Circuit/System Description
The fuel pump flow control module (FPCM) monitors the ignition voltage circuit in order to determine if the voltage is within the normal operating range.
Conditions for Running the DTC
The engine is running.
Conditions for Setting the DTC
The FPCM detects that the IGN voltage is less than 6.0 volts.
Action Taken When the DTC Sets

Circuit/System Testing
- Verify that DTC P0562 is not set.
- Ignition OFF, disconnect the harness connector of the K27 FPCM.
- Ignition ON, test for greater than 11 V between the IGN voltage circuit terminal 32 and ground.
- If all circuits test normal, replace the K27 FPCM.
| ⇒ | If DTC P0562 is set, refer to DTC P0562. |
| ⇒ | If less than the specified voltage, test the IGN voltage circuit for a short to ground or an open/high resistance. If the circuit test normal and the F67UA fuse is open, test the voltage circuit for a short to ground. If the circuit tests normal, test or replace the Run/Crank relay. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
