Circuit/System Verification

1. Operate the vehicle in 2nd gear long enough to ensure at least a 3掳C (5掳F) rise in TCM temperature.

2. Place the gear selector in Reverse for 5 seconds and then idle the vehicle in Park for 5 seconds. Verify with a scan tool the following test

status parameters displays OK:

* Shift Solenoid Valve 1 Control Circuit High Voltage Test Status

* Shift Solenoid Valve 1 Control Circuit Open Test Status

* Shift Solenoid Valve 1 Control Circuit 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 Q8 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/6L45/6L50/6L80/6L90 - Automatic

Transmission/Control Solenoid Valve and Transmission Control Module Assembly Inspection).

3. Place the Q8 control solenoid valve assembly on a clean work surface near the transmission assembly.

4. Connect DT-47825-10 - jumper harness between the vehicle wire harness electrical connector, and the Q8 control solenoid valve assembly

electrical connector.

5. Ignition ON, verify with a scan tool the following test status parameters display OK:

* Shift Solenoid Valve 1 Control Circuit High Voltage Test Status

* Shift Solenoid Valve 1 Control Circuit Open Test Status

* Shift Solenoid Valve 1 Control Circuit Low Voltage Test Status

瀚慖f any test status parameter displays Fault or Malfunction, replace the Q8 control solenoid valve assembly.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and

Inspection/Programming and Relearning) following all transmission related repairs.

Circuit/System Verification



1. If there are any other transmission related DTCs set, diagnose those DTCs first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle (



See: Diagnostic Trouble Code Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle).



2. Engine idling in Park with parking brake applied, and drive wheels chocked.



3. Monitor the TFP Switch 1, TFP Switch 3, TFP Switch 4, and TFP Switch 5 parameters with a scan tool.



4. Place the gear select lever in Park, Reverse, and Neutral range. Verify the TFP Switch 1, TFP Switch 3, TFP Switch 4, and TFP Switch 5



parameter states are correct for each range. Refer to Transmission Fluid Pressure Switch Logic (See: Specifications/Mechanical



Specifications/Automatic Transmission/Transaxle/System Specifications/6T70/6T75 - Automatic Transmission/Transmission Fluid Pressure



Switch Logic).



5. Place the gear select lever in Drive range. Command the Shift Transmission with a scan tool through all forward ranges. Verify the TFP



Switch 1, TFP Switch 3, TFP Switch 4, and TFP Switch 5 parameter states are correct for each range. Refer to Transmission Fluid Pressure



Switch Logic (See: Specifications/Mechanical Specifications/Automatic Transmission/Transaxle/System Specifications/6T70/6T75 -



Automatic Transmission/Transmission Fluid Pressure Switch Logic).



6. 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



electrical connector.



5. Ignition ON, verify with a scan tool that the TFP Switch 1, TFP Switch 3, TFP Switch 4, and TFP Switch 5 parameters changes states when



gently pushing on each TFP switch with the eraser end of a pencil.



瀚慖f any TFP Switch parameter does not change states, replace the control solenoid valve assembly.



Repair Instructions



Note:



* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and



Inspection/Programming and Relearning) following all transmission related repairs.



* Before replacing the TCM, 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
