Alarms

M1 Tune provides the ability to configure user defined alarms.

When connected online to an ECU, alarms are continually monitored for change. Active alarms are presented (based on configuration) in a variety of ways:
  • Pop-up window
  • Sound effect
  • Text-to-speech announcement
  • Status bar

Alarm Behaviour Overview

An alarm must be in one of the following states:
  • Inactive (default state)
  • Active (the alarm condition is true)
  • Acknowledged (the user has acknowledged the alarm, but the condition is still true)
  • Latched (the condition is no longer true, but it has not been acknowledged by the user)

An alarm starts out in its “inactive” state. Based on the alarm condition configuration (and online ECU data acquisition) the alarm can move into the “active” state. Once active, and alarm must be acknowledged before it can renter the “inactive” state. Any alarms that are no longer active, but were not acknowledged, remain in a “latched” state (until they are acknowledged)

Alarms in an “acknowledged” state are hidden from view for a preconfigured amount of time (re-arm time) before becoming active again, unless they become inactive and active again before the re-arm time elapses.
