Troubleshooting Test Steps Values Results
1. Check for Codes
A. Turn the DC breaker to ON.
B. Connect Cat® Electronic Technician (Cat ET) Service Tool to the service tool connector.
C. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: A 6875–18 code is active or logged.
Record the Enhanced Troubleshooting Information (ETI) code with the event. Refer to Illustration 2 for the ETI code location.
Proceed to Test Step 2.
Result : A 7107–7 code is active or logged.
Proceed to Step 7.
2. Monitor the Catalyst Intake Gas Temperature
A. Turn the DC breaker to ON.
B. Connect Cat ET.
C. Use Cat ET to monitor the following temperature:
- "Aftertreatment #1 SCR Catalyst Intake Gas Temperature"
Temperature
Result: The "Aftertreatment #1 SCR Catalyst Intake Gas Temperature" is less than 180° C (356° F)
Proceed to Test Step 3.
Result: The "Aftertreatment #1 SCR Catalyst Intake Gas Temperature" is 180° C (356° F) or higher.
Repair: Use Cat ET to perform the following override:
- Set the "Aftertreatment #1 SCR Dosing Air Assist Valve Command Override" to the OFF position.
Proceed to Test Step 3.
3. Check the Diesel Exhaust Fluid (DEF) Pressure Sensor
A. Turn the DC breaker to ON.
B. Connect Cat ET.
C. Use Cat ET to monitor the following pressure:
- "Aftertreatment #1 DEF Dosing Pressure"
Sensor
Result: The DEF pressure sensor reads 0 20 kPa (0 3 psi).
Proceed to Test Step 4.
Result: The DEF pressure sensor does not read 0 20 kPa (0 3 psi).
Repair: Replace the DEF pressure sensor.
Proceed to Test Step 13.
4. Inspect for DEF and Air Leaks
A. Turn the DC breaker to OFF.
B. Inspect the DEF lines between the remote DEF supply and the dosing cabinet.
C. Inspect the lines and manifold inside the dosing cabinet.
D. Inspect the DEF lines between the dosing cabinet and the DEF injector.
E. Inspect the air lines for signs of leakage and ensure that lines are connected.
DEF and Air Leaks
Result: There were no DEF or air leaks.
Proceed to Test Step 5.
Result: There were DEF and/or air leaks.
Repair: Repair or replace damaged components.
Proceed to Test Step 13.
5. Determine the ETI Code
