Title
Volvo Chassis - Diagnostic Trouble Codes ( DTC's ) P24A0 And P249F Lighting The
Malfunction Indicator Lamp ( MIL ) - US14+OBD15, US14+OBD16 (Common Model
Years 2016 And 2017), US17+OBD16 And Newer ( Common Rail Fuel System, Model
Year 2018)
Cause
Vehicles may display the MIL and one or both of the following DTCs:
P24A0 - Closed Loop DPF Regeneration Control At Limit - Temperature Too
Low
P249F - Excessive Time To Enter Closed Loop DPF Regeneration Control
These DTCs set from monitors on operations requiring Aftertreatment Hydrocarbon
Injector ( AHI, 7th Injector) input, including:
Moving Crystal Sublimations ( OBD15 and OBD16 emissions levels )
Moving Sulfur Regenerations ( US17 / OBD2016 emission level only )
These operations run in the background and are transparent to the driver. The fault codes
do not inhibit regeneration or cause any operational problem with the vehicle except
for the MIL illuminating. The regen will continue normally even with the fault codes
present. The faults may set over a several day period due to the amount of time it takes
to complete some moving regenerations.
Solution
Verify the chassis emissions level
- Details can be found in the Product Details box on the Product tab in PTT as seen below:
Review the Detailed Status Information for the relevant code on the DTC Readout.
For US14+OBD15 And US14+OBD16
Software improvements have been released for both emissions levels to address this DTC. Field
Service Bulletins with information and instructions have been published for each emissions
level. Both FSBs can be found under the Service tab in Impact, Function Group 284. The
articles can also be searched for by Title. Refer to the chart below for the correct bulletin
information:
Emissions Level
Field Service Bulletin
(Model Year)
US14+OBD15
FSB 284-064 Engine Control Module (ECM) and
(2016)
Aftertreatment Control Module (ACM), Reprogramming
US14+OBD16
FSB 284-065 Engine Control Module (ECM) and
(2017)
Aftertreatment Control Module (ACM), Reprogramming
If the Bulletin does not appear when searched with either VIN or Chassis information entered,
search by model:
1. Clear any chassis information from the Search box.
2. Select or enter the applicable model.
3. Make sure Title is selected in the Search By field. Enter the correct Bulletin title in the
text entry field.
4. Press the Search button. The operation will appear in the results window.
5. Select the correct vehicle configuration from the list that appears as shown below:
For US17+OBD16 (Common Rail Fuel System) chassis:
Verify that EMS and ACM software do not have any updates available
Perform a sulfur regen using Premium Tech Tool ( PTT ) and clear DTCs.
This will temporarily resolve the fault codes. Do Not change any components on
subject vehicles with these fault codes.
If software is found to be current, diagnosis should only proceed if the Confirmed DTC
status for P249F/P24A0 is True as shown above. If the status is False, other symptoms or fault
codes should be diagnosed and the codes cleared when complete.
If any other symptoms or related codes are present, they should be diagnosed prior to
beginning steps for P249F/P24A0.
