TM-284 < ECU DIAGNOSIS > [CVT: RE0F10A] TCM 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”. 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) to the TCM, the secondary pressure feedback control is stopped and the offset value obtained before the non- • If transmission fluid pressure sensor A (secondary pressure sensor) error signal is input to TCM, secondary pressure feedback control stops, but line pressure is controlled normally. Pressure Control Solenoid A (Line Pressure Solenoid valve) 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 valve) If an unexpected signal is sent from the solenoid to the TCM, the pressure control solenoid B (secondary pres- Torque Converter Clutch Solenoid valve If an unexpected signal is sent from the solenoid to the TCM, the torque converter clutch solenoid valve is Step Motor If an unexpected signal is sent from the step motor to the TCM, the step motor coil phases “A” through “D” are CVT Lock-up Select Solenoid valve If an unexpected signal is sent from the solenoid to the TCM, the CVT lock-up select solenoid valve is turned TCM Power Supply (Memory Back-up) Transaxle assembly is protected by limiting the engine torque when the memory back-up power supply (for DTC Inspection Priority Chart INFOID:0000000003806490 If some DTCs are displayed at the same time, perform inspections one by one based on the following priority .
