Use this procedure in order to troubleshoot excessive soot in the Diesel Particulate Filter (DPF). Also use this procedure if one of the following event codes are active. Refer to Troubleshooting, "Event Codes" for information about event codes. For information on the engine monitoring system, refer to Troubleshooting, "Engine Monitoring System".Note: Certain systems will display multiple codes for troubleshooting. These "Associated Codes" must be used in order to troubleshoot the system effectively. Refer to Troubleshooting, "General Information" for additional information.Note: Refer to Troubleshooting, "Cat ET Service Features" for information about service features.The Engine Control Module (ECM) maintains an estimate of the soot load in the Diesel Particulate Filter (DPF). The estimate is based on the engine operating conditions. If the ECM estimates that the soot load is excessive, the ECM activates the applicable code.Note: After the regeneration is complete and soot loading is reduced to 0%, the active soot loading code will not become logged or cleared for 5 minutes.

J1939 Codes and Description CDL Code and Description Comments
3719-16
High DPF #1 Soot Loading 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 or maximum rpm will be lowered as the soot load increases.
3719-0
High DPF #1 Soot Loading E995 (3)
High DPF #1 Soot Loading The estimated soot load is high. Engine operation is limited to 60 second intervals when the Caterpillar Electronic Technician (ET) is not communicating with the ECM.
3715-31
DPF Active Regeneration Inhibited Due to Permanent System Lockout E991 (3)
DPF 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.
3714-31
DPF Active Regeneration Inhibited Due to Temporary System Lockout E992 (3)
DPF Active Regeneration Inhibited Due to Temporary System Lockout The engine has been running for10 minutes after the E995 (3) code was activated.
The Cat ET Manual Diesel Particulate Filter Regeneration must be initiated.

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Establish communication between Cat® Electronic Technician (ET) and the Electronic Control Module (ECM).
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Look for the following codes:
1. E995 (2) or 3719-16
2. E995 (3) or 3719-0
3. E991 (3) or 3715-31
4. E992 (3) or 3714-31
Codes
Result: A E991 (3) or 3715-31 code is present.
Proceed to Test Step 2.
Result: One of the following codes are present:
1. E995 (2) or 3719-16
2. E995 (3) or 3719-0
3. E992 (3) or 3714-31
Proceed to Test Step 3.
2. E991 (3) or 3715-31 code
A. The E991 (3) or 3715-31 code indicates that the engine has
