buddies and I always wondered why these warning lights would come on. Misaligned or dirty wheel speed sensors are a major headache, especially after off-roading when mud buildup triggers false alerts. Then there's aged relay contacts or software glitches causing the system to light up warnings. If you're hands-on, start by checking if the wheel sensors are properly aligned, and use a smartphone OBD tool to scan for trouble codes to rule out temporary interference. When the traction control light comes on, it might affect cornering grip - downright dangerous on highways. Pro tip for system resets: try parking and turning off the engine for ten minutes to see if it clears, otherwise head to a pro shop for reprogramming. Regular undercarriage washes prevent sensor dust buildup - saves both money and hassle.
