NOTE: For 2011 models this code sets when SPN 5246/FMI 16 is present and the fuel was refilled more than 15 percent or SPN 5246/FMI 16 is present, 30 gallons of fuel has been used and the vehicle has been restarted. NOTE: For 2010 models this code sets when SPN 5246/FMI 16 is present and the fuel was refilled more than 30 percent or SPN 5246/FMI 16 is present, 350 gallons of fuel has been used and the vehicle has been restarted. DESCRIPTION:Regulatory fault ignored – final action speed limiting. MONITORED PARAMETER:SCR and DPF sensors. TYPICAL ENABLING CONDITIONS:Always Enabled MONITOR...

NOTE: For 2011 models, this code sets when the vehicle has been driven for 30 miles while a code is present for the DEF tank level, DEF metering valve, DEF pump, NOx sensors, Blocked DEF line, DEF quality, NOx efficiency, SCR harness and/or SCR sensor. NOTE: For 2010 models, this code sets when the vehicle has been driven for 10 hours or 500 miles while a code is present for the DEF tank level, DEF metering valve, DEF pump, NOx sensors, Blocked DEF line, DEF quality, NOx efficiency, SCR harness and/or SCR sensor. DESCRIPTION:Regulatory fault ignored – derate on. MONITORED...

NOTE: For 2011 this code sets after SPN 5246/FMI 15 is present and the vehicle has been driven for 220 miles. NOTE: For 2010 this code sets after SPN 5246/FMI 15 is present and the vehicle has been driven for 30 hours or 1500 miles. DESCRIPTION:Regulatory fault ignored – final action pending. MONITORED PARAMETER:SCR and DPF sensors. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:Two seconds DASH LAMPS:CEL ENGINE REACTION:40% derate, Limited to 55 MPH. VERIFICATION:1. Parked SCR efficiency test for extended SCR faults.2. High idle regeneration for DPF and NOx faults. NOTE: For 2010 emission engines,...

DESCRIPTION:This fault code sets when the motor control module (MCM) detects that there is EGR pressure when the engine is not running. MONITORED PARAMETER:EGR delta pressure. TYPICAL ENABLING CONDITIONS:Coolant temperature greater than 80°C (176°F) and ignition is cycled off for 10 seconds. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:15 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:1. Run the engine until the coolant temperature is greater than 80°C (176°F).2. Turn the ignition off for 15 seconds.3. Turn the ignition on as a recheck for the fault code. PROBABLE CAUSES:1. EGR delta p sensor failure.2. EGR delta...

NOTE: This code sets after SPN 5246/FMI 15 is present and the speed limit has been reduced to 55 mph. DESCRIPTION:Regulatory fault ignored – final action pending. MONITORED PARAMETER:SCR and DPF sensors. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:Two seconds DASH LAMPS:CEL ENGINE REACTION:40% derate, limited to 55 mph. VERIFICATION:1. Parked SCR efficiency test for extended SCR faults.2. High idle regeneration for DPF and NOx faults. NOTE: If code 3364-xx present, fix that first. PROBABLE CAUSES:1. Check all DEF supply lines for damage or leaks.2. DEF tank is contaminated with gas, diesel, water, etc…3. SCR outlet...
