What does the yellow TC light on a Cadillac mean?
1 Answers
When the yellow TC light appears on a Cadillac, it indicates that the Traction Control System is turned off, and the engine is in the start-up state. Below is relevant information about the Traction Control System: 1. ESP System: The ESP system is essentially a type of Traction Control System. Compared to other traction control systems, ESP not only controls the drive wheels but also the non-drive wheels. For example, in rear-wheel-drive vehicles, oversteering often occurs, where the rear wheels lose control and cause the car to fishtail. In such cases, ESP will brake the outer front wheel to stabilize the vehicle. In cases of understeering, to correct the tracking direction, ESP will brake the inner rear wheel to adjust the driving direction. 2. Function: The ESP system is a crucial component in a vehicle, typically supporting the functions of ABS and ASR. By analyzing the vehicle's driving state information collected from various sensors, ESP sends correction commands to ABS and ASR to help maintain the vehicle's dynamic balance. ESP ensures optimal stability under various conditions, with particularly noticeable effects in cases of oversteering or understeering. The installation of ESP generally requires sensors such as steering sensors, wheel sensors, side-slip sensors, and lateral acceleration sensors.
