2010 Cadillac Truck Escalade/ESV RWD V8-6.2L Page 2249
The TFT is 174掳C (345掳F) or greater for 10 seconds or more.
Action Taken When the DTC Sets
* DTCs P0711, P0712, and P0713 are Type C DTCs.
* The TCM freezes transmission adaptive functions.
* The TCM allows the vehicle to operate in transmission protection mode.
Conditions for Clearing the DTC
DTCs P0711, P0712, and P0713 are Type C DTCs.
Diagnostic Aids
During a road test, the transmission fluid temperature (TFT) should steadily increase to a normal operating temperature, and then stabilize.

(DTC) Type Definitions)
Circuit/System Verification
1. Engine idling at normal operating temperature, verify the scan tool Trans Fluid Temp. parameter is between -74 and +174掳C (-101 and +345掳
F).
瀚慖f not within the specified range, replace the Q8 control solenoid valve assembly.
2. Operate the vehicle at 64 km/h (40 mph) for 10 minutes. Monitor the Transmission Fluid Temperature parameter and the TCM Temperature
parameter with a scan tool. The Transmission Fluid Temperature parameter should increase by more than 2掳C (3.5掳F). Also, the
Transmission Fluid Temperature parameter and the TCM Temperature parameter should be within 10掳C (18掳F) of each other.
瀚慖f the Transmission Fluid Temperature parameter does not increase by more than 2掳C (3.5掳F) or the Transmission Fluid Temperature
parameter is not within 10掳C (18掳F) of the TCM Temperature parameter, then replace the Q8 control solenoid valve assembly.
3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the
conditions that you observed from the Freeze Frame/Failure Records data.
