Function Code FB: Mode (Trouble Codes Are Displayed)

NOTE:
- If a particular trouble code is not properly stored in memory (due to a drop in ABSCM power supply, etc.) when a problem occurs, the trouble code, followed by a question mark "?", appears on the select monitor display. This shows it may be an unreliable reading.





- * a * refers to the troubles in order of occurrence (NEW, MID and OLD).
