Conditions for Setting the DTC

P06AC

• TCM detects a 20 - 50°C (36 - 90°F), or greater difference between the transmission fluid temperature and TCM power up temperature, which depends on the average of transmission fluid temperature, TCM substrate temperature, and TCM power up temperature.
• TCM detects an 8 - 10°C (14 - 18°F), or greater difference between the TCM substrate temperature and TCM power up temperature, which depends on the average of the transmission fluid temperature, TCM substrate temperature, and TCM power up temperature.
• Above conditions have to be met for 5 min within a 6 min period.

P06AD 

TCM power up temperature is -254°C (-425°F) or less for 1 min.

P06AE 

TCM power up temperature is 254°C (489°F) or greater for 1 min.
