Troubleshooting Test Steps Values Results
1. Check for Codes
A. Turn the DC breaker, located in the power distribution box, to the ON position.
B. Connect Cat® Electronic Technician (ET) 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 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.
2. Monitor the Catalyst Intake Gas Temperature
A. Turn the DC breaker, located in the power distribution box, to the ON position.
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 DEF Pressure Sensor
A. Turn the DC breaker, located in the power distribution box, to the ON position.
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 8.
4. Determine the ETI Code
A. Use the ETI code recorded in Step 1 to determine the
