Troubleshooting Test Steps Values Results
1. Check that the latest available software is installed and there are no applicable Technical Information Bulletins or Special Instruction documentation released
A. Ensure that the latest software is installed on the engine ECM.
B. Ensure that the latest software is installed on the Dosing Control Unit (DCU)
If necessary, refer to Troubleshooting, "ECM Software - Install" for the correct procedure.
C. Ensure all Technical Information Bulletins and/or Special Instruction documented for the issue and/or product are reviewed and followed.
Software and Publications
Result: The latest software is not installed.
Repair: Install the latest engine ECM software and then install the latest DCU software. If necessary, refer to Troubleshooting, "ECM Software - Install" for the correct procedure.
Start the engine and wait for 2 minutes.
If the fault is cleared, return the engine to service.
If the fault is still present, proceed to Test Step 2.
Result: Applicable Technical Information Bulletin/Special Instruction publication is available.
Repair: Review and follow instructions provided in the available publication.
Result: The latest software is installed.
Proceed to Test Step 2.
2. Determine the Diagnostic Code
A. Establish communication between the electronic service tool and the engine Electronic Control Module (ECM). Refer to Troubleshooting, "Electronic Service Tools"
B. Establish communication between the electronic service tool and the Dosing Control Unit (DCU).
C. Look for active codes.
Diagnostic Trouble Codes
Result: There is an active XXXX-5 or XXXX-6 diagnostic code.
Proceed to Test Step 3.
3. Check the Battery Voltage
A. Turn the keyswitch to the OFF position.
B. Use a suitable multimeter to measure the battery voltage.
At least 12.5 V for a 12 V system
At least 25V for a 24V system
Result: The battery voltage is lower than the expected range.
Repair: Refer to Troubleshooting, Battery Problem to investigate the cause of low battery voltage.
Result: The battery voltage is within the expected range.
Proceed to Test Step 4.
4. Inspect Electrical Connectors and Wiring
A. Thoroughly inspect the 31-pin connector for the PEU. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
B. Thoroughly inspect the connectors for the coolant diverter valve and the DEF injector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
C. Perform a 45 N (10 lb) pull test on each of the wires in the 31-pin and solenoid connectors associated with the diagnostic code.
D. Ensure that the DCU connector is securely connected and locked in place.
E. Check the harness for corrosion, abrasion, and pinch points from the solenoids to the ECM.
Loose connection or damaged wire
Result: There is a fault in a connector or the wiring.
Repair: Repair any faulty connectors or replace the wiring harness. Ensure that all the seals are properly in place and ensure that the connectors are correctly coupled.
Use the electronic service tool to clear all logged diagnostic codes.
Use the electronic service tool to perform the "Aftertreatment System Functional Test" to verify that the repair eliminates 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 5.
5. Check the DEF Pressure
A. Connect to the electronic service tool. If necessary, refer to Troubleshooting, Electronic Service Tools.
B. Turn the keyswitch to the ON position. Do not start the engine.
C. Use the electronic service tool to check the "DEF Pressure" parameter. −10 kPa (−1.5 psi) to 10 kPa (1.5 psi) Result: The DEF pressure is between −10 kPa (−1.5 psi) and 10 kPa (1.5 psi).
Repair: Start the engine and allow the DEF system to prime.
Stop the engine and wait for the wait-to disconnect lamp to switch off.
Turn the keyswitch to the ON position. Check for an active 4334–20 or 4334–21 diagnostic code.
If the diagnostic code is no longer active, return the engine to service.
If the diagnostic code is still active, proceed to Test Step 6.
6. Replace the Pump and Electronics Unit (PEU)
Note: The PEU is a non-serviceable unit. If a fault is suspected in the PEU, the unit must be replaced.
A. Turn the keyswitch to the OFF position. Wait until the wait-to-disconnect lamp switches off.
B. Isolate the power to the DCU.
C. Replace the PEU.
Diagnostic Trouble Codes
Result: The PEU was replaced.
Proceed to Test Step 7.
7. Perform a DEF Dosing System Verification Test
A. Turn the keyswitch to the "ON" position. Do not start the engine.
B. Connect to the "Diesel Exhaust Fluid Controller #1 ECM" using the electronic service tool.
C. Perform the "DEF Dosing System Verification Test" .
Diagnostic codes
Result: The code did not return.
Return the unit to service.
Result: The code returned.
