Troubleshooting Test Steps Values Results
1. Check the DEF Pump Pressure Sensor Supply Circuit for Excessive Voltage
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 Pump Electronic Tank Unit (PETU) harness from the DEF pump.
C. Verify that the harness connector is free of debris, free of corrosion, and securely connected.
D. Turn the keyswitch ON.
E. Measure the voltage between the 5V SUPPLY (Terminal 2) at the DEF pump connector and a known good ground source.
Supply voltage
Result: The voltage is greater than 5V.
Proceed to Test Step 3.
Result: The voltage is 5V or less.
Proceed to Test Step 2.
2. Check the DEF Pump Pressure Sensor Supply for a Short Circuit to Ground
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 DCU.
B. Disconnect the PETU wiring harness from the DEF pump.
C. Disconnect the 86 pin connector from the DCU.
D. Connect the 398-5056 Break-out Connector to the DEF pump connector.
The 398-5056 Break-out Connector must be used to prevent damage to the DEF pump connector.
E. Measure the resistance between the 5V SUPPLY (Terminal 2 at the DEF pump connector) and a known good ground source.
Short circuit
Result: There was more than 100K ohms of resistance between the 5V SUPPLY and a ground source.
Proceed to Test Step 4.
Result: There was less than 100K ohms of resistance between the 5V SUPPLY and a ground source.
A short circuit to ground has been detected. Repair or replace the wiring harness.
Proceed to Test Step 4.
3. Check the DEF Pump Supply for a Pin-to Pin Short 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 DCU.
B. Disconnect the PETU wiring harness from the DEF pump.
C. Disconnect the 86 pin connector from the DCU.
D. Connect the 398-5063 Break-out Connector to the DCU connector.
The 398-5063 Break-out Connector must be used to prevent damage to the DCU connector.
E. Measure the resistance between the 5V SUPPLY (Terminal 19 at the DCU connector) and all other pins in the DCU 86 pin connector.
Short circuit
Result: There was more than 100K ohms of resistance between the 5V SUPPLY and all other pins in the DEF pump connector.
Proceed to Test Step 4.
Result: There was less than 100K ohms of resistance between the 5V Supply and all other pins in the DEF pump connector.
There is a problem in the wiring harness. Repair or replace the wiring harness.
Proceed to Test Step 4.
4. 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 Cat ET.
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.
A failed DEF pump has been detected. Replace the DEF pump.
Perform the DEF Dosing Verification Test to verify that the issue has been resolved.
Complete the procedure in the order in which the steps are listed.
