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.

DTC Descriptor

DTC P0563

- System Voltage High

Diagnostic Fault Information

Circuit/System Description

The following control modules monitor the system voltage to ensure that the voltage stays within the proper range:

* Engine control module

* Fuel pump control module

* Transmission control module

Damage to components, and incorrect data may occur when the voltage is out of range.
