Circuit/System Verification



1. Operate the vehicle in second gear long enough to ensure at least a 3掳C (5掳F) rise in TCM temperature, then operate the vehicle in Park for 5



seconds.



2. Operate the vehicle in drive range. Allow the transmission to shift through all forward gear ranges. Verify with a scan tool the following test



status parameters display OK:



* PC Sol. 3 Perf. Test Status



* PC Sol. 3 Ckt. High Voltage Test Status



* PC Sol. 3 Ckt. Low Voltage Test Status



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.



Circuit/System Testing



Note: You must perform the Circuit/System Verification first.



1. Ignition OFF, remove the control solenoid valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly



Replacement (See: Powertrain Management/Transmission Control Systems/Actuators and Solenoids - Transmission and



Drivetrain/Actuators and Solenoids - A/T/Shift Solenoid/Service and Repair).



2. Perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection (See: Transmission and Drivetrain/Automatic



Transmission/Transaxle/Testing and Inspection/Component Tests and General Diagnostics/6T70/6T75 - Automatic Transmission/Control



Solenoid Valve and Transmission Control Module Assembly Inspection).



3. Place the control solenoid valve assembly on a clean work surface near the transmission assembly.



4. Connect DT-47825-20 - jumper harness between the vehicle wire harness electrical connector, and the control solenoid valve assembly
