Abnormality Display
1. Purpose and summary
When trouble occurs, a diagnostic trouble code (DTC) is displayed on the user screen.
This enables the operator to verbally communicate the trouble to the service engineer. 2. Screen

If there is no trouble, nothing at all is displayed.

The "ELEC. PROBLEM" or "CHECK ENGINE" message is displayed.
When trouble occurs, the corresponding diagnostic trouble code is displayed. For trouble in which the location is understood from the message, a code is not displayed.
