4-speed Automatic Transmission

Scan Tool Data Definitions

Gear Position (1ST, 2ND, 3RD, 4TH, 5TH, N, R) This parameter is indicated actual gear position.
Throttle Position (%) It indicates throttle valve opening ratio sent from ECM through CAN communication line.
Input Shaft Rev (RPM) It indicates input shaft revolution computed by reference pulses coming from input shaft speed sensor on transmission case.
Output Shaft Rev (RPM) It indicates output shaft revolution computed by reference pulses coming from output shaft speed sensor on transmission case.
Vehicle Speed (Km/h) This parameter is computed by output shaft speed sensor and 4L/N switch (if equipped) on TCM. Gear shift schedule relate this parameter.
Battery Voltage (V) It indicates battery voltage read by TCM as analog input signal by TCM.
ATF Temperature (°C) It indicates ATF temperature detected by signal from transmission fluid temperature sensor installed in valve body.
Accel Actual Position (%) It indicates accelerator pedal opening ratio detected by signal through CAN communication line fed from ECM.
Pressure Control Sol (%) Electric current value ratio between electric current value being outputted from TCM to pressure control solenoid-A and maximum value can be outputted by TCM.
Slip RPM (RPM) This parameter indicates slipping rotation in the torque converter (difference between input shaft rotation and engine rotation)
Engine Speed (RPM) It indicates engine speed computed by signal through CAN communication line fed from ECM.
ECT (°C) It indicates engine coolant temperature detected by signal through CAN communication line fed from ECM.
