Troubleshooting Test Steps Values Results
1. Inspect Electrical Connectors and Wiring
A. Inspect the P2/J2 ECM connector.
B. Inspect the connector for the DEF pump.
C. Perform a 30 N (6.7 lb) pull test on each of the wires in the ECM connector and the connector for the DEF pump.
D. Check all of the wiring associated with the DEF pump for abrasions and pinch points.
Damaged wire or connector
Result: A damaged wire or damaged connector was not found.
Proceed to Test Step 2.
Result: A damaged wire or damaged connector was found.
Repair: Repair the damaged wire or the damaged connector.
Use the electronic service tool to clear all logged diagnostic codes. Verify that the repair eliminates the fault.
2. Check for Active Diagnostic Codes
A. Establish communication between the electronic service tool and the ECM. Refer to Troubleshooting, "Electronic Service Tools"
B. Check for active or logged codes.
Diagnostic Trouble Codes
Result: There is an active or logged , 4334-3 or 4334-4 diagnostic code.
Proceed to Test Step 3.
3. Check the Sensor Supply and Ground Wiring
A. Turn the keyswitch to the OFF position for 2 minutes.
B. Disconnect the DEF pump connector.
C. Turn the keyswitch to the OFF position.
D. Use a multimeter to measure the voltage between terminal 8 and terminal 10 on the harness connector for the DEF pump.
E. Turn the keyswitch to the OFF position.
4.9 V to 5.1 V
Result: The measured voltage is not within the expected range.
The fault is in the wiring between the DEF pump and the P2 ECM connector.
Repair: Replace the faulty wiring.
Proceed to Test Step 5.
Result: The measured voltage is within the expected range.
Proceed to Test Step 4.
4. Check the Voltage on the Sensor Signal Wiring
A. Turn the keyswitch to the OFF position for 2 minutes.
B. Disconnect the connector for the DEF pump.
C. Turn the keyswitch to the ON position.
D. Use a multimeter to measure the voltage between terminal 8 and terminal 9 on the harness connector for the DEF pump.
E. Turn the keyswitch to the OFF position.
4.9 V to 5.1 V
Result: The measured voltage is not within the expected range.
The fault is in the wiring between the DEF pump and the P2 ECM connector.
Repair: Replace the faulty wiring.
Proceed to Test Step 5.
Result: The measured voltage is within the expected range.
Repair: Install a replacement DEF pump module.
Use the electronic service tool to clear all logged diagnostic codes and verify that the repair eliminates the fault.
Proceed to Test Step 5.
5. Perform a DEF Dosing System Verification Test
A. Start the engine.
B. Use the electronic service tool to perform the "DEF Dosing System Verification Test".
Diagnostic codes
Result: The diagnostic code did not return.
Return the unit to service.
Result: The diagnostic code returned.
