2.7 New Event Reporting
The MT 3050 has additional event reporting not supported by other Enfora products. For general event
reporting information and for detailed information about these new events refer to the
MT 3050 AT
Command Document (GSM2374AT001)
.
2.7.1 Vehicle Identification Number (VIN)
The VIN is used as a unique identifier which is sent at first power up with heartbeat messages and with
events.
Vehicle manufacturers are responsible for defining the list of data returned,
therefore not all vehicles support retuning the Vehicle Identification Number.
2.7.2 Excessive Engine Speed (RPM)
Excessive engine speed alerts are triggered when the engine speed (in RPM) exceeds a defined RPM level
(in ¼ RPM increments) for a defined period of time in seconds (e.g., 30 seconds).
The MT 3050 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:
l
Obstructions, such as ice or mud, that may cause wheel slippage if the obstruction is not removed
from the vehicle
l
Revving the RPM while in neutral
l
Speeding or reckless driving that causes excessive RPM engine speed
