Troubleshooting Test Steps Values Results
1. Check for Diagnostic Trouble Codes
The engine coolant temperature must be greater than 0° C (32° F) before beginning this procedure.
A. Establish communication between Cat® Electronic Technician (ET) and the Electronic Control Module (ECM) . Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Wait at least 30 seconds in order for the diagnostic codes to become active.
Look for an active -13 code or for a logged -13 code.
Diagnostic Trouble Codes
Result: There is an active or there is a logged -13 code.
Proceed to Test Step 2.
2. Check for Debris
A. Turn the keyswitch to the OFF position.
B. Check the suspect sensor for debris.
C. If applicable, check the reference sensor for debris.
D. Check the sensor measurement port for blockage by debris.
E. If debris is found, clear the debris from the measurement port and replace the suspect sensor.
F. Turn the keyswitch to the ON position.
G. Check for -13 codes. Wait at least 30 seconds in order for the diagnostic codes to become active.
The 2458-13 will not activate for several hours if the ambient temperature is below 7° C (45° F) or if an active regeneration has not been performed. If troubleshooting a 2458-13 and ambient temperature is below 7° C (45° F), perform a "Manual DPF regeneration" after completing the repair to verify that the problem has been resolved.
Debris
Result: The sensor measurement port is not blocked by debris.
Proceed to Test Step 3.
Result: A -13 code is not present, return the unit to service.
Result: A -13 code is present, replace the suspect sensor. Verify that the problem is resolved.
Result: If only a 289-13 code is present, replace the reference sensor. Verify that the problem is resolved.
Result: If only a 460-13 or 5580-13 code is present, replace the reference sensor. Verify that the problem is resolved.
Result: If more than one -13 code is present and the codes have a reference sensor, replace the re
