06111-ZW1-020 Honda SEE PART DETAILS - PRI; GASKET KIT (Honda Code 7154222).

The aftertreatment identification module communicates with the engine ECM to ensure that the correct Integrated Clean Emissions Module (IGCEM) is installed.If the total operating hours of the engine are greater than 100, the aftertreatment identification module will cease to send the signal. The diagnostic codes that are listed in Table 1 will be disabled.

Troubleshooting Test Steps Values Results
1. Check for Diagnostic Codes
A. Establish communication between the electronic service tool and the Dosing Control Unit (DCU) . Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Turn the keyswitch to the ON position.
C. Look for "-2", "-8", or "-14" active or logged codes.
Diagnostic code
Result: A 5576-2 (3468-2) or 5576-14 (3468-14) diagnostic code is active.
Proceed to Test Step 9.
Result: A 5576-8 (3468-8) diagnostic code is active.
Proceed to Test Step 2.
2. Inspect Electrical Connectors and Wiring
A. Inspect the P2/J2 connector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
B. Inspect the 31-pin connector and the 40-pin connector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
C. Inspect the connector for the aftertreatment identification module. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
D. 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.
E. Check the screw for the ECM connector for the correct torque of 6 N m (53 lb in).
F. 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 or the 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.
Proceed to Test Step 4.
Result: The supply voltage is correct.
Proceed to Test Step 6.
4. Measure the Voltage to the 40-Pin Connector
A. Turn the keyswitch to the OFF position.
B. Disconnect the 40-pin connector.
C. Turn the keyswitch to the ON position.
D. Measure the voltage at the 40-pin connector on the harness between the engine and the CEM from pin 1 to pin 28.
4.84 to 5.16 VDC
Result: The voltage is within the expected range. The fault is in the harness.
Repair: Repair the faulty wiring or replace the faulty wiring.
Use the electronic service tool to verify that the repair eliminates the fault.
Result: The voltage is out of the expected range.
Reconnect the 40-pin connector. Proceed to Test Step 5.
5. Measure the Voltage to the 31-Pin Connector
A. Turn the keyswitch to the OFF position.
B. Disconnect the 31-pin connector.
C. Turn the keyswitch to the ON position.
D. Measure the voltage at the 31-pin connector on the engine harness from pin 1 to pin 28.
4.84 to 5.16 VDC
Result: 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 r
