DTC P0563 V6

DTC Description

This diagnostic procedure supports DTC P0563 System Voltage High.

Circuit Description

The transmission control module (TCM) continuously monitors the system voltage on the battery (circuit 740) and ignition (circuit 339) circuits. Higher then normal voltage may cause the solenoids inside the transmission to operate improperly or damage solid-state components inside the TCM.

When the TCM detects high voltage, DTC P0563 is a type C DTC.

Refer to Automatic Transmission Controls Schematics , LINK 73943, Automatic Transmission Internal Connector End Views , Automatic Transmission Control Module Connector End Views , and Automatic Transmission Related Connector End Views to aid the diagnosis.

Conditions for Running the DTC

The ignition is on.

Conditions for Setting the DTC

The TCM detects system voltage greater the 18 V for 10 seconds.

Action Taken When the DTC Sets
    • The TCM does not request the engine control module (ECM) to illuminate the check powertrain icon.
    •  The TCM records the operating conditions when the conditions for setting the DTC are met. The TCM records this information as a Failure Record.
    • The TCM stores DTC P0563 in TCM history.

Conditions for Cleaning the DTC
    • The TCM clears the DTC from the TCM history if the vehicle completes 40 warm-up cycles without a non-emission related diagnostic fault occurring.
    • Tech 2 can clear the DTC.

Diagnostic Aids
    • Observe the instrument cluster's multi-function display for messaging that would indicate the electrical system requires service.
    • Using Tech 2 in order to inspect all other modules for voltage related DTCs.
    • Running the engine with a battery Charger attached may cause DTC P0563 to set.
       - Inspect the charging circuit for high resistance.
       - Inspect the vehicle battery for open or sulphated cells.

Test Description

The following numbers refer to the step numbers in the diagnostic table :

3 The alternator warning indictor will illuminate if there is a problem with the charging system of the vehicle.

4 Checks the charging system voltage with a minimal load.

5 Checks if there is a difference between the Tech 2 reading and the voltage measure in an earlier step.

Has the Diagnostic System Check been preformed?

Go to Step 2

Refer to Diagnostic System Check - Automatic Transmission

2
  1. Connect Tech 2 to the DLC.
  2. Turn on the ignition, the engine off.

    3. Important:  Before Clearing the DTC, use the Tech 2 Freeze Frame/Failure Record in order to record the transmission parameters at the time DTC sets. Using Tech 2 to clear the DTC(s) erases the Freeze Frame/Failure Record records from the TCM.

  3. On Tech 2 selects:

    4. Transmission/Auto Transmission/Diagnostic Trouble Codes/Freeze Frame.

  4. Select the relevant DTC and not the parameters at the time of the DTC setting.
  5. On Tech 2 select:

    6. Diagnostic Trouble Codes/ Clear Engine & Transmission DTCs.

  6. Follow the instruction on Tech 2 and clear DTCs.
  7. On Tech 2 select:

    8. Diagnostic Trouble Codes/Read DTC Information.

Has DTC P0562 set?

Refer to DTC P0562

Go to Step 3

3
  1. Start the engine.
  2. Allow the engine to warm up to normal operating temperature.

    3. Is the alternator fail warning indicator illuminated?

Refer to Battery Charging

Go to Step 4

4
  1. Turn off all electrical accessories.
  2. Increase the engine speed to 2,000 RPM.
  3. Using the multimeter set to measure voltage, probe across the battery terminals. Record the measurement for reference.

    4. Does the mulitmeter display 12.5-14.5 V?

Go to Step 5

Refer to Battery Inspection/Test

5

Leave the engine running.

Go to Step 7

Go to Step 6

6

Did DTC P0563 reset?

Go to Step 7

Check for an intermittent fault in the circuit, refer to Testing for Intermittent Conditions and Poor Connections

7

Replace the TCM, refer to Transmission Control Module Replacement.

Is the action complete?

Go to Step 8

Perform the following procedure in order to verify the repair

  1. On Tech 2 select:

    2. Diagnostic Trouble Codes/Clear Engine & Transmission DTCs

  2. Following the instructions on Tech 2 and clear any DTCs.
  3. On Tech 2 select:

    4. Data Display/Transmission Data

  4. Operate the vehicle under the following conditions:
    5. • Start engine.
    • Allow the engine to warm up to normal operating temperature.
    • Observe the Ignition Voltage on Tech 2.
    • Ignition Voltage must remain below 18 V For 12 seconds.
  5. On Tech 2 select:

    6. Diagnostic Trouble Codes/ Read DTC Information.

Has DTC P0563 set?

Go to Step 2

Go to Step 9

On Tech 2 select:

Diagnostic Trouble Codes/Read DTC Information.

Does Tech 2 display any DTCs you have not diagnosed?

Refer to Diagnostic Trouble Code (DTC) List/Type

System OK

When all diagnosis and repairs are completed, Check the system for correct operation.
