DTC P069E (LUJ)
Diagnostic Instructions
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.
