Circuit/System Testing
Note: You must perform the Circuit/System Verification first.
1. Ignition OFF, remove the 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/6T70/6T75 - Automatic Transmission/Control
Solenoid Valve and Transmission Control Module Assembly Inspection).
3. Place the control solenoid valve assembly on a clean work surface near the transmission assembly.
4. Connect the DT-47825-20 adapter harness between the vehicle wire harness electrical connector, and the control solenoid valve assembly
electrical connector.
5. Ignition ON, verify with a scan tool the following test status parameters display OK:
* TCC PC Sol. Perf. Test Status
* TCC PC Sol. Ctrl. Ckt. High Voltage Test Status
* TCC PC Sol. Ctrl. Ckt. Low Voltage Test Status
瀚慖f any test status parameter displays Fault or Malfunction, replace the control solenoid valve assembly.
Repair Instructions
Note:
* 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.
