Diagnosis conditions
- Engine speed: More than 600 rpm
- Primary pulley speed: More than 450 rpm
- Idle is not being detected.
- Acceleration/deceleration speed: -0.49 m/s ² (-0.05 G) or more
- The primary pulley speed experienced 300 rpm or more and the secondary pulley speed experienced 250 rpm or more at least once.
- Secondary pulley speed: More than 150 rpm
- TCM power supply voltage: More than 11 V
Detection condition A
- Status with the shifting ratio of the primary pulley speed/secondary pulley ratio exceeding 2.825 is 0.2 sec or more continuously.
Detection condition B
- Status with the shifting ratio of the primary pulley speed/secondary pulley ratio exceeding 3.625 is 0.1 sec or more continuously.
