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.

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 PC Sol. Perf. Test Status

* TCC PC Sol. Ctrl. Ckt. High Voltage Test Status

* TCC PC Sol. Ctrl. 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 the DT-47825-20 adapter harness between the vehicle wire harness electrical connector, and the control solenoid valve assembly

electrical connector.

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

* TCC PC Sol. Perf. Test Status

* TCC PC Sol. Ctrl. Ckt. High Voltage Test Status

* TCC PC Sol. Ctrl. Ckt. Low Voltage Test Status

瀚慖f any test status parameter displays Fault or Malfunction, 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

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

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