What causes the Roewe anti-skid light to stay on?

[JesseLynn]

The reasons why the Roewe anti-skid light stays on are: 1. Accidentally pressing the ESP off button; 2. Loose or faulty sensor connectors; 3. Short circuit in the wiring or related fuse blown; 4. Software issues causing poor signal transmission; 5. ABS pump failure. A yellow P light indicates that there is a fault stored in the parking brake or ABS system, requiring further inspection and confirmation. Additional information: 1. The P light in the combination instrument panel: Generally represents the vehicle's parking brake system, i.e., the handbrake system. When the P light in the combination instrument panel is on, it can appear in three colors. The meaning varies slightly depending on the vehicle brand and the color of the P light. 2. A red P light: Indicates that the parking brake system is engaged, meaning the handbrake is pulled tight. It is displayed in red in the combination instrument panel as a normal status, not a fault. If it lights up or flashes along with other fault lights, such as the ABS system light, it indicates a system fault. 3. A green or blue P light: Indicates that the automatic parking, i.e., the AUTO-HOLD system, is functioning properly. The P light will illuminate to alert the driver when the system is active.

My Roewe has been running for five or six years, and last month the anti-skid light also came on. The technical name for this thing is the ESC system indicator light, which is like an electronic bodyguard to prevent skidding during turns. If the light stays on, definitely don’t force it to drive. When I encountered it, I first checked the tires and found that the left front tire pressure was 0.5 lower than the other three. After topping up the air, the light went off. If that doesn’t work, you’ll need to consider the sensors—the wheel speed sensor is the most prone to issues. Last time, it gave a false alarm after splashing mud in the rain. If all else fails, try rebooting the car’s system: turn off the engine, wait about ten minutes, and then restart. By the way, if you’ve modified the brakes or installed tires with mismatched sizes, that could also trigger it. It’s best to read the fault codes to pinpoint the problem.

It's common to see Roewe owners coming in to check this anti-skid light during car repairs. Most cases are caused by a dirty ABS sensor or an interrupted wheel speed sensor signal - even a pebble hitting the sensor connector can cause issues. Some situations involve uncalibrated steering angle sensors, like when tires are replaced without doing a wheel alignment. The most troublesome case is a faulty ESP control module, which costs thousands to replace. I recommend first checking all four wheels for any stuck debris, then disconnecting the negative battery terminal for five minutes to reset the system. If the light remains on, go to a professional shop immediately to check the trouble codes.

Once when I was driving my friend's Roewe on the highway, the small car skidding icon suddenly lit up and wouldn't turn off, which scared me into immediately pulling over at a service area. Later I learned this was the anti-skid system issuing a warning, with three common causes: first, bumpy roads causing sensor misjudgment; second, poor contact in the brake light switch triggering it indirectly; third, unstable system voltage. In my case, replacing the brake light switch fixed it. Normally, pay special attention to keeping tire tread depth differences within 2mm, otherwise the system will alert when it detects inconsistent grip.

A friend who's into car modifications told me that diagnosing this warning light requires distinguishing between cold and hot engine conditions. If it lights up during a cold start, it's mostly a sensor hardware issue. If it appears after driving for half an hour with a warmed-up engine, it could be a system overheating protection trigger. From my observation, a common cause for Roewe vehicles is dust accumulation on the ABS tone rings, especially in northern areas with heavy sandstorms. Another less common reason is battery aging - when voltage drops below 12V, it can cause electronic stability program malfunctions. For DIY troubleshooting, you can try cleaning the inner side of the wheel hubs, but for a complete solution, you'll need an OBD scanner to read the specific fault location.
