DTC Descriptor
DTC P069E: Fuel Pump Flow Control Module (FPCM) Requested MIL IlluminationCircuit/System Description
The fuel pump flow control module (FPCM) controls and monitors the operation of the fuel system. When the FPCM detects a fault and sets a DTC, the FPCM sends a serial data message to the engine control module (ECM) requesting the illumination of the malfunction indicator lamp (MIL). This DTC sets in the ECM when it receives a MIL request message from the FPCM.
Conditions for Running the DTC
The ignition is in crank, or the engine is running.
Conditions for Setting the DTC
The FPCM requests the ECM to illuminate the MIL.
Action Taken When the DTC Sets
DTC P069E is a Type A DTC.
Conditions for Clearing the DTC
DTC P069E is a Type A DTC.
Diagnostic Aids
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.
