| DTC Descriptor |
DTC P069E
Fuel Pump Control Module Requested MIL Illumination
| Circuit/System Description |
The fuel pump control module uses the serial data network to signal the engine control module (ECM) that the fuel pump control module is requesting malfunction indicator lamp (MIL) illumination. A DTC is set in the fuel pump control module, and the request for MIL illumination is sent when the fuel pump control module determines that a failure that affects emissions has occurred in the fuel pump control system. When the ECM receives the message from the fuel pump control module, DTC P069E will set in the ECM.
| Conditions for Running the DTC |
The ignition is ON or the engine is running.
| Conditions for Setting the DTC |
The fuel pump control module requests the ECM to illuminate the MIL.
| Action Taken When the DTC Sets |
| • |
DTC P069E is a Type A DTC.
|
|
| • |
DTC P069E will continue to be current or active as long as the fuel pump control module is requesting MIL illumination.
|
|
| Conditions for Clearing the DTC |
DTC P069E is a Type A DTC.
| Diagnostic Aids |
Communication codes, U-codes, as well as powertrain codes, P-codes, set in the fuel pump control module will cause the fuel pump control module to request DTC P069E to be set in the ECM.
