Diagnostic Trouble Codes for the Aftertreatment Identification Module
J1939 Code CDL Code Code Description
(code descriptions may vary) Comments
5576-2 3468-2 Aftertreatment #1 Identification : 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 situation 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 3468-8 Aftertreatment #1 Identification : 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. The aftertreatment identification module communicates with the engine ECM to ensure that the correct Clean Emissions Module (CEM) is installed.If a valid signal is seen from the aftertreatment identification module for a continuous 25 hours, the ECM will no longer look for the information from the module. The diagnostic codes that are listed in Table 1 will be disabled.If the aftertreatment identification module is replaced during the initial 25 hours, the ECM may look for the signal for up to 100 hours.

Troubleshooting Test Steps Values Results
1. Check for Diagnostic Codes
A. Establish communication between the electronic service tool and the Electronic Control Module (ECM) . Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Turn the keyswitch to the ON position.
C. Look for "-2" or "-8" active or logged codes.
Diagnostic code
Result: A 5576-2 or 3468-2 diagnostic code is active.
Proceed to Test Step 6.
Result: A 5576-8 or 3468-8 diagnostic code is active.
Proceed to Test Step 2.
2. Inspect Electrical Connectors and Wiring
A. Inspect the P1/J1 connector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
B. Inspect the connector for the aftertreatment identification module. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
C. 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.
D. Check the screw for the ECM connector for the correct torque of 6 N m (53 lb in).
E. Check the harness for abrasion and pinch points from the aftertreatment identification module back to the ECM.
Connectors and wiring
Result: 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 the seals are correctly in place and ensure that the connectors are correctly connected.
Use the electronic service tool to clear all logged diagnostic codes and then verify that the repair has eliminated the fault.
Result: 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.
3. Measure the Voltage to the Aftertreatment Identification Module
A. Turn the keyswitch to the OFF position.
B. Disconnect the aftertreatment identification module from the harness.
C. Turn the keyswitch to the ON position.
D. Measure the voltage at the harness connector for the aftertreatment identification module from terminal 1 to terminal 6.
4.84 to 5.16 VDC.
Result: The supply voltage is out of the nominal range.
Repair: Replace the harness.
Use the electronic service tool to verify that the repair eliminates the fault.
Result: The supply voltage is correct.
Proceed to Test Step 4.
4. Check the Signal Wire for an Open Circuit
A. Turn the keyswitch to the OFF position.
B. Disconnect the connector for the aftertreatment ID module. Disconnect the P1 connector on the engine ECM.
C. Check the resistance between P1:70 and terminal 3 on the harness connector for the aftertreatment identification module.
Less than 2.0 Ohms
Result: The measured resistance is more than 2.0 Ohms.
Repair: Replace the harness.
Use the electronic service tool to verify that the repair eliminates the fault.
Result: The measured resistance is less than 2.0 Ohms
Proceed to Test Step 5.
5. Check the Signal Wire for a Short Circuit
A. Turn the keyswitch to the OFF position.
B. Measure the resistance between P1:70 and all other terminals on the P1 connector.
Greater than 100 Ohms
Result: At least one of the resistance measurements is less than 100 Ohms.
Repair: Replace the wiring between the aftertreatment identification module and the ECM.
Use the electronic service tool to verify that the repair eliminates the fault.
Result: All measured resistances are greater than 100 Ohms.
Proceed to Test Step 6.
6. Manually Enter the "Aftertreatment Identification Information"
A. Record the "CEM serial number" and the "configuration group" from the CEM Identification Plate. The identification plate is on the end cover of the CEM.
B. Contact the Dealer Solutions Network (DSN) for a list of approved RF and CEM configurations for the engine.
C. Verify that the CEM is a certified match with the engine.
D. Establish communication between the electronic service tool and the ECM . If necessary, refer to Troubleshooting, "Electronic Service Tools".
E. Navigate to the "Aftertreatment Configuration" page.
F. Program the "Factory Installed Aftertreatment #1 Identification Number" with the serial number from the CEM Identification Plate.
G. Program the "DPF #1 Soot Loading Sensing System Configuration Code"
