Manufacturer summary
Original wording in English
Some customers may see the A/T warning light on during (or immediately after) engine start-up with DTCs P073D:00-TCM / P1738:00-TCM stored. P073D:00-TCM: Turbine/input shaft speed sensor: Sensor output range malfunction P1738:00-TCM: Automatic transaxle internal malfunction This concern is caused by improper TCM logic. To eliminate this concern, the TCM control software has been modified to change the DTC detection logic, preventing DTC judgment during start-up.
