Code and Description Conditions which Generate this Code System Response
1779-5 Fuel Rail #1 Pressure Valve Solenoid : Current Below Normal The ECM detects current flow through the circuit for the solenoid that is below the acceptable value. A snapshot is taken. The code is logged. The engine may shut down and/or the engine may not start due to low fuel pressure. This code is disabled while the engine is cranking. The ECM will continue to fire the solenoid. If the ECM detects acceptable current flow during five successive attempts to fire the solenoid, the active code is cleared.
1779-6 Fuel Rail #1 Pressure Valve Solenoid : Current Above Normal The ECM detects current flow through the circuit for the solenoid that is above the acceptable value.
1780-5 Fuel Rail #2 Pressure Valve Solenoid : Current Below Normal The ECM detects current flow through the circuit for the solenoid that is below the acceptable value. A snapshot is taken. The code is logged. The engine may shut down and/or the engine may not start due to low fuel pressure. This code is disabled while the engine is cranking. The ECM will continue to fire the solenoid. If the ECM detects acceptable current flow during five successive attempts to fire the solenoid, the active code is cleared.
1780-6 Fuel Rail #2 Pressure Valve Solenoid : Current Above Normal The ECM detects current flow through the circuit for the solenoid that is above the acceptable value. Note: The automatic cylinder cutout test is disabled while any of these codes are active.Automatic Configuration of the Solenoid DriversThe connectors for the solenoids are interchangeable. The ECM determines the connector that is connected to each solenoid during each engine start cycle. For this reason, you must determine the configuration of the wiring before you troubleshoot the system. This process is explained in the troubleshooting steps within this procedure.

Information for the high pressure fuel pump's electrical circuits
Test Step 1. INSPECT THE ELECTRICAL CONNECTORSNote: Carefully following this procedure is a good way to identify an intermittent problem.
Perform a visual inspection of the wiring between the high pressure fuel pump and the ECM. Look for the following problems:
Harness damage that is caused by chafing
Harness damage that is caused by excessive heat
Inspect the wiring and the connectors at the high pressure fuel pump:
Look for moisture on the wiring and on the connectors.
Pull on each wire. This test verifies that the wire is properly crimped to the terminal and that the terminal is properly inserted into the connector.
Inspect the P2 connector:
Look for moisture on the wiring and on the connector.
Pull on each wire. This verifies that the wire is properly crimped to the terminal and that the terminal is properly inserted into the connector. Expected Result:There is a problem with the wiring or with a connector.Results:
Yes - There is a problem with the wiring or with a connector.Repair: Clean the connectors, if necessary. Replace parts, if necessary. Verify that the problem is resolved.STOP
No - The wiring and the connectors are OK. Proceed to Test Step 2.Test Step 2. DETERMINE THE CONFIGURATION OF THE WIRINGNote: Proceed to the next test step when you have determined the configuration of the wiring.
Perform the following procedure if the diagnostic code is 1780-5 or 1780-6.
Disconnect the harness connector for solenoid 1.
Measure the resistance between terminal 1 and terminal P2-77. The configuration of the wiring is according to Table 2 if the resistance measurement indicates continuity. Continue with this procedure if the resistance measurement indicates an open circuit.
