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 for greater than 3 s.
- The DTC 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.

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.

Circuit/System Verification

Note: Correct any engine controls and communication DTCs before diagnosing fuel pump control module DTCs.

1. DTC P069E is an informational DTC. If there are no engine controls or communication DTCs, refer to Diagnostic Trouble Code (DTC) List - Vehicle for diagnosis of fuel pump control module DTCs. Do not replace the ECM for this DTC.
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.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the repair.
