How Idle is Calculated
Once a vehicle has been stationary, with the key on, for a particular period of time (standard is 120 seconds), a stop event is triggered and the unit begins to calculate idle
Note: A vehicle sitting at rest with the engine off but key at the ACC (Accessory position) to perhaps operate the car stereo, will not be recording idle time.
| Event | Time being recorded as Idle | Event to trigger end of idle time |
|---|---|---|

| Moving From Stopped  |

|  | Moving From Stopped

The idle calculation does not include the 120 seconds used to trigger a stop event.
