DIAGNOSIS CODE SET CONDITIONS


While the engine is running, when the fluid temperature is 20°C or more, the engine coolant temperature is 40°C or more, the drive mode selector position is in other than 4L/4LLc, and the mode is in other than sport mode (1st/2nd/3rd), if a status is detected with which the gear ratio (1st/4th/5th) does not change according to the shift pattern due to the ON seizure of shift solenoid No.2 (2 drive cycle), code No.P0757 is set.
note When the ON seizure of shift solenoid No.2 is detected, the normal gear ratio cannot be obtained because the gear does not change as shown in the table when the gear is in 1st/4th/5th.
