How to reset the ABS warning light on Roewe RX5?

[LePaul]

Once the warning light comes on, there are two methods to reset it. One is to visit a repair shop and have it cleared with a computer. The other method can be done by yourself by locating the car's battery. After a few minutes, reconnect it, and the ABS warning light will turn off.

That day when I was driving, I panicked a bit when the ABS light popped up on the Roewe RX5 dashboard. Remember to first find a safe place to stop, turn off the engine, wait a few minutes, and then restart—sometimes it's just the electronic system acting up. If the light stays on, you need to take it seriously. The most common issue is the wheel speed sensor being clogged with mud. Just use a water hose to rinse the black sensors on the inner side of all four wheels, but avoid using too strong a water flow. It’s also easy to check the ABS fuse in the fuse box yourself to see if it’s blown. However, never push through and keep driving. Last year, my neighbor kept driving on the highway with the ABS light on, and when he had to brake suddenly, the car skidded and hit the guardrail. The mechanic at the dealership told me that if this issue isn’t fixed, the wheels could lock up every time you brake, increasing the braking distance by over ten meters compared to normal. If you can’t figure out the cause, drive straight to the 4S shop to read the fault codes—their equipment will quickly tell whether it’s a sensor failure or a hydraulic pump problem. The repair isn’t expensive, but safety is priceless.

I've encountered the ABS light issue on my Roewe RX5 twice. The first time was after driving in the rain - mud and water on the wheel speed sensor caused a false alarm. I pulled over and wiped the small probe on the inner side of the wheel with a wet towel, which fixed it. The second time was more troublesome - an OBD scanner detected complete failure of the left front wheel sensor. The repair shop said it might be due to rodents chewing the wires or connector corrosion. I recommend everyone pay attention to the dashboard while driving. When the ABS light comes on, it means the anti-lock braking system isn't working, making braking much more prone to skidding. During rainy seasons, remember to check the cleanliness of wheel speed sensors monthly - those small black cubes hidden near the brake discs collect dust easily. If restarting doesn't help, go to a professional auto repair shop. They can locate the fault in minutes using diagnostic computers, and replacing a sensor only costs about 200 yuan. Never cheap out with aftermarket parts - only OEM parts provide proper matching stability.

The year I just got my Roewe RX5, the ABS light suddenly came on. I first checked three things myself: crawled under the car to see if the ABS wiring harness was scraped off; opened the engine compartment to confirm if the brake fluid level was too low; checked if there was abnormal tire wear. It turned out that the left rear wheel sensor connector was loose, and the fault light went out after unplugging and re-plugging it tightly. It is recommended that car owners prepare a set of simple detection tools. An ABS code eraser can be bought for thirty yuan on Taobao. If you go to a repair shop, remember to ask them to test whether the four-wheel speed data is synchronized. If not synchronized, it could be either a dirty sensor or a broken bearing magnetic ring. However, RX5 models after 2018 often have sensor corrosion problems, which is a design defect. It's best to let the 4S store do waterproof treatment.
