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:
* 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
锟斤拷If any test status parameter displays Fault or Malfunction, replace the Q8 control solenoid valve assembly.
