* PC Sol. 5 Ckt. Low Voltage Test Status



瀚慖f any test status parameter displays Fault or Malfunction, replace the control solenoid valve assembly.



Repair Instructions



Important:



* 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.
