DTC Descriptor
DTC P069E 00: Fuel Pump Control Module (FPCM) Requested MIL IlluminationCircuit/System Description
The fuel pump 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 GMLAN 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 detects a fuel system related fault and sets a DTC.
Action Taken When the DTC Sets
DTC P069E is a C type DTC.
Conditions for Clearing the DTC
DTC P069E is a C type 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.

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 ON or the engine is operating. |
| • | DTC P069E runs continuously. |
Conditions for Setting the DTC
The ECM receives a serial data message from the FPCM, in order 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.

Circuit/System Verification
- DTC P069E is an informational DTC. If there are no Engine Controls DTCs, refer to Diagnostic Trouble Code (DTC) List - Vehicle for diagnosis of the FPCM.
- Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
