Diagnostic Trouble Codes for the Aftertreatment Identification Module    
J1939 Code     Description     Notes    
5576-2     Aftertreatment #1 Identification Number Module: Erratic, Intermittent, or Incorrect     The Electronic Control Module (ECM) detects the following conditions:
The installed Clean Emissions Module (CEM) is not a certified match with the engine.
Diagnostic codes 5576-8 or 5576-14 are not active.
There are no active 3509 diagnostic codes.
The ECM has been powered for 2 seconds.
"This is a violation of the emissions regulations, and may result in severe fines and/or legal action if not corrected immediately." Do not operate the engine with the active fault.
Engine power is derated.    
5576-8     Aftertreatment #1 Identification Number Module: Abnormal Frequency Pulse Width or Period     The ECM detects the following conditions:
No signal is detected from the aftertreatment identification module.
There are no active 3509 diagnostic codes.
The ECM has been powered for 2 seconds.
Do not continue to operate the engine with the active fault.
Engine power is derated.    
5576-14     Aftertreatment #1 Identification Number Module: Special Instruction     The ECM detects the following conditions:
The signal from the aftertreatment identification module is invalid.
Diagnostic code 5576-8 is not active.
The ECM has been powered for 2 seconds.
Do not continue to operate the engine with the active fault.
Engine power is derated.    The aftertreatment identification module sends a digital signal to the engine ECM in order to ensure that the correct CEM is installed to the engine.If the total operating hours of the engine are greater than 25, the aftertreatment identification module will cease to send the signal. The diagnostic codes that are listed in Table 1 will be disabled.

Establish communication between the electronic service tool and the ECM.
Download the following items before performing any troubleshooting or clearing any diagnostic codes:
Warranty Report
Aftertreatment Regeneration Trigger History
Product Status Report with Histograms
Use the electronic service tool to check for active diagnostic codes.Results:
A 5576-2 diagnostic code is active. - Proceed to Test Step 9.
A 5576-8 diagnostic code is active - Proceed to Test Step 2.
A 5576-14 diagnostic code is active - Proceed to Test Step 9.Test Step 2. Inspect Electrical Connectors and Wiring
Inspect the P2/J2 connector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Inspect the 31-pin connector and the 40-pin connector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Inspect the connector for the aftertreatment identification module. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the aftertreatment identification module.
Check the screw for the ECM connector for the correct torque of 6 N m (53 lb in).
Check the harness for abrasion and pinch points from the aftertreatment identification module back to the ECM.Results:
All connectors, pins, and sockets are correctly coupled and/or inserted. The harness is free of corrosion, abrasion, and pinch points - Proceed to Test Step 3.
There is a fault with the harness and connectors - Repair: Repair the connectors or the harness and/or replace the connectors or the harness. Ensure that all of the seals are correctly in place and ensure that the connectors are correctly connected.Use the electronic service tool in order to clear all logged diagnostic codes and then verify that the repair has eliminated the fault.STOPTest Step 3. Measure the Voltage to the Aftertreatment Identification Module
Turn the keyswitch to the OFF position.
Disconnect the aftertreatment identification module from the harness.
Turn the keyswitch to the ON position.
Measure the voltage at the harness connector for the aftertreatment identification module from terminal 1 to terminal 6.Expected Result:The voltage should be 4.84 to 5.16 VDC.Results:
OK - The supply voltage is correct. Proceed to Test Step 6.
Not OK - The supply voltage is out of the nominal range. Reconnect the aftertreatment ID module. Proceed to Test Step 4.Test Step 4. Measure the Voltage to the 40-Pin Connector
Turn the keyswitch to the OFF position.
Disconnect the 40-pin connector.
Turn the keyswitch to the ON position.
Measure the voltage at the 40-pin connector on the harness between the engine and the CEM from pin 1 to pin 28.Expected Result:The voltage should be 4.84 to 5.16 VDC.Results:
OK - The voltage is within the expected range. The fault is in the CEM harness.Repair: Repair the faulty wiring or replace the faulty wiring. Use the electronic service tool to verify that the repair eliminates the fault.STOP
Not OK - The voltage is out of the expected range. Reconnect the 40-pin connector. Proceed to Test Step 5.Test Step 5. Measure the Voltage at the 31-Pin Connector
Turn the keyswitch to the OFF position.
Disconnect the 31-pin connector.
Turn the keyswitch to the ON position.
Measure the voltage at the 31-pin connector on the engine harness from pin 1 to pin 28.Expected Result:The voltage should be 4.84 to 5.16 VDC.Results:
OK - The voltage is within the expected range. The fault is in the harness between the 31-pin connector and the 40-pin connector.Repair: Repair the faulty wiring or replace the faulty wiring. Use the electronic service tool to verify that the repair eliminates the fault.STOP
Not OK - The voltage is out of the expected range. The fault is in the engine harness.Repair: Repair the faulty wiring or replace the faulty wiring. Use th
