3 Answers
The reasons for the anti-skid light illuminating in the Highlander include accidentally pressing the ESP off button, loose or faulty sensor connectors, short circuits or blown fuses in the wiring, software issues causing poor signal transmission, or a malfunction in the ABS pump. Below are some related introductions about the Highlander: 1. Overview of the Highlander: The Highlander is a Toyota-produced vehicle, a large SUV in the Toyota family.

I've encountered many Highlander owners asking about this issue. The most common reason for the anti-skid light to come on is problems with those small radars on the wheels. If the wheel speed sensor gets dirty, waterlogged, or covered with metal debris, the computer can't accurately receive wheel speed signals and will directly light up the warning light in protest. If the steering wheel's angle sensor is misaligned, it can also cause the system to misjudge the vehicle's posture. Also, many people don't realize that messed-up four-wheel alignment data can make the computer intervene excessively, causing the light to flash nonstop. Although rare, there have indeed been cases where the ABS fuse blew. Don't ignore these electronic system faults, especially when driving in rain or snow. If the vehicle stability function fails, it's easy to skid, so you should quickly plug in a diagnostic tool to read the trouble codes.
My Highlander also had the anti-skid warning light come on inexplicably last year. It suddenly started flashing while I was driving, which scared me into pulling over and restarting the vehicle to make it stop. Later, it turned out that the small black connector on the left front wheel had come loose, probably not secured properly after the last maintenance. The mechanic said the sensors are particularly sensitive to high-pressure water jets, as the connectors can oxidize when wet, leading to false alarms. Additionally, dust buildup on the steering gear position sensor can also trigger false warnings. A car wash attendant taught me a trick: disconnect the negative battery terminal for five minutes after turning off the engine to reset the onboard computer and clear temporary false alarms. If the light keeps coming on repeatedly, it's likely the sensor is failing, and replacing it with an original part costs around three to five hundred yuan.
