Troubleshooting Test Steps Values Results
1. Check the Resistance of the DEF Injector
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 DEF injector from the applicable harness.
C. Inspect the connector for damage or debris.
D. Connect Tooling A to the DEF injector. The probes must be used to prevent damage to the DEF injector connector.
E. Measure the resistance between the two probes.
DEF injector
Result: The resistance of the DEF injector measured between 10 Ohms to 14 Ohms.
Proceed to Test Step 2.
Result: The resistance of the DEF injector did not measure between 10 Ohms to 14 Ohms.
A failed DEF injector has been detected, replace the failed DEF injector. Refer to the Disassembly and Assembly, "DEF Injector and Mounting - Remove and Install".
Proceed to Test Step 8.
2. Check for a Short Circuit in the Wiring Harness
A. Disconnect the connector from the DEF injector.
B. Connect Tooling B to the DEF injector harness connector. The probes must be used to prevent damage to the connector.
C. Measure the resistance between the two probes.
The reading will measure the resistance in the wiring harness between the DEF injector connector and the DCU.
DEF injector wiring
Result: The resistance of the DEF injector wiring harness measured greater than 10K Ohms.
Connect the injector to the applicable harness.
Proceed to Test Step 3.
Result: The resistance of the DEF injector wiring harness did not measure greater than 10K Ohms.
There is a short circuit in the wiring harness between the DEF injector connector and the DCU. Repair or replace the wiring harness.
Connect the harness to the DEF injector.
Proceed to Test Step 3.
3. Perform the "DEF Dosing System Accuracy Test"
A. Use the electronic service tool to perform the "DEF Dosing System Accuracy Test". Refer to Systems Operation, Testing and Adjusting, "Aftertreatment SCR System Dosing Test" for the correct procedure.
DEF dosing
Result: The quantity collected is below 110 ml.
Proceed to Test Step
