ITM(InterActive Torque Management) system can detect the tire size fault by calculating each wheel speed, if the tire size equipped at the vehicle is 10% bigger than normal tire.
Wheel Speed Sensor senses vehicle speed and difference between front and rear wheel speed.
Opreation for getting Rotating Speeds of front/rear wheel can be got from deviding wheel speed sensor Rotating Speeds of front/rear by 2.
This code is set, if ITM-ECU detect tha the tire size is 10% bigger than normal tire by calculating each wheel speed.
When the failure is set there is no signal in the warning lamp, just ITM-ECU sets and stores this code.
