7.2.1 Alarm, and Error messages
When an error occurs, the DLC flashes Alarm and Error messages alternately with the standard display.
If the error is catastrophic (e.g.; Tachometer Failure), the catastrophic error message will remain
displayed until the problem is repaired.
The following table gives an example of these messages and when you can expect them to be
displayed.
