P0563

DTC P0563 SYSTEM VOLTAGE HIGH




COMPONENT LOCATION

GENERAL DESCRIPTION
When the TP sensor's signal indicates closed throttle position and the engine is idling, the PCM adjusts the idle speed control actuator so that the engine runs at the correct idling speed, regardless of coolant temperature, load and etc. when the additional load applied in the engine, the air flow through the idle speed control actuator is increased momentarily to raise the idling speed.

DTC DESCRIPTION
PCM sets DTC P0563. if the PCM detects system voltage higher than the possible range of battery voltage.

DTC Detecting Condition:

MONITOR DTC STATUS

NOTE: If any codes relating to system voltage(P0560) is stored, do ALL REPAIRS associated with those codes before proceeding with troubleshooting

1. Connect scan tool and select "Diagnostic Trouble Codes(DTCs)" mode.
2. Press F4(DTAL) to select DTC information from the DTCs menu.
3. Confirm that "DTC Readiness Flag" indicates "Complete". If not, drive the vehicle within conditions noted in the freeze frame data or enable conditions.




4. Read "DTC Status" parameter.
5. Is parameter displayed "History(Not Present) fault"?

NOTE:
1. History (Not Present) fault: DTC occurred but has been cleared.
2. Present fault: DTC is occurring at present time.

YES: Fault is intermittent caused by poor contact in the sensor's and/or the PCM's connector, which was repaired but PCM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure

NO: Go to next step as below.

TERMINAL AND CONNECTOR INSPECTION
1. Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical Systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage
3. Has a problem been found?

YES: Repair as necessary and go to "Verification of Vehicle Repair" procedure

NO: Go to next step as below.

CHARGING SYSTEM INSPECTION
1. Check battery condition and Generator output.
2. Are battery conditions and Generator output both okay?

YES: Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "Verification of Vehicle Repair" procedure.

NO: Repair as necessary and go to "Verification of Vehicle Repair" procedure.

VERIFICATION OF VEHICLE REPAIR
After a repair, it is essential to verify that the fault has been corrected.
1. Connect scan tool and select "Diagnostic Trouble Codes(DTCs)" mode.
2. Press F4(DTAL) and confirm that "DTC Readiness Flag" indicates "Complete". If not, drive the vehicle within conditions noted in the freeze frame data or enable conditions.
3. Read "DTC Status" parameter.
4. Is parameter displayed "History(Not Present) fault"?

YES: System performing to specification at this time. Clear the DTC

NO: Go to the applicable troubleshooting procedure.
