DTC Descriptor
DTC P069E 00
- Fuel Pump Control Module (FPCM) Requested MIL Illumination




Circuit/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.
