1. Check for Codes
Note: 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 ECM .
B. Download the "Warranty Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
Wait at least 30 seconds in order for the diagnostic
