Diagnostic Trouble Codes for Excessive Soot Load
J1939 Code Description Information that Relates to the Code
3719-16 Diesel Particulate Filter #1 Soot Load Percent : High - Moderate Severity (2) The estimated soot load is high. The ECM shuts down the engine when this code becomes active for the first time. The engine can be started and operated. Engine power is gradually derated as the soot load increases.
3719-0 Diesel Particulate Filter #1 Soot Load Percent : High - Most Severe (3) The estimated soot load is high. Engine operation is limited to 60 second intervals when the Cat® Electronic Technician (ET) is not communicating with the ECM.
3715-31 Diesel Particulate Filter Active Regeneration Inhibited Due to Permanent System Lockout The estimated soot load is high. The engine may not operate properly. Factory passwords are required in order to clear this code.
Follow the troubleshooting procedure in order to determine the root cause of the problem. Illustration 1 and Illustration 2 show an overview of the troubleshooting procedure. Follow the steps in order.
Illustration 1 g02751679
Illustration 2 g02751681Troubleshooting Procedure
Determine if DPF Differential Pressure Requires Replacement of DPF. Perform this Step only if you are troubleshooting a 3715-31 code. Otherwise, proceed to Step 2.Use the Caterpillar Electronic Technician (ET) to view the differential pressure across the DPF. If there are two filters, view the differential pressure across both of the filters. The differential pressure is indicated by the following parameters:
"Diesel Particulate Trap #1 Differential Pressure"
"Diesel Particulate Trap #2 Differential Pressure"You may need to create a group in order to view these parameters.Start the engine. Increase the engine speed to 1400 rpm. Monitor the differential pressure for 30 seconds. Stop the engine.Results:The differential pressure exceeds 15.0 kPa (2.1 psi).Repair:Replace with the appropriate DPF. Use factory passwords in order to clear the 3715-31 code. Return the vehicle to service.Results:The differential pressure is less than 15.0 kPa (2.1 psi).Repair:Do not replace the DPF. Use factory passwords in order to clear the 3715-31 code. Continue to Step 2.
Verify that ARD Disable Switch is not Disabling Regens If the vehicle is equipped with an ARD disable switch, verify that the switch is not disabling the Aftertreatment Regeneration Device (ARD). Refer to the vehicles service manual in order to determine the proper operation of the switch.Proceed to Step 3.
Check for Associated Diagnostic Trouble Codes Troubleshoot any diagnostic codes that relate to the following systems or conditions:
Low boost/ air system faults
ARD
Clean Gas Induction System (CGI)
Injector/ fuel system faultsTroubleshoot the systems in the order that is listed above if there are diagnostic codes for more than one of the systems.Proceed to Step 4

Typical ARD combustion head
(1) Electrical connector for the heated nozzle (ARD combustion head with a heated nozzle)
(2) Air line for the pressurized air (ARD combustion head that uses pressurized air for cleaning the nozzles)
Determine the Type of Cleaning System for the Nozzles Inside the ARD Combustion Head Determine the type of cleaning system for the nozzles inside the ARD combustion head.Results:The ARD purge air system is used to clean the nozzles.Repair:Contact your local Caterpillar Technical Communicator for information on updating the system.STOPResults:An electric heating element is used to clean the nozzles.Proceed to Step 5.
Perform the "Engine Air System Verification Test" Perform the "Engine Air System Verification Test". Refer to Troubleshooting, "Air System Verification Test" for information on the test, if necessary.Troubleshoot the test results if the test results are unacceptable. Then, proceed to "ARD Combustion Air –Test".Proceed to Step 6 if the results of the "Engine Air System Verification Test" are acceptable.
Inspect the DPF Perform this Test Step if all of the following conditions are true:
The ARD disable switch was not disabling the ARD.
The results of the "Engine Air System Verification Test" are acceptable.
Remove the inlet section from the DPF. Inspect the inside of the inlet section and the front face of the DPF. Look for oil and for excessive soot. The presence of a small amount of soot is a normal condition. Contact your local Technical Communicator for Caterpillar On-highway Truck Engines if you suspect that the amount of soot is excessive. Continue with this procedure after you have received guidance from the Technical Communicator.If oil is found, inspect the outlet of the turbocharger. Contact your local Technical Communicator for Caterpillar On-highway Truck Engines if oil is found. Continue with this procedure after you have received guidance from the Technical Communicator. Clean the oil from the inside of the inlet section of the DPF and the front face of the DPF. Assemble the DPF. Use Cat ET to disable the ARD. Set the value of the "Data Link ARD Disable Status" configuration parameter to "Disabled" in order to disable the ARD. Run the engine at 1400 rpm for 15 minutes. Then, proceed to the next test step.If no oil is found, leave the inlet section disconnected from the DPF. Use Cat ET to disable the ARD. Set the value of the "Data Link ARD Disable Status" configuration parameter to "Disabled" in order to disable the ARD.Perform a manual cylinder cutout test. Manually cut out each cylinder while the exhaust is monitored. Look for the smoke to disappear as each cylinder is cut out. Replace any injectors that cause the engine to smoke and run rough when the cylinder is not cut out. Clean the inside of the inlet section of the DPF and the front face of the DPF. Assemble the DPF. Run the engine at 1400 rpm for 15 minutes.Set the value of the "Data Link ARD Disable Status" configuration parameter to "Not Disabled" in order to enable the ARD. Proceed to Test Step 7.
Datalog a Stationary Regeneration Refer to Special Instruction, REHS3407, "Using the Caterpillar Electronic Technician (ET) Data Log" for information on using the data log.
Clear all active diagnostic and active event codes before starting the regeneration.
Configure the settings on the "General" tab according to the following information: Sample Rate - Enter a sample rate of 20 samples per minute.Duration - Enter a duration of 1 hour.
The data log must capture the following parameters. Create a group
