* Pressure Control Solenoid Valve 4 Performance Test Status

* Pressure Control Solenoid Valve 4 Control Circuit High Voltage Test Status

* Pressure Control Solenoid Valve 4 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:

* Pressure Control Solenoid Valve 4 Performance Test Status

* Pressure Control Solenoid Valve 4 Control Circuit High Voltage Test Status

* Pressure Control Solenoid Valve 4 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.

* Replace the control solenoid valve assembly. Refer to Control Module References (See: Testing and Inspection/Programming and

Relearning) for replacement, setup, and programming.
