the Engine Diagnostics Menu feature. Refer to Chapter 59--130 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
yourengine. Refer to the appropriate Cummins Troubleshooting Manual or your Cummins dealer for additional information on isolating and repairing potential
or existing problems.

The first column of the following chart indicates the
