Illustration 4 g02319176
TCS wheel spin ratio vs. steering angle
Illustration 4 is an example of the steering angle versus the spin ratio.Note: Illustration 4 is only for explanation purposes and does not depict the actual TCS software map in the Brake ECM.When the front wheels are straight, the TCS is active when one rear wheel is spinning approximately 1.2 times as fast as the other (spin ratio). The TCS provides more traction when the truck is traveling straight.The TCS becomes active at a higher spin ratio as the steering angle increases during a turn. When the TCS is active, the spin ratio is locked in until the TCS is de-activated. For example, if a wheel starts slipping and the operator turns the wheel slightly, the spin ratio will hold at the lower value regardless of the steering wheel angle.

Cover for steering cylinder position sensor (28)
Illustration 5 and Illustration 6 show left rear wheel speed sensor (24) and right rear wheel speed sensor (25). The TCS monitors the drive wheels through four input speed signals: one at each drive axle, and two at the transmission output shaft.Transmission output speed sensors (27) monitor the ground speed of the machine and provide input signals to Brake ECM (1) through the CAT Data Link. The TCS uses transmission output speed sensors (27) in order to disable the TCS when ground speed is above 19.3 km/h (12 mph).Steering cylinder position sensor (28) is located inside the left side steering cylinder. The sensor connector for steering cylinder position sensor (28) can be accessed by removing the cover shown in Illustration 7. The cover is located on the head end of the left side steering cylinder.
