TROUBLE DIAGNOSIS CVT-33 D E F G H I J K L M A B CVT Revision: 2006 August 2006 Murano TROUBLE DIAGNOSIS PFP:00004 DTC Inspection Priority Chart NCS0012V If some DTCs are displayed at the same time, perform inspections one by one based on the following priority Fail-safe NCS0012W The TCM has an electrical fail-safe mode. This mode makes it possible to operate even if there is an error in a FAIL-SAFE FUNCTION If any malfunction occurs in a sensor or solenoid, this function controls the CVT to make driving possible. Output Speed Sensor (Secondary Speed Sensor) The shift pattern is changed in accordance with throttle position when an unexpected signal is sent from the Input Speed Sensor (Primary Speed Sensor) The shift pattern is changed in accordance with throttle position and secondary speed (vehicle speed) when PNP Switch If an unexpected signal is sent from the PNP switch to the TCM, the transaxle is put in “D”. Manual Mode Switch If an unexpected signal is sent from the manual mode switch to the TCM, the transaxle is put in “D”. CVT Fluid Temperature Sensor If an unexpected signal is sent from the CVT fluid temperature sensor to the TCM, the gear ratio in use before Transmission Fluid Pressure Sensor A (Secondary Pressure Sensor) ● If an unexpected signal is sent from the transmission fluid pressure sensor A (secondary pressure sensor) ● If transmission fluid pressure sensor A (secondary pressure sensor) error signal is input to TCM, second- Pressure Control Solenoid A (Line Pressure Solenoid) If an unexpected signal is sent from the solenoid to the TCM, the pressure control solenoid A (line pressure Pressure Control Solenoid B (Secondary Pressure Solenoid) If an unexpected signal is sent from the solenoid to the TCM, the pressure control solenoid B (secondary pres- Torque Converter Clutch Solenoid If an unexpected signal is sent from the solenoid to the TCM, the torque converter clutch solenoid is turned Priority Detected items (DTC) 1 U1000 CAN communication line 2 Except above |
