Diagnostic Code Display
- System will begin displaying codes (if any are stored). See Figure. The first character of the code is a letter that indicates which system the code applies to. See SYSTEM LETTER CODE INTERPRETATION table.
- The fifth character of the code is the letter "C" or "H". "C" stands for current code. Current means the fault currently exists (like a hard code), and the fault was present the last time the diagnostic test was run. "H" stands for history code. History means the fault does not currently exist, but existed before (like an intermittent code), and was not present the last time the diagnostic test was run.
- If no codes are present for a system, a NO X CODE message will be displayed (with X being the system displayed). If the communication line for a system is not operating, a NO X DATA message will be displayed, indicating that the IPC could not communicate with that system.
