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

* Vehicle ON for greater than 3 s.
* DTC P069E runs continuously when the above condition is met.

Conditions for Setting the DTC

The fuel pump control module requests the ECM to illuminate the MIL.
