Trouble Code: P0562



System Voltage Low

Trouble Code: P0562



System Voltage Low

Possible Causes:

Inspect for the following conditions:



Loose or damaged terminals at the generator
 
Loose or worn generator drive belt
 
Inspect the connectors at the TCM, the transmission, and all other circuit connecting points for an intermittent condition. Refer to Testing for Intermittent Conditions and Poor Connections .
 
Inspect the circuit wiring for an intermittent condition. Refer to Testing for Electrical Intermittents .
 

Trouble Code: P0563



System Voltage High

Trouble Code: P0563



System Voltage High

Possible Causes:



Use the scan tool 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 sulfated cells.
 

 

Trouble Code: P0563



System Voltage High

Possible Causes:



A possible cause of this DTC could be overcharging with a battery charger or jump starting.
 
A high voltage value in multiple modules indicates a concern in the charging system.
 

Trouble Code: P0575



Cruise Control Switch Signal Circuit

Possible Causes:



This DTC may be stored as a history DTC without affecting the operation of the BCM. If stored only as a history DTC and not retrieved as a current DTC, do not replace the BCM.
 
If this DTC is retrieved as both a current and history DTC, replace the BCM.
 

Trouble Code: P0575



Cruise Control Switch Signal Circuit

Possible Causes:



This DTC may be stored as a history DTC without affecting the operation of the BCM. If stored only as a history DTC and not retrieved as a current DTC, do not replace the BCM or ECM.
 
If this DTC is retrieved as both a current and history DTC, replace the BCM.
 
Using the Failure Records data may help locate an intermittent condition. If you cannot duplicate the DTC, the information in the Failure Records can help determine how many miles since the DTC set. The Fail Counter and Pass Counter can help determine how many ignition cycles that the diagnostic test reported a pass and/or a fail.
 

Trouble Code: P0601



Control Module Read Only Memory (ROM)

Trouble Code: P0602



Control Module Not Programmed

Trouble Code: P0603



Control Module Long Term Memory Reset

Trouble Code: P0604



Control Module Random Access Memory (RAM)

Trouble Code: P0605



Control Module Programming Read Only Memory

Trouble Code: P0606



Control Module Internal Performance

Trouble Code: P0607



Control Module Performance

Trouble Code: P060E



Control Module Throttle Position (TP) System Performance

Trouble Code: P0615



Starter Relay Control Circuit

Possible Causes:



Ignition system DTCs set with the ignition switch in the START position if the CRNK relay or the starter is inoperative. When the ECM/PCM enables starter operation, the ECM/PCM also initiates the diagnostic test routines for DTCs P0335, P0340, and P0385. If a condition exists which prevents the engine from cranking, the ECM/PCM will not receive signal input from the CKP and CMP sensors, and the DTCs will set. Reviewing the Fail Records vehicle mileage since the diagnostic test last failed may assist in diagnosing the condition. The information may help determine how often the condition that set the DTC occurs.
 

Trouble Code: P0621



Generator L-Terminal Circuit

Trouble Code: P0622



Generator F-Terminal Circuit

Trouble Code: P0622



Generator F-Terminal Circuit

Possible Causes:



On vehicles equipped with a sense circuit connected to the voltage regulator. This circuit must have voltage for the charging system to operate properly. This circuit is used as a reference to control system voltage. All circuits must be tested at the generator before replacing any components. refer to system schematic to confirm if the vehicle being serviced uses the sense circuit as part of the charging system.
 

Trouble Code: P0641



5-Volt Reference 1 Circuit

Trouble Code: P0645



Air Conditioning (A/C) Clutch Relay Control Circuit.

Possible Causes:



Important: Be sure to verify that the ECM or PCM engine grounds are secure and clean. If DTC P0645 cannot be duplicated, reviewing the Failure Records vehicle millage since the diagnostic test last failed may help determine how often the condition that caused the DTC to set occurs. This may assist in diagnosing the condition. If the condition is not present, refer to Testing for Intermittent Conditions and Poor Connections .
 

Trouble Code: P0650
