Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Open Loop Control
The closed loop ratio control algorithm will not function correctly when the transmission is in a Neutral state. This is because the variable drive pulley speed signal is not valid in Neutral and actual speed ratio becomes an invalid signal. Additionally, when a malfunction is detected in either the input or output signal, actual speed ratio will not be a valid signal. When either of these situations occur, open loop control is used to maintain actual ratio and minimize the difference between actual and commanded ratio.
