Where is the TRC OFF switch located in a Toyota?

[OAlice]

Toyota's TRC OFF switch is located below the steering wheel on the left side, near the headlight switch. TRC OFF stands for Traction Control System Off. The traction control system ensures that the vehicle obtains appropriate traction under various driving conditions, thereby preventing wheel slip. Traction Control System Principle: The traction control system is controlled by a computer that monitors the speed of all four wheels and the steering wheel angle. When accelerating, if the computer detects a significant difference in speed between the driven and non-driven wheels, it immediately determines that the driving force is excessive and sends a signal to reduce the engine's fuel supply, thereby decreasing the driving force and minimizing wheel slip. The computer also uses the steering angle sensor to understand the driver's intended steering direction and the wheel speed sensors to detect differences in speed between the left and right wheels. This helps determine whether the vehicle's turning behavior matches the driver's intentions. If understeer (or oversteer) is detected, the computer immediately reduces the driving force to align with the driver's steering input.
