Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. 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.
Proceed to Test Step 2.
2. Check for Incorrect Monitoring System Parameters
A. Connect Cat ET.
B. Use Cat ET to verify that the correct parameters are being used.
- Exhaust temperature module
- Exhaust port temperatures
Parameters
Result: The parameters are correct.
Proceed to Test Step 3.
Result: The parameters are not correct.
Repair: Input the correct parameters. Refer to Troubleshooting, "Event Codes" for additional information.
If the problem is not resolved, proceed to Test Step 3.
3. Check for Inlet Air Restriction
