If the TC light stays on, it indicates that the Traction Control System is turned off. TC stands for Traction Control System, and in this case, simply turn the system back on. If the TC light is flashing, it means the Traction Control System is actively working. If the issue is not caused by accidentally turning off the switch, it may indicate a malfunction in the Traction Control System, requiring a visit to a repair shop for inspection. Possible reasons for the TC light illuminating in a Cadillac: It could be due to a fault in the intake or exhaust camshaft position sensor. If cleaning does not resolve the issue, replacement may be necessary. Another possibility is a fault in the wiring harness of one of the four wheels, which would require immediate replacement. To diagnose the issue, read the fault codes. The Traction Control System is a standard feature in almost every vehicle, crucial for driving stability and safety. This system only activates when the drive wheels slip. When slipping occurs, the system limits engine power output and applies braking to the slipping wheel, preventing further loss of traction and helping the tires regain better grip for smoother driving. Vehicles are equipped with many similar auxiliary systems, such as the Brake Force Distribution System, ESP Electronic Stability Program, ABS Anti-lock Braking System, etc. Without these systems, driving would be much more difficult and prone to loss of control. When these systems are active, corresponding indicators on the dashboard will flash. The ESP Electronic Stability Program can be turned off, and when deactivated, its dashboard indicator will remain lit. However, ABS and the Brake Force Distribution System cannot be turned off.

What Are the Causes of Severe Odors Inside the Car?

Severe odors inside the car are mainly caused by excessive formaldehyde, poor-quality sound insulation cotton, and issues with asphalt damping boards. The details are as follows: Excessive Formaldehyde: Due to the narrow space and good sealing of the car, there is insufficient ventilation, and the air inside the car is limited. Additionally, cross-contamination among passengers worsens the situation. Harmful gas levels in cars can be more hazardous to human health than those in indoor environments. The most common method to remove formaldehyde is by opening windows for ventilation, which is almost cost-free. Park the car in a sunny, open area where it won't disturb anyone, open all doors, and use sun exposure to eliminate the odor. Poor-Quality Sound Insulation Cotton: The primary function of sound insulation cotton is to block interior sounds, noise, and vibrations. Car owners can replace the sound insulation cotton to address this issue. Issues with Asphalt Damping Boards: Asphalt damping boards are used to reduce vibration and noise. However, they also have drawbacks, such as being heavy and having a limited applicable temperature range. Most of the toxic gases in vehicles are produced by these boards. Enhancing natural ventilation while driving is the most effective and economical method to mitigate this problem.

Will the Car Become Lighter After an Oil Change?

After an oil change, the car will not become lighter. However, when higher-quality oil is used, the improved lubrication effect may make the car feel more "agile" to the driver, creating an illusion that the car has become lighter. Below is detailed information about engine oil: 1. Overview: Engine oil, also known as engine lubricant (Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption in the engine. 2. Composition: Engine oil consists of base oil and additives. Base oil is the primary component of lubricants, determining their fundamental properties. Additives are used to compensate for and improve any deficiencies in the base oil's performance, as well as to impart new characteristics, making them an essential part of lubricants.
