I have a Freightliner 122SD with a Detroit DD15 DDEC13. Vin#

OK. 247 below

116.1  SPN 247/FMI 14 - EPA07 - GHG14

SPN 247/FMI 14 (MCM Reported Ash Mileage is Lower than the CPC Stored Value)

Show/Hide Checkboxes

1. Connect DiagnosticLink® .
2. Turn the ignition ON (key ON, engine OFF).
3. Select DPF Ash Accumulator from the Actions Drop-down Menu.
4. Choose MCM Replacement Option, then select the Synchronize from the CPC radio button.
5. Verify that the MCM value has changed in the DPF Ash Accumulator window and that the 247/14 CPC fault is no longer active. MCM will change to a value that should be within 5% of the CPC displayed volume within 5-10 seconds of executing the routine. Clear all faults and release vehicle.

Regulatory Fault Ignored - Final Action (Speed Limit)Print

ECM: Detroit - DD15 GHG14 (2014-16)

Fault: SPN 5246 FMI 0 (ACM)

SPN: 5246

FMI: 0

NOTE: This code sets when SPN 5246/FMI 16 has been present for one hour of idle time, the vehicle has been restarted or six gallons of fuel has been used.

ENGINE REACTION:

1. Idle only, vehicle limited to 5 MPH.

2. Parked SCR efficiency test for extended SCR faults.

VERIFICATION:

High idle regeneration for DPF and NOx faults.

NOTE: For 2010 emission engines, if 5246-0, 5246-15, or 5246-16 are the only faults present, please troubleshoot code 3361-7 instead.

NOTE: This is a government mandated code which informs users that fault code has been active for longer then a government specified time interval.

3361 7 attached.

Show/Hide Checkboxes

ENGINE EXHAUST
To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is toxic.

PERSONAL INJURY
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.

HOT EXHAUST
During parked regeneration the exhaust gases will be extremely HOT and could cause a fire if directed at combustible materials. The vehicle must be parked outside.

NOTICE:

Running engine with DEF Dosing Unit disconnected will induce faults.

NOTICE:

Do not attempt to operate engine with the DEF lines disconnected. DEF pump runs and circulates DEF through the system at a limited rate (default) to aid in system cooling.

NOTE: NOx Inlet normal reading should be 0 to 50 ppm higher than the NOx Outlet reading.

1. Was another emission component-related fault code repaired prior to this step?
   1. Yes; perform a parked regeneration to verify repairs and clear fault codes.
   2. No; Go to step 2.
2. Use DEF test strip A0005850202 to check for diesel fuel or oil contamination of the DEF fluid; Refer to section "Checking Diesel Exhaust Fluid Quality" . Does the test strip or visual inspection indicate that the DEF is contaminated?
   1. Yes; for diesel fuel or oil contamination, refer to 13 TS-17 and refer to appropriate Original Equipment Manufacturer (OEM) literature for DEF tank cleaning/flushing procedures. Verify repair.
   2. No; Go to step 3.
3. Using a refractometer from the DEF Test Kit W060589001900, measure the DEF percentage. Is DEF percentage between 31 to 34%?
   1. Yes; Go to step 4.
   2. No; clean/flush the DEF tank, then Go to step 7. Refer to section "Flushing of the GHG14 Diesel Exhaust Fluid System" .
4. Turn ignition ON (key ON, engine OFF).
5. Visually check all DEF lines for physical damage (kinks, cracks, leaks and disconnects). Is any damage found?
   1. Yes; repair as necessary, Go to step 7.
   2. No;Go to step 6.
6. Unbolt DEF Dosing Unit from exhaust only. Do not disconnect DEF hoses or electrical connector. Refer to section "Removal of the GHG14 Dosing System Doser" .
7. Perform a DEF Quantity Test service routine and record the amount of DEF fluid level dispensed. Is the dispensed DEF fluid level between 108 to 132 mL (3.65 and 4.46 ounces)?
   1. Yes; reinstall DEF Dosing Unit. Go to step 8.
   2. No; replace DEF Dosing Unit. To verify repairs, Go to step 8.
8. Connect DiagnosticLink® . Monitor (chart) the following parameters.
   • ASL102 Engine Speed
   • AS018 Selective Catalyst Reduction (SCR) Inlet Temperature
   • AS019 SCR Outlet Temperature
   • AS035 SCR Inlet NOx sensor
   • AS036 SCR Outlet NOx sensor
   • AS101 NOx Conversion Efficiency
9. Start engine and perform a parked regeneration. Does the NOx conversion efficiency rise and stay above 85% (0.85) during the regeneration? Check after the regeneration to ensure SPN 3364/FMI 2 and all SPN 5246/FMI (any) faults go inactive. Refer to section "Performing a Parked Regeneration - EPA10/GHG14" .
   1. Yes; clear faults and release vehicle.
   2. No;Go to step 10.
10. Disconnect the DEF Dosing Unit electrical connector only. Leave Dosing Unit bolted to Aftertreatment and DEF hoses intact.
11. Inspect the harness connector for signs of damaged, bent, spread, corroded or unseated (pushed out) pins and signs of moisture in the connector or wire damage near the connector. Is damage or contamination found?
    1. Yes; repair as necessary. Perform a parked regeneration to verify repairs. Refer to section "Performing a Parked Regeneration Using DiagnosticLink®" .
    2. No;Go to step 12.
12. Start engine and perform a "Perform Performance Check - Low Temp ATD". After thirty minutes, are the NOx sensor values within 50 ppm of each other?
    1. Yes; Go to step 13.
    2. No; replace the Inlet NOx sensor. Perform a parked regeneration to verify repairs. Refer to section "Performing a Parked Regeneration Using DiagnosticLink®" .
13. Turn the ignition OFF.
14. Disconnect the Aftertreatment Control Module (ACM) 120-pin connector.
15. Inspect the ACM 120-pin connector and the 120-pin harness connector for signs of corrosion, spread, unseated (pushed out) or damaged pins, connector seal for damage (signs of water or oil intrusion) or signs of wire damage. Is damage or contamination found?
    1. Yes; repair as necessary. Perform a parked regeneration to verify repairs. Refer to section "Performing a Parked Regeneration Using DiagnosticLink®" .
    2. No;Go to step 16.
16. Install a test ACM. Perform a parked regeneration to verify repairs. Refer to section "Performing a Parked Regeneration Using DiagnosticLink®" .

Since you cannot build heat for a regen, I would check the 7 th injector and be sure there is no carbon wall in the down pipe preventing it from building heat.

What is the doser pressure to the injector?

Roy

So you have no doser pressure to the doser?

Roy

Do you have to the doser module?

Make sure your filters are good as well. Clogged fuel filters will cause low or no pressure to the doser.

Roy

Can you see the command on your scan tool?

OK, if you can see the command then replace the doser module.

Roy

You just said it was sending a command? Please explain.

Roy

OK, then you need to be sure there is no updated sftware available for this and also the ACM.

Did you get all the codes resolved?

Roy
