Title (customer effect)
Volvo Chassis - Diagnostic Trouble Codes ( DTC's ) P24A0 And P249F Lighting The
Malfunction Indicator Lamp ( MIL ) - US14+OBD15 (Commonly Model Year 2016)
And Newer (Includes Common Rail Fuel System)
Cause
Diagnostic Trouble Codes ( DTC ) P24A0 and P249F Lighting The Malfunction
Indicator Lamp ( MIL ). Troubleshooting steps leading to No Fault Found. The
following emissions levels are affected:
• OBD15 - Model Year 2016
• US14+OBD16 - Model Year 2017 (Non-Common Rail Fuel System)
• US17+OBD16 - Model Year 2018 (Common Rail Fuel System)
Solution
Overview
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.
Repair Information
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
- Software improvements have been released to address this code. Refer to the table
below:
For US14+OBD16
- Refer to FSB 284-065 Engine Control Module (ECM) and Aftertreatment Control
Module (ACM), Reprogramming.
• This bulletin is current as of 17 April 2018.
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 P249C 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 P249C.
