When the Aftertreatment Regeneration Device (ARD) requires troubleshooting, there will be multiple codes in order to assist the troubleshooting process. A "Soot Loading-High" code is not the cause of the fault. Troubleshoot one of the following associated codes in order to clear the fault that has caused the "Soot Loading-High" code:
3473-31 Aftertreatment #1 Failed to Ignite
3474-31 Aftertreatment #1 Loss of Combustion
3703-31 Particulate Trap Active Regeneration Inhibited Due to Inhibit Switch
3711-31 Particulate Trap Active Regeneration Inhibited Due to Low Exhaust Gas Temperature
3714-31 Particulate Trap Active Regeneration Inhibited Due to Temporary System Lockout
3750-31 DPF #1 Conditions Not Met for Active RegenerationTroubleshooting the associated codes may lead to a code that is the root cause of the fault.The following paragraph is an example of troubleshooting the engine system with "Associated Codes". After connecting the electronic service tool to an engine, the following codes are displayed:
A "Soot Loading - High" code (the high-level code)
An "Insufficient Temperature to Regenerate" code (the associated code)
A "Nozzle Not Responding" code (the code that is identified by the associated code as the cause of the fault)This example is the result of a fouled nozzle. The ARD was unable to increase the exhaust gas temperature enough to regenerate the Diesel Particulate Filter (DPF) because the fittings or the nozzle failed. The "Soot Loading-High" code was generated because the trap was unable to regenerate. The troubleshooting procedure that would be followed in this case would be the "Nozzle Not Responding" code, which will correct the other two codes.Engine operation must be kept to a minimum in order to minimize the amount of soot that is created. Follow the troubleshooting procedure in order to minimize the amount of engine operation.The Electronic Control Module (ECM) maintains an estimate of the soot load in the DPF. The estimate is based on the operating conditions of the engine. If the ECM estimates that the soot load is excessive, the ECM activates the applicable code.Note: After a regeneration and soot loading is reduced to 0%, the active soot loading code will not be logged or cleared for 5 minutes.
Table 1
Diagnostic Trouble Codes for Excessive Soot Load    
J1939 Code and Description    Information that Relates to the Code    
3719-16 High Diesel Particulate Filter #1 Soot Loading - Level 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 High Diesel Particulate Filter #1 Soot Loading - Level 3     The estimated soot load is very high. Engine operation is limited to 30 second intervals when the electronic service tool is not communicating with the ECM.    
3715-31 Diesel Particulate Filter Active Regeneration Inhibited Due to Permanent System Lockout - Level 3     The estimated soot load is very high. The engine may not operate properly. Factory passwords are required in order to clear this code.
