Set Conditions

is DTC will set when the desired 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 temp -40°C (-40°F) warm up time 35 minutes, starting temp -28°C ( -20°F) 25 min, starting temp -6.6°C (20°F) 20 minutes, starting temp 15.5°C (60°F) 10 minutes. When the fault is set, calculated temperature is substituted for measured temperature, however the fault code is stored only after three consecutive occurrences of the fault.
