### DTC Descriptor

DTC P069E: Fuel Pump Flow Control Module (FPCM) Requested MIL Illumination

### Circuit/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

• | DTC U0109 is not set.

• | 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. The condition exists, then a 5 second delay for MIL ON.

### 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.

### Circuit/System Verification

1. 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.
2. 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.
