The final “eXpress Diagnostic Coverage and Remediation Chart” produces a detailed analysis of how well each failure can be detected and isolated by the diagnostics. When generated for a diagnostic study that represents the operational diagnostics for a system or device, then this chart can be used to supplement information presented in the eXpress Fault Signature Analysis Chart. When generated using a diagnostic study representing maintenance or “troubleshooting” diagnostics, however, this chart becomes a valuable indication of which failures will be effectively diagnosed during maintenance.
