Circuit/System Verification

1. Engine running, accessories OFF, measure and record the battery voltage at the battery terminals. The voltage should be between 12.6-15.0

volts.

瀚慖f the voltage is not within the specified range, or the charge indicator light is ON, refer to Charging System Test (See: Starting and

Charging/Testing and Inspection/Component Tests and General Diagnostics/Charging System Test).

2. Observe the scan tool TCM Ignition Voltage parameter. The reading should be between 12.6-15.0 volts.

3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

1. Ignition OFF, disconnect the 20-way harness connector at the transmission.

2. Connect the DT-47825-20 to the 20-way transmission harness connector.

3. Test for less than 10 ohms between the ground circuit terminals listed below and ground.

* Terminal 1

* Terminal 18

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

4. Ignition ON, verify that a test lamp illuminates between the ignition and B+ circuit terminals listed below and ground.

* Terminal 10

* Terminal 13

* Terminal 15

瀚慖f the test lamp does not illuminate, test the affected ignition or B+ circuit for a short to ground or an open/high resistance.

5. If all circuits test normal, 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.
