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. Operate the vehicle in drive range and ensure TCC is commanded ON for 1 minute. Verify with a scan tool the following test status



parameters display OK:



* TCC Pressure Control Solenoid Valve Performance Test Status



* TCC Pressure Control Solenoid Valve Control Circuit High Voltage Test Status



* TCC Pressure Control Solenoid Valve 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/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:



* TCC Pressure Control Solenoid Valve Performance Test Status



* TCC Pressure Control Solenoid Valve Control Circuit High Voltage Test Status



* TCC Pressure Control Solenoid Valve 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/Service Fast Learn Adapts) following all transmission related repairs.



* Control Module References (See: Testing and Inspection/Programming and Relearning) for control solenoid valve assembly replacement,
