Active Diagnostics
Active diagnostics indicate the presence of active diagnostic codes for the MSS. A diagnostic code informs the operator that a problem exists with the MSS. If the Cat service tool is available, the service tool can be used to display all active diagnostic codes. The service tool will also display codes that have been logged.Logged Diagnostics
A logged diagnostic will record problems that are intermittent for the Machine Security System. Logged diagnostics eliminate the need to duplicate problems that are intermittent. Logged diagnostics will increase the accuracy of diagnosis. The time that is required to troubleshoot a problem is reduced with the use of Diagnostics. Logged diagnostics eliminate the need for trip recorders that are used to capture intermittent diagnostic information. The control module's memory is used to store diagnostic information. When a diagnostic is detected the following information is logged:
The CID will identify the component that has failed.
The FMI will describe the problem.
