This instruction show you guide on how to diagnose rough running or stalling for Detroit Diesel Gen5 DD platform engine.<\/p>\n

Preparations:<\/strong><\/p>\n

2022 Detroit Diesel Diagnostic Link DDDL 8.15 8.09 Free Download<\/a><\/p>\n

Procedures:<\/strong><\/p>\n

1.Connect DiagnosticLink .<\/p>\n

2.Turn ignition ON (key ON, engine OFF).<\/p>\n

3.Are any of the following fault codes present?<\/p>\n

SPN 1077\/FMI 7 Rail Pressure Deviation<\/p>\n

SPN 157\/FMI 16 Rail Pressure Deviation<\/p>\n

SPN 3250\/FMI 0 DOC Outlet Temperature Very High<\/p>\n

SPN 3246\/FMI 0 DFP Outlet Temperature Very High<\/p>\n

3a Yes; perform the troubleshooting for the fault code.<\/p>\n

3b No; Go to step 4.<\/p>\n

4.Using DiagnosticLink, Key ON, Engine OFF (KOEO), monitor the EGR delta P voltage with the coolant temperature above 65\u00b0C (150\u00b0F). Is the EGR Delta P voltage between 0.55 to 0.82 volts?<\/p>\n

4a Yes; Go to step 5.<\/p>\n

4b No; perform the troubleshooting for SPN411\/FMI 13.<\/p>\n

 <\/p>\n

WARNING<\/p>\n

PERSONAL INJURY<\/p>\n

Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.<\/p>\n

Always start and operate an engine in a well ventilated area.<\/p>\n

If operating an engine in an enclosed area, vent the exhaust to the outside.<\/p>\n

Do not modify or tamper with the exhaust system or emission control system.<\/p>\n

WARNING<\/strong><\/p>\n

ENGINE EXHAUST<\/p>\n

To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is toxic.<\/p>\n

WARNING<\/strong><\/p>\n

PERSONAL INJURY<\/p>\n

To avoid injury before starting and running the engine, ensure the vehicle is parked on a level surface, parking brake is set, and the wheels are blocked.<\/p>\n

5.Disconnect the delta P electrical sensor. Key ON Engine Running, idle the engine for 30 seconds, then using the accelerator pedal, increase the engine to 1000 rpm. Did the engine stop surging?<\/p>\n

5a Yes; clean the Exhaust Gas Recirculation Venturi ports and verify repairs.<\/p>\n

5b No; Go to step 6.<\/p>\n

Note : If the fuel mass is over 50 mg\/st at 600 rpm (engine at operating temperature), abort the FSIC routine and Go to step 7.<\/p>\n

Note:See examples of erratic pressure showing (1) ASL001 Rail pressure and (2) AS098 Desired rail pressure.<\/p>\n

6.Run an automatic Fuel System Integrity Check (FSIC) test. Review the automatic FSIC log file. Does ASL001 Rail Pressure have a saw tooth pattern or does the desired rail pressure and rail pressure deviate by more than 50 bar (725 psi)?<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

6a Yes; replace the Quantity Control Valve (QCV).<\/p>\n

6b No; Go to step 7.<\/p>\n

 <\/p>\n

7.Review the automatic FSIC log file. At 600 rpm, is fuel mass over 50 mg\/st?<\/p>\n

7a Yes; replace both engine brake solenoids.<\/p>\n

7b No; Go to step 8.<\/p>\n

 <\/p>\n

8.Check for aerated fuel. Refer to section \u201cAerated Fuel Test \u201d . Is fuel aerated?<\/p>\n

8a Yes; if fuel is aerated, repair or replace as necessary.<\/p>\n

8b No; if fuel is not aerated, Go to step 9.<\/p>\n

 <\/p>\n

9.Check for loose connections, kinked fuel lines or issues related to the fuel system. Were any issues found with the fuel system?<\/p>\n

9a Yes; repair or replace as necessary.<\/p>\n

9b No; Go to step 10.<\/p>\n

Note : If rust is found in the filters, Refer to section \u201cDiesel Exhaust Fluid in Fuel\u201d .<\/p>\n

 <\/p>\n

10.Remove the Fuel Prefilter and Fuel Coalescer\/Final Filter. Check for damaged or missing seals at the bottom of filters. Are damaged or missing seals at the bottom of the filters?<\/p>\n

For Gen 5 DD13 and DD15 engines: Refer to section \u201cRemoval of the Fuel Prefilter\u201d and Refer to section \u201cRemoval of the Coalescer\/Final Filter\u201d .<\/p>\n

10a Yes; replace fuel filters as necessary.<\/p>\n

10b No; Go to step 11.<\/p>\n

11.Check air vents at the top of the Fuel Coalescer\/Final filter for blockage. Is any blockage found?<\/p>\n

\"\"<\/a><\/p>\n

11a Yes; replace the fuel filter as needed.<\/p>\n

For Gen 5 DD13 engines: Refer to section \u201cInstallation of the Coalescer\/Final Filter\u201d .<\/p>\n

For Gen 5 DD15 engines: Refer to section \u201cInstallation of the Coalescer\/Final Filter\u201d .<\/p>\n

 <\/p>\n

11b No; Go to step 12.<\/p>\n

Note : Use the appropriate parts catalog to verify injector part numbers.<\/p>\n

12.Verify the fuel injector(s) part number is correct for engine application. Is the fuel injector(s) part number correct?<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

12a Yes; Go to step 13.<\/p>\n

12b No; install correct fuel injector(s).<\/p>\n

 <\/p>\n

13.Compare calibration code(s) using the DiagnosticLink panel \u201cInjector Codes\u201d with six-digit calibration code(s) on the fuel injector(s). Do the calibration codes match the appropriate cylinder?<\/p>\n

\"\"<\/a><\/p>\n

13a Yes; Go to step 14.<\/p>\n

13b No; correct the calibration codes using DiagnosticLink.<\/p>\n

 <\/p>\n

14.Check valve lash and engine brake rocker lash. Is valve lash within specification?<\/p>\n

14a Yes; Go to step 15.<\/p>\n

14b No; readjust lash and retest.<\/p>\n

15.Using DiagnosticLink\u00ae, perform a relative compression test; Refer to section \u201cRelative Cylinder Compression Test\u201d . Are the results in range?<\/p>\n

15a Yes;replace all six fuel injectors.<\/p>\n

For Gen 5 DD13 engines: Refer to section \u201cRemoval of the Fuel Injector\u201d .<\/p>\n

For Gen 5 DD15 engines: Refer to section \u201cRemoval of the Fuel Injector\u201d .<\/p>\n

15b No; perform a Mechanical Cylinder Compression Test. Refer to section \u201cMechanical Cylinder Compression Test\u201d .<\/p>\n
