Excessive Engine Speed (Rpm); Vehicle Speed; Vehicle Battery Voltage (Low Battery Warning) - Enfora MT 3000 User Manual

Vehicle manufacturers are responsible for defining the list of data returned,
therefore not all vehicles support retuning the Vehicle Identification Number.

Excessive Engine Speed (RPM)

Excessive engine speed alerts are triggered when the engine speed (in RPM) exceed a defined RPM level
(in ¼ RPM increments) for a defined period of time in seconds (e.g. 30 seconds).
The MT 3000 has three definable thresholds.
Unnecessary wear and tear on the powertrain control module (PCM) may occur if constant or frequent
excessive engine speed is reported. The excessive engine speed event may be caused by one of the
following situations:
There are obstructions (ice, mud, etc...) causing wheel slippage that must be cleared from the
l
vehicle
The driver is revving the RPM while in neutral
l
The driver is driving in such a way that the RPM engine speed is deemed excessive, such as speeding
l
AT$OBDEES=1,16000,3,30
Sets excessive engine speed threshold 1 to 4000 RPM, if exceeded for 3 seconds, trigger input event. This
event will clear once engine RPM is below 4000 for 30 seconds.

Vehicle Speed

If configured for vehicle speed alerts and the vehicle moves faster than one of the three configurable
thresholds (e.g. 70 MPH), then a vehicle speed alert is triggered.
AT$OBDSPD=1,112,10,104
Sets Vehicle Speed Threshold 1 to 112 KPH (~70MPH). If Threshold excededed for 10 seconds trigger input
event. This event will clear when vehicle speed is reduced to 104KPH (~65MPH).

Vehicle Battery Voltage (Low Battery Warning)

The vehicle battery voltage alert is triggered when the vehicle's battery is reported to be below a threshold
(e.g. 10.7 V) for a user-defined period of time in seconds (e.g. 300 seconds).
AT$OBDLBL=10800,300,300
