DTC Descriptor

DTC P069E

Fuel Pump Control Module Requested MIL Illumination

Circuit/System Description

The fuel pump control module constantly monitors the fuel pump control system for any condition which may adversely affect vehicle emissions. If a condition is detected, the fuel pump control module sets a DTC and sends a serial data message to the engine control module (ECM). The ECM sets DTC P069E to inform the technician that the fuel pump control module has set the emission related DTC. The serial data message sent by the fuel pump control module also contains a request for the ECM to illuminate the malfunction indicator lamp (MIL).

The technician can observe the DTC that was set by the fuel pump control module by reviewing the ECM Freeze Frame records on the scan tool. The ECM Freeze Frame records also contain the engine operating conditions present when the fuel pump control module DTC set.

Conditions for Running the DTC

The ignition is ON, or the engine is running for greater than 3 s.

Conditions for Setting the DTC

The ECM receives a serial data message from the fuel pump control module indicating that an emission related DTC has set in the fuel pump control module.

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:

• Do not replace the engine control module for this DTC. DTC P069E is an informational DTC.
• Correct any engine control and communication DTCs before diagnosing fuel pump control module DTCs.

1. Verify there are no engine control or communication DTCs set.

• If a DTC is set

Refer to Diagnostic Trouble Code (DTC) List - Vehicle .

• If a DTC is not set

4. Verify there are no fuel pump control module DTCs set.

• If a DTC is set

Refer to Diagnostic Trouble Code (DTC) List - Vehicle .

• If a DTC is not set

3. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
4. Verify the DTC does not set.

• If the DTC sets

Refer to Diagnostic Trouble Code (DTC) List - Vehicle .

If the DTC does not set

5. All OK.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the repair.

DTC P0700 OR P1700

Diagnostic Instructions

• Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
• Review Strategy Based Diagnosis for an overview of the diagnostic approach.
• Diagnostic Procedure Instructions provides an overview of each of the diagnostic category.

DTC Descriptor

DTC P0700

Transmission Control Module Requested MIL Illumination

DTC P1700

Transmission Control Module (TCM) Requested SVS Illumination

Circuit/System Description

The transmission control module (TCM) constantly monitors the transmission system for any condition which may adversely affect vehicle emissions. If a condition is detected, the TCM sets a DTC and sends a serial data message to the engine control module (ECM). The ECM sets DTC P0700 or DTC P1700 to inform the technician that the TCM has set the emission related DTC. The serial data message sent by the TCM also contains a request for the ECM to illuminate the malfunction indicator lamp (MIL) The technician can observe the DTC that was set by the TCM by reviewing the ECM Freeze Frame records on the scan tool. The ECM Freeze Frame records also contain the engine operating conditions present when the transmission DTC set.

Conditions for Running the DTC

• The ignition is ON or the engine is operating.
• The DTC runs continuously.

Conditions for Setting the DTC

The ECM receives a serial data message from the TCM indicating that an emission related DTC has set in the TCM.

Action Taken When the DTC Sets

DTC P0700 and DTC P1700 are Type A DTCs.

Conditions for Clearing the MIL/DTC

DTC P0700 and DTC P1700 are Type A DTCs.

Diagnostic Aids

Communication codes, U-codes, as well as powertrain codes, P-codes, set in the TCM can cause the ECM to set DTC P0700 or DTC P1700.

Circuit/System Verification

NOTE:

• Do not replace the engine control module for these DTCs. DTC P0700 or DTC P1700 are informational DTCs.
• Correct any engine controls and communication DTCs before diagnosing transmission control module DTCs.

1. Verify that there are no engine controls or communication DTCs set.

• If a DTC is set

Refer to Diagnostic Trouble Code (DTC) List - Vehicle for diagnosis of engine control or communications DTCs.

• If a DTC is not set

2. Verify that there are no transmission control module DTCs set.

• If a DTC is set

Refer to Diagnostic Trouble Code (DTC) List - Vehicle for diagnosis of transmission control module DTCs.

• If a DTC is not set

3. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
4. Verify the DTC does not set.

• If the DTC sets

Refer to Diagnostic Trouble Code (DTC) List - Vehicle .

• If the DTC does not set

5. All OK.
