Diagnostic Trouble Codes
J1939 Codes CDL Code Code Description
(code descriptions may vary) Comments
3714-31 E992 (3) DPF Active Regeneration Inhibited Due to Temporary System Lockout The engine has been running for 10 minutes after the code was activated.
The electronic service tool "Manual Diesel Particulate Filter Regeneration" must be initiated.
3715-31 E991 (3) DPF Active Regeneration Inhibited Due to Permanent System Lockout The estimated soot load is high. The engine may not operate correctly. Factory passwords are required to clear this code.
3719-0 E995 (3) High DPF #1 Soot Loading The estimated soot load is high. Engine operation is limited to 60 second intervals when the electronic service tool is not communicating with the ECM.
3719-16 E995 (2) High DPF #1 Soot Loading 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.
Follow the troubleshooting procedure to determine the root cause of the problem. Note: Engine operation must be kept to a minimum to minimize the amount of soot that is created. Follow the troubleshooting procedure to minimize the amount of engine operation.Complete the procedure in the order in which the steps are listed.

Troubleshooting Test Steps Values Results
1. Active Codes and Logged Codes
A. Establish communication between the electronic service tool and the Electronic Control Module (ECM).
B. Look for the following codes:
1. 3719-16 (E995 (2))
2. 3719-0 (E995 (3))
3. 3715-31 E991 (3)
4. 3714-31 E992 (3)
Codes
Result: A 3715-31 (E991 (3)) code is present.
Proceed to Test Step 2.
Result: One of the following codes are present:
1. 3719-16 (E995 (2))
2. 3719-0 (E995 (3))
3. 3714-31 (E992 (3))
Proceed to Test Step 3.
2. 3715-31 (E991 (3)) Code
A. The 3715-31 (E991 (3)) code indicates that the engine has continued to run after repeated warnings and engine shutdowns. The DPF must be replaced.
DPF
Result: A 3715-31 (E991 (3)) or code is present.
Repair: Replace the DPF. Refer to the Disassembly and Assembly, "Diesel Particulate Filter - Remove and Install (Clean Emissions Module)" for the correct procedure.
After the DPF has been replaced, clear the 3715-31 (E991 (3)) code (a factory password will be necessary) and proceed to Test Step 3
