1.3 On-Board Diagnostics Overview
An On-Board Diagnostics (OBD) system controls engine functions and serves as the diagnostic control
network of the vehicle. All cars built and sold in the United States since 1996 must be equipped with the
newer OBDII system. The Enfora MT 3000 connects to a vehicle's OBDII port and monitors the OBDII
system using a variety of communication protocols.
The MT 3000 can be configured to provide notification messages based on engine rpm, low fuel or battery,
or other events monitored by the OBDII system in addition to events triggered by the device's
accelerometer or GPS information.
Some vehicles are not compatible with the MT 3000. If the vehicle is not compatible
with the parameters the MT 3000 requires, functionality my be limited, problematic
or unavailable.
The SAE (Society of Automobile Engineers) 1979 standard defines the method for requesting diagnostics
data and a list of standard parameters from the engine control unit.
Compliance to this standard is the responsibility of the vehicle manufacturer, therefore Enfora cannot
guarantee performance of the MT 3000 with every vehicle.
The following are some of the OBDII parameters monitored by the Enfora MT 3000 and triggered as alerts
when so configured:
l Vehicle Identification Number (VIN)
l Excessive engine speed (RPM)
l Vehicle speed
l Vehicle battery voltage (low battery warning)
l Check engine light (MIL alert)
l Odometer (trip distance)
l Idle time
l Low fuel
