How to Fix the Fault Code of Buick Excelle on Uneven Road?
2 Answers
Buick Excelle's uneven road fault is caused by a problem with the vehicle's tilt sensor, which needs to be replaced at a repair shop. Here is an introduction to the relevant content: 1. Characteristics of the sensor: miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. It is the primary link in achieving automatic detection and automatic control. The existence and development of sensors enable objects to have senses such as touch, taste, and smell. 2. Classification: According to their basic sensing functions, they are divided into ten major categories, including thermal elements, photosensitive elements, gas-sensitive elements, force-sensitive elements, magnetic-sensitive elements, humidity-sensitive elements, sound-sensitive elements, radiation-sensitive elements, color-sensitive elements, and taste-sensitive elements.
I've encountered the issue of the Buick Excelle throwing fault codes on uneven roads. In most cases, it's the wheel speed sensor acting up. That thing is installed near the wheel, and heavy bumps can easily cause poor contact or get it blocked by mud. If the fault code is related to ABS or traction control, nine times out of ten, it's the sensor. You'd better start by using a diagnostic tool to read the specific fault code and identify which wheel is affected. Then, remove it yourself to clean the connector. If that doesn't work, just replace it—it only costs a little over a hundred bucks. Also, check the chassis, especially the lower control arm ball joints and stabilizer bar bushings. Older Excelle models tend to loosen up over time, causing creaking noises over bumps, which can also trigger fault codes. If these parts are fine, then check for wiring wear or ECU issues. Don't rush into repairs—identify the problem first before taking action.
