Troubleshooting Test Steps Values Results
1. Check for Codes
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 ECM before performing any troubleshooting or clearing codes.
Codes
Result: There are no active codes.
Proceed to Test Step 2.
Result: There are active codes.
Repair: Troubleshoot any active codes before continuing with this procedure.
2. Check the Electrical Connections
A. Check for the correct installation of the ECM J1/P1 and the J2/P2 connectors. Check for correct installation of the fuel injector connectors.
Connectors
Result: There are no suspect connectors.
Proceed to Test Step 3.
Result: There are suspect connectors.
Repair: Repair connectors that are suspect or replace connectors that are suspect.
Perform the "Wiggle Test" on Cat ET.
3. Fuel Injection
C13, C15, and C18 Applications

C. Inspect the engine oil filters for ferrous material.
D. Obtain an S-O-S oil analysis. The analysis will contribute to a better understanding of oil contamination and the origin of the contamination.
Lubrication
Result: The oil passages are not blocked and the engine has proper lubrication.
Proceed to Test Step 6.
