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 -59°C (-74°F) or less for 1 min.

P06AE 

TCM power up temperature is 164°C (327°F) or greater for 1 min.
