Circuit/System Verification
1. Ignition ON, verify with a scan tool the High Side Driver 1 parameter displays Enabled.
2. Engine Running, gear selector lever in Park position. Verify with a scan tool the following test status parameters displays OK:
* High Side Driver. 1 Ckt. Low Voltage Test Status
* High Side Driver. 1 Ckt. Open Test Status
* High Side Driver. 1 Ckt. High Voltage Test Status
3. Operate the vehicle within the Conditions for Running and Setting the DTC. The DTCs should not set. You may also operate the vehicle
within the conditions that you observed from the Freeze Frame/Failure Records data.
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 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:
* High Side Driver. 1 Ckt. Low Voltage Test Status
* High Side Driver. 1 Ckt. Open Test Status
* High Side Driver. 1 Ckt. High 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.
