Trouble Codes Are Displayed

A maximum of 3 trouble codes are displayed in order of occurrence.

• If a particular trouble code is not properly stored in memory (due to a drop in ABSCM & H/U 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.
