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:
* Pressure Control Solenoid Valve 2 Performance Test Status
* Pressure Control Solenoid Valve 2 Control Circuit High Voltage Test Status
* Pressure Control Solenoid Valve 2 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.
* Replace the control solenoid valve assembly. Refer to Control Module References (See: Testing and Inspection/Programming and
Relearning) for replacement, setup, and programming.

DTC Descriptor
DTC P0965
- Pressure Control (PC) Solenoid 2 System Performance
DTC P0966
- Pressure Control (PC) Solenoid 2 Control Circuit Low Voltage
DTC P0967
- Pressure Control (PC) Solenoid 2 Control Circuit High Voltage
Diagnostic Fault Information
Typical Scan Tool Data
Circuit/System Description
The clutch pressure control solenoid 2 is part of the control solenoid valve assembly and is not serviced separately. The transmission control
module supplies 12 volts to the clutch pressure control solenoid 2 on the high side driver 2 circuit. The transmission control module controls the
pressure control solenoid 2 through the clutch pressure control solenoid 2 control circuit. The normally high clutch pressure control solenoid 2
flows fluid to the hybrid direct, 2-3-4 clutch and drive motor 2 when commanded ON.
