Solution K86412082 Tuesday, March 6, 2018 7:32:49 PM CET Solution Title (customer effect) Engine Diagnostic Trouble Codes ( DTC's ) P24A0 And P249F Lighting The Malfunction Indicator Lamp ( MIL ) - 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: For OBD15 And US14+OBD16 (Commonly Year Models 2016 and 2017, NonCommon Rail) Chassis: - Software improvements have been released to address these codes. If one or both codes are present and there are no other symptoms to indicate a physical issue, software should be checked and updated as necessary. - One or two modules can be affected by this update. Ensure the proper instructions are followed: - If the chassis has had containment software loaded previously: • Reprogram the Engine Control Module ( EMS ) ONLY - If the chassis has not had software containment • Reprogram the following modules in the order listed. 1. Engine Control Module ( EMS ) 2. Aftertreatment Control Module ( ACM ) - If the chassis returns for frequent recurrence of the code following the software update, normal Guided Diagnostic procedures will need to be followed. 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. Internal comments (BO) For US17+OBD2016 emission level vehicles, the next software release ( most likely in September 2017 ) will be an improvement to this diagnostic. Note: After the final corrective action is released for QJ 1-6720277401 rclo P249F, P24A0, EACH vehicle that has received the Containment Action 4 MUST be returned to a Dealership to load the final Software and Data Sets.
