Circuit/System Verification
1. Ignition ON, clear the DTCs with a scan tool.
2. Operate the vehicle at 64 km/h (40 mph) for 10 minutes. Monitor the TCM Power-Up Temperature parameter and the TCM Temperature
parameter with a scan tool. The TCM Power-Up Temperature parameter and the TCM Temperature parameter should be within 10掳C (18掳F)
of each other.
瀚慖f the TCM Power-Up Temperature parameter is not within the specified value 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.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
* Control solenoid valve assembly replacement. Refer to Control Module References (See: Testing and Inspection/Programming and
Relearning) for replacement, setup, and programming.
* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and
Inspection/Programming and Relearning/Service Fast Learn Adapts) following all transmission related repairs.
