1 ENGINE DIAGNOSTICS GROUP 105 CUMMINS ENGINE DIAGNOSTIC CODES 1 INTRODUCTION TROUBLESHOOTING CODES INTRODUCTION. This group provides information on the engine fault codes that could potentially appear on the LCD display at the center of your electronic dash when using the Engine Diagnostics Menu feature. Refer to Chapter in your service or operator manual for instructions on reading and clearing fault codes. These codes can be used to help isolate the problem area in your engine. Refer to the appropriate Cummins Troubleshooting Manual or your Cummins dealer for additional information on isolating and repairing potential or existing problems. 2 TROUBLESHOOTING CODES. (AS OF 2/15/06) The first column of the following chart indicates the Suspect Parameter Number (SPN).
