What does TRC OFF mean when it appears on a Toyota vehicle?
1 Answers
The illumination of the TRC OFF light in a Corolla indicates that the vehicle's traction control system is currently turned off. Additional information: 1. Traction Control System: The full English name of the traction control system is Traction Control System, abbreviated as TCS. TRC is just an alternative name used by Toyota for the traction control system. Similarly, Mercedes-Benz calls it ASR, BMW refers to it as DTC, and Cadillac labels it as TCS, among others. Although the names differ, the principles are largely similar. 2. Functions of the TRC system in vehicles: (1) Prevents wheel spin when driving on slippery surfaces such as snow, ensuring smooth vehicle starting and acceleration; (2) Applies braking force to limit wheel spin when drive wheels slip, also enabling stable turning during acceleration; (3) Controls the risk of vehicle skidding when navigating steep slopes or rugged rocky terrains.
