Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Set Condition
DTC will set when the transmission temperature does not reach a normal operating temperature within a given time frame. Time is variable due to ambient temperature. Approximate DTC set time is 10 to 35 minutes.
The following are starting temperature to warm up times to set this DTC:
- Starting temperature -40° C (-40° F) warm up time 35 minutes.
- Starting temperature -28° C (-20° F) 25 minutes.
- Starting temperature -6.6° C (20° F) 20 minutes.
- Starting temperature 15.5° C (60° F) 10 minutes.
When the fault is set, calculated temperature is substituted for measured temperature, however the DTC is stored only after three consecutive occurrences.
