Troubleshooting Test Steps Values Results
1. Inspect Electrical Connectors and Wiring
A. Inspect the 86-pin DCU connector.
B. Inspect the connector for the DEF pump.
C. Perform a 45 N (10 lb) pull test on each of the wires in the DCU connector and the connector for the DEF pump.
D. Check all 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. 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. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Establish communication between the electronic service tool and the Dosing Control Unit (DCU) .
D. Check for active or logged codes.
Diagnostic trouble codes
Result: There is an active or logged 4334-3, 3090-3, 4334-4 or 3090-4 diagnostic code.
Proceed to Test Step 3.
3. Check for an Open Circuit in the Pump Electronic Tank Unit (PETU) Wiring Harness for the DEF Pump Pressure Sensor Circuit
A. Turn the keyswitch to the OFF position for 2 minutes. The keyswitch must be OFF for 2 minutes to allow the DEF pump to purge, reset the code, and reset the Diesel Exhaust Fluid Controller (DCU).
B. Disconnect the PETU wiring harness from the DEF pump and the DCU.
C. Connect the 398-5063 Break-out Connector to the DCU connector. Connect the 398-5056 Break-out Connector to the DEF pump connector.
Note: The connectors must be used to prevent damage to the DCU and DEF pump connector.
D. Measure the resistance between terminal 2 (SUPPLY) on the DEF pump connector and terminal 19 (SUPPLY) on the 86-pin DCU connector.
E. Measure the resistance between terminal 3 (SIGNAL) on the DEF pump connector and terminal 17 (SIGNAL) on the 86-pin DCU connector.
F. Measure the resistance between terminal 4 (GROUND) on the DEF pump connector and terminal 18 (GROUND) on the 86-pin DCU connector.
Less than 5 Ohms
Result: All resistance measurements are less than 5 Ohms.
Proceed to Test Step 4.
Result: At least one of the resistance measurements is greater than 5 Ohms. There is an open in the harness.
Repair: Repair the wiring or replace the harness.
Verify that the fault is resolved.
Proceed to Test Step 6.
4. Check for Short Circuits in the PETU Wiring Harness for the DEF Pump Pressure Sensor Circuit
A. Turn the keyswitch to the "OFF" position.
B. Disconnect the PETU wiring harness from the DEF pump and the DCU.
C. Connect the 398-5056 Break-out Connector to the DEF pump connector.
Note: The connector must be used to prevent damage to the DEF pump connector.
D. Measure the resistance between terminal 2 (SUPPLY) on the DEF pump connector and a known good chassis ground.
E. Measure the resistance between terminal 3 (SIGNAL) on the DEF pump connector and a known good chassis ground.
F. Measure the resistance between terminal 4 (GROUND) on the DEF pump connector and a known good chassis ground.
Greater than 100k Ohms
Result: All resistance measurements are greater than 100k Ohms.
Proceed to Test Step 5.
Result: At least one of the resistance measurements is less than 100k Ohms. There is a short circuit in the harness.
Repair: Repair the wiring or replace the harness.
Verify that the fault is resolved.
Proceed to Test Step 6.
5. Check for Short Circuits in the PETU Wiring Harness for the DEF Pump Pressure Sensor Circuit
A. Turn the keyswitch to the "OFF" position.
B. Disconnect the PETU wiring harness from the DEF pump and the DCU.
C. Connect the 398-5063 Break-out Connector to the DCU connector.
Note: The 398-5063 Break-out Connector must be used to prevent damage to the DCU connector.
D. Measure the resistance between terminal 19 (SUPPLY) of the DCU connector and all other pins in the 86-pin DCU harness connector.
E. Measure the resistance between terminal 17 (SIGNAL) of the DCU connector and all other pins in the 86-pin DCU harness connector.
F. Measure the resistance between terminal 18 (GROUND) of the DCU connector and all other pins in the 86-pin DCU harness connector.
Greater than 100k Ohms
Result: All the resistance measurements are greater than 100k Ohms. A failed DEF pump has been detected.
Repair: Replace the DEF pump.
Proceed to Test Step 6.
Result: At le
