If communication with the scan tool is not possible, the cause is probably a defective diagnostic trouble lineor the TCM is not functioning.

Starting is not possible when the selector lever is in P or N range. In such cases, the cause is probably a defectiveengine, torque converter or oil pump.

If the vehicle does cannot move forward when the selector lever is shifted from N to D or L range while the engine is idling, the cause is probably abnormal line pressure or a malfunction ofthe underdrive clutch or valve body.

If the vehicle does not reverse when the selector lever is shifted from N to R range while the engine is idling, the cause is probably abnormal pressure in the reverse clutch or low reverse brake or a malfunction of the reverse clutch, low reverse brake or valve body.

If the vehicle does not move forward or reverse when the selector lever is shifted to any position while the engine is idling, the cause is probably abnormal line pressure, or a malfunctionof the power train, oil pump or valve body.

If the engine stalls when the selector lever is shifted from N to D or R range while the engine is idling, the cause is probably a malfunction of the engine, torque converter clutch soledoid,valve body or torque converter (torque converter clutch malfunction).

If abnormal shocks or a time lag of 2 second or more occurs when the selector lever is shifted from N to D range while the engine is idling, the cause is probably abnormal underdrive clutch pressure or a malfunction of the underdrive clutch, valve body or closed throttleposition switch.

If abnormal shock or a time lag of 2 seconds or more occurs when the selector lever is shifted from N to R range while the engine is idling, the cause is probably abnormal reverse clutch pressure or low and reverse brake pressure, or a malfunction or the reverseclutch, low and reverse brake, valve body.

If abnormal shock or a time lag of 2 seconds or more occurs when the selector lever is shifted from N to D, N to R range while the engine is idling, the cause is probably abnormal linepressure or a malfunction of the oil pump or valve body.

If shocks occur when driving due to upshifting or downshifting and the transaxle speed becomes higher than the engine speed, the cause is probably abnormal line pressure or a malfunctionof a solenoid valve, oil pump, valve body or of a brake or clutch.

If all shift points are changed while driving, the cause is probably a malfunction of the output shaft speed sensor,TPS or a solenoid valve.

If some of the shift points are changed while driving, the cause is probably a malfunction of the valve body, or itis related to adaptive logic control and is not an abnormality.

If shifting does not occur while driving and no diagnostic trouble codes are given, the cause is probably a malfunctionof the Park/Neutral switch, or the TCM.

If acceleration is poor even if downshifting occurs while driving, the cause is probably a malfunction of the engine system,a brake or clutch, or the transaxle is in fail-safe.

If vibration occurs when driving at constant speed or when accelerating in top range, the cause is probably abnormal torque converter clutch pressure or a malfunction of the engine, torque converterclutch solenoid, torque converter or valve body.

If the TPS output voltage is 4.8 V or higher when the engine is idling, the output is judged to be too high and diagnostic trouble code P1704 is output.

If the oil temperature sensor output detects the voltage which corresponds to 200°C(392°F) or more for more than one second, it is judged that there is an open circuit in oil temperature sensor and diagnostic troublecode P0713, P0712 are output.

If no output pulse is detected from the crankshaft position sensor for 5 seconds or more while driving output shaft speed at 1000 rpm, it is judged that there is an open or short circuit in the engine rpm signal line and diagnostic trouble code P0725 is output.

If no output pulse is detected from the input shaft speed sensor for 1 second or more while driving in 3rd or 4th gear at a speed of 30 km/h (19 mph) or more, it is judged to be an open circuit or short-circuit in the input shaft speed sensor and diagnostic trouble code P0715 is output. If diagnostic trouble code P0715 is the output four times, the transaxle is locked into 3rd gear or 2nd gear as a fail-safe measure.

If the drive duty rate for the torque converter clutch solenoid is 100% for a continuous period of 4 seconds or more, it is judged that there is an abnormality in the torque converter clutch system and diagnostic trouble code P0740 is output. When diagnostic trouble code P0743 is output, the transaxle is locked into 3rd gear as a fail-safemeasure.

If the lock-up clutch remains engaged for a continuous period of 10 seconds when the TCM is attempting to disengage the lock-up clutch, it is judged that the torque converter clutch is stuck on and diagnostic troublecode P0740 is output.

If the output from the output shaft speed sensor multiplied by the 1st gear ratio is not the same as the output from the input shaft speed sensor after shifting to 1st gear has been completed, diagnostic trouble code P0731 is output.
