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 5 Performance Test Status
* Pressure Control Solenoid Valve 5 Control Circuit High Voltage Test Status
* Pressure Control Solenoid Valve 5 Control Circuit Low Voltage Test Status
瀚慖f any test status parameter displays Fault or Malfunction, replace the Q8 control solenoid valve assembly.

Diagnostic Fault Information
Typical Scan Tool Data
Circuit/System Description
The torque converter clutch (TCC) pressure control solenoid is part of the control solenoid valve assembly which has no serviceable parts. The
normally low TCC PC solenoid regulates oil pressure to the TCC regulator valve and TCC control valve. Increasing TCC PC solenoid oil pressure
increases oil pressure to the torque converter to apply the clutch. The TCM varies the current to the TCC PC solenoid through a low side driver.
