Engine Electrical (FPCM)
DTC P0562 (FPCM)
Diagnostic Instructions
* Perform the Diagnostic System Check - Vehicle (Initial Inspection and Diagnostic Overview) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Initial Inspection and Diagnostic Overview) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Initial Inspection and Diagnostic Overview) provides an overview of each diagnostic category.
DTC Descriptor
DTC P0562
- System Voltage Low - FPCM
Diagnostic Fault Information
Circuit/System Description
The fuel pump control module (FPCM) monitors the system voltage to ensure that the voltage stays within the proper range. Damage to components, and incorrect data may occur when the voltage is out of range.
Conditions for Running the DTC
* The engine is running.
* The system voltage is between 9.5-18 V.
Conditions for Setting the DTC
The FPCM detects that the system voltage is less than 10 V.
Action Taken When the DTC Sets
DTC P0562 is a type C DTC.
Conditions for Clearing the DTC
DTC P0562 is a type C DTC.

Circuit/System Verification
1. Engine running, accessories OFF, measure and record the battery voltage at the battery terminals. The voltage should be between 12.6 and 15.0 V.
• If not within the specified range, refer to Charging System Test (Charging System Test).
2. Observe the scan tool FPCM Ignition 1 Signal parameter. The reading should be between 12.6 and 15.0 V.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connectors at the FPCM.
2. Ignition OFF and scan tool disconnected, open and close the driver door, and wait 30 seconds. Test for less than 5 Ohms between the ground circuit terminal 1 and ground.
• If greater than the specified range, test the ground circuit for an open/high resistance.
3. Verify that a test lamp illuminates between the B+ circuit terminal 32 and ground.
• If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
4. If all circuits test normal, replace the FPCM.
Repair Instructions
Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
