Conditions for Setting the DTC
The TCM detects system voltage greater than 18 V for 10 seconds.
Action Taken When the DTC Sets
•
The TCM does not request the engine control module (ECM) to illuminate the MIL.
• 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 Clearing the DTC
•
The TCM clears the DTC from 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.
• Use Tech 2 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 indicator 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.
