DTC DETECTING CONDITION: Detected when two consecutive driving cycles with fault occur. TROUBLE SYMPTOM: • Engine speed increases abruptly, and can not accelerate. • Excessive slippage is felt. 1. ENGINE TYPE FB WIRING DIAGRAM: CVT control system CVT Control System > WIRING DIAGRAM
2. ENGINE TYPE EZ WIRING DIAGRAM: CVT control system CVT Control System > WIRING DIAGRAM
3. OUTLINE OF DIAGNOSIS (ENGINE TYPE FB) • Detect the malfunction of transmission forward/reverse clutch pressure solenoid and hydraulic circuit characteristics (stuck to low pressure side). • Judge as NG if the value calculated by “turbine speed − primary pulley speed” becomes the predetermined value or more, even though the forward/reverse clutch is engaged. 4. EXECUTION CONDITION (ENGINE TYPE FB)
5. DIAGNOSTIC METHOD (ENGINE TYPE FB) If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
Time Needed for Diagnosis: 5 seconds Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles. 6. OUTLINE OF DIAGNOSIS (ENGINE TYPE EZ) • Detect the malfunction of transmission forward/reverse clutch pressure solenoid and hydraulic circuit characteristics (stuck to low pressure side). • Judge as NG if the value calculated by “output speed − secondary pulley speed” becomes the predetermined value or more, even though the forward/reverse clutch is engaged. 7. EXECUTION CONDITION (ENGINE TYPE EZ)
8. DIAGNOSTIC METHOD (ENGINE TYPE EZ) If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
Time Needed for Diagnosis: 5 seconds Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles. |
