What does the Buick TC slash yellow light mean?
4 Answers
Buick TC slash yellow light indicates that the traction control system is turned off. Here are the relevant details: 1. Traction Control System: The Buick Excelle TC slash yellow light means the traction control system is turned off, which happens when the OFF button on the center console is pressed. The traction control system controls the torque output of the engine to prevent the drive wheels from spinning on slippery surfaces like snow, ensuring smooth starting and acceleration. 2. Buick: The Buick Excelle is a compact 4-door, 5-seater sedan with dimensions of 4609mm in length, 1798mm in width, and 1486mm in height, a wheelbase of 2640mm, and a fuel tank capacity of 44 liters. It is equipped with a 1.37T turbocharged engine and a 6-speed automatic transmission, delivering a maximum power of 120 kW and a maximum torque of 230 Nm.
I've been driving a Buick for many years and have seen the yellow TC light with a slash come on several times. It indicates that the traction control system has been manually turned off or there may be a malfunction. Generally, this light comes on because you pressed a button in the car to turn off the TC function, such as intentionally disabling it when testing tires in the snow. But if it lights up automatically without any operation, you should be cautious about potential sensor or circuit issues in the vehicle. When this light is on, it means the car is more prone to skidding on slippery roads, especially during rain, snow, or sharp turns, increasing the risk of losing control. I recommend first trying to restart the vehicle to see if the light turns off. If not, check around the driver's seat for any accidental pressing of the TC switch. If the light remains on, it's essential to visit a 4S store or a professional repair shop to scan for fault codes with a computer, determining whether it's caused by a faulty module or aging wiring. Don't ignore this small light, and during regular maintenance, also pay attention to cleaning the vehicle's undercarriage sensors to prevent dust accumulation.
That time when I was driving my Buick on the highway, suddenly a yellow symbol with a slash and 'TC' appeared on the dashboard, which really freaked me out. After checking, I realized it was the Traction Control light coming on, meaning the system was either manually turned off or had a malfunction. Usually, it's fine if you turn it off with the button, but if it lights up automatically, it might be because the car's sensors are dirty or blocked by ice. With this light on, the car's grip is weaker, like wheels might spin and slip when accelerating on sandy roads, especially making new drivers more prone to panic. I found that just finding a safe place to park, turning off the engine, waiting a few minutes, and then restarting often makes the light go away; if not, taking a photo with my phone and asking for advice in the car owners' group helps. If it persists, it's necessary to check if the anti-slip module is water-damaged, rusted, or if a fuse is blown. Don't keep driving long distances with the light on—safety first. Developing a habit of regularly checking the dashboard lights is better than regretting it later.
If that yellow slash TC light on the dashboard comes on, it's most likely an issue with the traction control system—either it's been manually turned off or it's malfunctioning. This can significantly impact driving, making the car more prone to skidding on wet roads and less stable when taking turns. As someone who frequently drives on urban and rural roads, my first move when I see the light on is to pull over safely—no pushing the speed. Check if the TC switch inside the car was accidentally pressed and try resetting the system; if the light stays on, get it repaired promptly to avoid worsening sensor shorts or electrical faults. Protecting the safety of yourself and your family is paramount—don't skip inspections to save time.
