Diagnostic Trouble Codes
J1939 Code and Description Conditions that Generate the Code System Response
411-15 Engine Exhaust Gas Recirculation Differential Pressure : High - least severe (1) The Electronic Control Module (ECM) detects an abnormally high reading from the NRS differential pressure sensor. The code is logged.
411-17 Engine Exhaust Gas Recirculation Differential Pressure : Low - least severe (1) The ECM detects an abnormally low reading from the NRS differential pressure sensor. The code is logged.
2659-15 Engine Exhaust Gas Recirculation (EGR) Mass Flow Rate : High - least severe (1) The ECM has detected a high flow rate through the NRS. The code is logged.
2659-16 Engine Exhaust Gas Recirculation (EGR) Mass Flow Rate : High - moderate severity (2) The ECM has detected a high flow rate through the NRS. The code is logged.
2659-17 Engine Exhaust Gas Recirculation (EGR) Mass Flow Rate : Low - least severe (1) The Electronic Control Module (ECM) detects a lower than desired flow rate through the NRS The code is logged.
2791-5 Engine Exhaust Gas Recirculation (EGR) Valve Control : Current Below Normal The Electronic Control Module (ECM) detects a low current in the circuit for the NRS actuator solenoid. The code is logged.
2791-6 Engine Exhaust Gas Recirculation (EGR) Valve Control : Current Above Normal The ECM detects a high current in the circuit for the NRS actuator solenoid. The code is logged.
3358-16 Engine Exhaust Gas Recirculation Inlet Pressure : High - moderate severity (2) The ECM detects an abnormally high inlet pressure to the NRS. The code is logged.

Location of the NRS actuator solenoid
Note: Exhaust Gas Recirculation (EGR) is a term used to describe the recirculation of exhaust gas through the engine as a means to reduce NOX emissions. Caterpillar has elected to refer to this system as the NOX Reduction System (NRS). Diagnostic codes are regulated by Society of Automotive Engineers (SAE). The diagnostic codes use the EGR nomenclature.

Schematic for the NRS actuator solenoid
Test Step 1. PERFORM PRESSURE SENSOR CALIBRATION
Connect Cat ET to the service tool connector.
Turn the keyswitch to the ON position. Allow 30 seconds for a calibration of the engine pressure sensors to be performed by the ECM.
Check for diagnostic trouble codes that are associated with the sensor calibration. Check for the following codes:
411-13 Engine Exhaust Gas Recirculation Differential Pressure : Calibration Required
3563-13 Engine Intake Manifold #1 Absolute Pressure : Calibration Required
Turn the keyswitch to the OFF position.Results:
No Active -13 Codes - There are no active -13 codes currently. Proceed to Test Step 2.
Active 411-13 or 3563-13 Code - Either a 411-13, or a 3563-13 is active.Repair: Perform another calibration attempt, follow these instructions closely:
Turn the keyswitch to the OFF position. Allow the keyswitch to remain in the OFF position for ten minutes.
Turn the keyswitch to the ON position. Allow 30 seconds for the ECM to attempt a calibration of the sensor.
Turn the keyswitch to the OFF position. Allow the keyswitch to remain in the OFF position for 30 seconds.Note: Do not use the battery disconnect switch to power-down the ECM. Ensure that the unswitched battery power to the ECM remains on so that the calibration data can be saved to internal memory.
Turn the keyswitch to the ON position. Check for diagnostic trouble codes that are associated with the sensor calibration. Check for the following codes:
411-13 Engine Exhaust Gas Recirculation Differential Pressure : Calibration Required
3563-13 Intake Manifold Pressure Sensor : Calibration RequiredIf the original code is still active, replace the appropriate sensor. Check for the recurrence of the diagnostic codes to verify that the problem is resolved.STOPTest Step 2. CHECK FOR ASSOCIATED CODES
Establish communication between Caterpillar Electronic Technician (ET) and the engine ECM. Refer to Troubleshooting, "Electronic Service Tools" for details.
Download the "Product Summary Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
Determine if an associated code is active or logged. Table 2 lists the associated diagnostic code.
Table 2
Associated Code
J1939 Code Description
412-15 Engine Exhaust Gas Recirculation Temperature : High - least severe (1)
412-16 Engine Exhaust Gas Recirculation Temperature : High - moderate severity (2) Expected Result:There are no associated codes that are active or logged.Results:
OK - No associated codes are active or logged. Proceed to Test Step 3.
Not OK - There are associated codes that are active or logged.Repair: Troubleshoot associated codes prior to continuing with this procedure. Refer to Troubleshooting, "Diagnostic Trouble Codes" to troubleshoot the associated diagnostic code.STOPTest Step 3. CHECK FOR ACTIVE DIAGNOSTIC TROUBLE CODES
Establish a connection between the engine ECM and Cat ET.
Turn the keyswitch to the ON position.
Monitor the active diagnostic code screen on Cat ET. Check and record any active diagnostic codes.Note: Allow 30 seconds for the codes to become active.Check for the following codes:
411-15
411-17
2659-15
2659-16
2659-17
2791-5
2791-6
3358-16Results:
Active 2791-5 - There is a low current in the circuit that is for the solenoid for the valve actuator. Proceed to Test Step 13.
Active 2791-6 - There is a high current in the circuit that is for the solenoid for the valve actuator. Proceed to Test Step 12.
Active or Logged 3358-16 - Proceed to Test Step 6.
Active or Logged 2659-17 and 3358-16 - Proceed to Test Step 6.
Active or Logged 411-15 and/or 411-17 and/or 3358-16 - Proceed to Test Step 8.
Active or Logged 2659-15 and/or 2659-16 and/or 2659-17 - Proceed to Test Step 4.Test Step 4. INSPECT ALL EXHAUST PIPING FOR THE NRS FOR LEAKAGE
