How to solve the Geely ESC system malfunction?

When the ESC warning light comes on during driving, first pull over to the side of the road and then turn off the engine. Locate the pedal brake switch and check if it's loose. If it is, secure it properly, then restart the vehicle. This should clear the ESC warning light.
I've been driving a Geely for almost ten years and have also been troubled by the ESC warning light coming on. That time, it suddenly alarmed while I was taking a turn on a rainy day. I immediately slowed down and pulled over, not daring to drive too fast. Such issues shouldn't be delayed, so I quickly drove to the 4S shop for a check. The mechanic said the wheel speed sensor was covered in mud, affecting the signal. They cleaned it and performed a system reset, which fixed the problem. When driving, it's important to avoid deep puddles, and during regular car washes, don't forget to rinse the wheel hub area—dirty sensors are the most common cause of this issue. If the warning light stays on, never attempt to dismantle parts yourself; the electronic systems are quite complex, and mishandling could cause the brake assist function to fail as well.
Last week, my neighbor's ESC warning light suddenly came on, and he rushed to me in a panic for advice. I suggested he first try restarting the vehicle, as temporary signal interference can sometimes resolve it. If that didn't work, I told him to check if the tire pressures of all four wheels were balanced, as significant differences can cause the system to misjudge. Then, pop the hood to inspect the wiring harness connectors for any signs of rodent damage, which is quite common on rural dirt roads. The worst-case scenario would be a faulty control module, which would require connecting to a computer to accurately diagnose the trouble codes. I warned him to drive extra carefully if the light stays on, avoiding sharp turns or sudden braking, since this system manages anti-skid control. I reminded him that Geely's after-sales service network is actually quite convenient, and booking a direct inspection would be both hassle-free and safe.
A friend driving a Boyue had the ESC alarm go off during a long trip, which scared him into pulling over at a service area immediately. I guided him through three steps via WeChat: first, turn off the engine and wait five minutes before restarting to check if it was a false alarm; then, get out and inspect the wheels to see if anything like a plastic bag was tangled around the sensor; finally, drive slowly to the nearest repair shop. This system heavily relies on tire and brake data, with wheel speed sensor or wiring connection issues accounting for 90% of the faults. Last time I dealt with a similar situation myself, I found that oxidation on the tire sensor plug caused poor contact. Actually, replacing a new sensor at a 4S shop takes just half an hour and costs around three to four hundred yuan, which is much safer than risking driving with a fault.
