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 Damaged or Plugged Air Filter Elements
Note: For optimum operation, replace the air filter elements when the inlet air restriction reaches 2.5 kPa (10 inch of H2O). The maximum allowable inlet air restriction is 3.75 kPa (15 inch of H2O).
Air Filter Element
Result: The air filter element is not plugged and the piping is not restricted.
Proceed to Test Step 3.
Result: The air filter element is plugged or the piping is restricted.
Repair: Clean or replace the air filter element.
If problem is not resolved, proceed to Test Step 3.
3. Check the Enclosure
A. Check that the engine has been installed in an enclosure that is sufficiently ventilated.
Enclosure
Result: The engine enclosure is sufficiently ventilated.
Proceed to Test Step 4.
Result: The engine enclosure is not sufficiently ventilated.
Repair: Repair the ventilation for the enclosure.
If problem is not resolved, proceed to Test Step 4.
4. Check the Inlet Restriction Pressure Sensor
A. Connect Cat ET.
B. Use Cat ET to monitor the following temperature:
- Inlet restriction pressure
Sensor
Result: The inlet restriction pressure sensor is OK.
Proceed to Test Step 4.
Repair: Repair or replace the circuit component.
Result: The inlet restriction pressure sensor is NOT OK.
Repair: Replace the sensor.
If problem is not resolved, proceed to Test Step 5.
5. Inspect the Electrical Connectors and the Wiring
A. Turn the main disconnect switch to the OFF position.
B. Thoroughly inspect the connectors. Refer to Troubleshooting, "Electrical Connectors-Inspect" for additional information.
C. Perform a 45 N (10 lb) pull test on the connector wires.
D. Check the harness for abrasions and pinch points.
Connectors and Wiring
Result: There is a problem with the connectors and/or wiring.
Repair: Repair or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are coupled.
Verify that the repair eliminated the problem.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
