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:
Vehicle Identification Number (VIN)
Excessive engine speed (RPM)
Vehicle speed
Vehicle battery voltage (low battery warning)
Check engine light (MIL alert)
Odometer (trip distance)
Idle time
Low fuel
-2-
The MT 3000 supports the following standard OBDII protocols:
J1850 PWM
J1850 VPW
ISO-9141-2
ISO-14230 KWP2000
ISO-15765 CAN
Some vehicles only support a subset of these protocols, in these cases functionality of
the MT 3000 will be limited.

4 Software Features
AT Commands Over SMS
A user can send AT commands to the MT 3000 via SMS. Please refer to Enfora Application Note
GSM0308AN001 - Enabler IIIG AT Commands Over SMS.
Store/Transmit Event Data
The user can configure the MT 3000 to store event-generated data in its internal memory, to be sent over
the air to a remote server. This feature can be enabled or disabled using the AT$MSGLOGEN command.
“Total Number of Unread Messages” is decremented if an unread message is read via the AT$MSGLOGRD
command.
Example: Assume there are 50 unread messages in the GPRS queue and the total number of messages in
GPRS queue is 100. This means that the first 50 messages have been read while the last 50 messages have
not been read. If a user sends AT$GPSLOGRD=0,1,51 then the total number of unread messages drops
down to 49 after successful transmission of that message. However, if a user sends AT$GPSLOGRD=0,1,99
then the total number of unread messages still remains at 50 – that message is transmitted to the remote
server.
A user can also read a message that has already been read from the memory by passing in the appropriate
starting index number.
Synchronize RTC Time with GPS Time
The Real Time Clock ("RTC") is synchronized with GPS time automatically every time the device is powered
up and first acquires valid GPS data. Additionally, the RTC time is synched with GPS time every time the
GPS time rolls over from 23:59:59 to 00:00:01.
4.1 New Event Reporting
The MT 3000 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 3000 AT
Command Document (GSM2374AT001).
Vehicle Identification Number (VIN)
The VIN is used as a unique identifier, sent at first power up, with heartbeat messages, and with events.
- 17 -
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
vehicle
The driver is revving the RPM while in neutral
The driver is driving in such a way that the RPM engine speed is deemed excessive, such as speeding
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$OBDLBL=10800,300,300
- 18 -
Sets low battery threshold to 10.8volts. If below this threshold for 300 seconds (5 minutes) trigger the input
event. restoring voltage abovethe threshold for 300secods (5 minutes) will clear this event.
Check Engine Light (MIL Alert)
When the vehicle “Check Engine” light illuminates, this indicates a vehicle issue that requires attention for
diagnosis and/or repair. This is also known as a Malfunction Indicator Light (MIL). When a MIL issue is
detected through the OBDII protocol, an alert is sent from the device if the device is configured to do so.
Trip Odometer Reporting
Trip odometer reporting provides the odometer miles accumulated from ignition on to ignition off, which
is considered a “trip”.
NOTE: Ignition events are not yet detected on hybrid or electric vehicles.
Idle Time Reporting
Idle time event is triggered when the vehicle’s engine is running without the vehicle moving (i.e. velocity
less than 2 MPH) for a defined period of time in seconds (e.g. 300 seconds).
The alert is cleared when the vehicle speed exceeds another speed and time threshold.
Both the violation and clearing of the alert are reported if configured.
AT$OBDLBL=10800,300,300
Sets low battery threshold to 10.8volts. If below this threshold for 300 seconds (5 minutes) trigger the input
event. restoring voltage abovethe threshold for 300secods (5 minutes) will clear this event.
Low Fuel Alert
The low fuel alert triggers when the vehicle’s fuel level falls below a defined threshold in percent (e.g.
12%) for a defined period of time in seconds (e.g. 60 seconds).
Rapid Acceleration
Rapid acceleration events can be triggered when one of three available vehicle speed thresholds are
exceeded as determined by the accelerometer in milli-Gs (e.g. 0.75) for a defined period of time in
seconds (e.g. 30 seconds).
AT$OBDACL=1,200,1,30
- 19 -
Sets Rapid accel threshold 1 to .2Gs. If this threshold is exceeded for 1 second, trigger the input event. This
event will clear in 30 seconds below this treshold.
Sudden Deceleration (Harsh Braking)
Rapid deceleration events can be triggered when one of three available vehicle speed thresholds are
exceeded as determined by the accelerometer in milli-Gs (e.g. 1.0) for a defined period of time in seconds
(30 seconds).
AT$OBDDCL=1,.500,1,3
Sets Rapid decel threshold 1 to .5Gs. If this threshold is exceeded for 1 second, trigger the input event. This
event will clear in 30 seconds below this treshold.
Motion Detection
Motion alerts for vehicles can be configured to communicate that a vehicle is being towed. Motion
detection based on measuring movement via the accelerometer occurs when the vehicle ignition is off,
and the vehicle is stationary.
A motion alert is triggered when motion defined in milli-Gs is detected for a defined period of time.
OBDII Basic Event Data
Four additional data items can be included with event messages:
VIN
Firmware version ($PKG)
OBD Protocol (i.e. J1850 PWM)
Cellular signal strength (RSSI)

5 Installation
5.1 Inserting the SIM
Insert the SIM per the following procedure:
Note: The SIM card is not provided with the MT 3000 device. The SIM must be
obtained from the GSM/GPRS service provider and must be provisioned by the
operator for data. Always take care to protect the SIM. Without the SIM installed,
MT 3000 modem is not able to communicate on the network.
1. Using the correct tool, carefully remove the device cover to access the internal SIM holder.
2. Insert the SIM into the SIM holder of the MT 3000.
3. Replace the cover.
Figure: 17 - Internal SIM Holder
- 21 -
5.2 Device Installation
Instructions provided in this section describe the hardware installation of the MT 3000 device. To install
the MT 3000 in a vehicle, follow these steps:
Locate the OBDII socket. The location will vary between different vehicle manufacturers, models,
and production years.
Do not use this product on '06 or '07 Ford F-150 trucks. Faulty wiring in these vehicles
may cause a fire.
Warning: The MT 3000 is NOT a waterproof or sealed device. Care must be taken to
ensure the device is kept away from water or any other liquids.
Carefully insert the MT 3000 into the OBDII socket.
After the device is installed, ensure the device is working properly as evidenced by a GPS lock and cellular connection, which can be validated by the LEDs.
- 22 -
Figure: 18 - Typical OBDII Socket Location
Warning: Upon vehicle ignition on, immediately following device installation, the
device starts the Accelerometer Auto-calibration process.
5.3 Accelerometer Calibration
The accelerometer undergoes an automatic calibration sequence on the first drive after any of the
following events:
Device installation
Software upgrade
Vehicle battery replacement (or recharge if battery was fully discharged)
Device auxiliary processor reset

impact on events triggered by accelerometer readings.
Before installing the MT3000 make sure the vehicle is parked on level ground.
The vehicle should be driven in a straight path on level ground during the automatic calibration. An
inclined surface will put part of the gravity vector into the XY plane, which will affect the acceleration
thresholds. (A 5.7 degree angle will place 10 % of the gravity vector into the XY plane.)

6 Network Test Procedure
6.1 Configuration
The Enfora Mobile Tracker family of products is designed with features to support a robust connection with
the network. However, there can be conditions when the connection to the network or the ability to
transfer data across the network is beyond the control of the device alone.
6.2 Equipment Needed
In this example the requirements are:
GSM2374 MT 3000
Computer with one available Serial port or USB-to-serial converter
GSM/GPRS SIM with GPRS data enabled.
An APN (Access Point Name).
Username and Password, if GPRS is operating on a non-transparent network.
Note: If you don’t know the name of the APN you need to use, please contact your cellular
network carrier for that information. Once you have acquired this information, please
complete Application Note GSM0000AN019 – GSM Network Configuration Worksheet and
keep this worksheet for future reference.
6.3 Configure the Computer and Verify Correct
Communications
Please refer to Enfora document ENF0001IN001 – USB Installation Guide for detailed instructions for
installing USB drivers and connecting with the modem.

1. Connect and verify connectivity with the device.
a. Connect the PC connector to the device.
b. With HyperTerminal open, hit the Enter key. The device should respond with OK. If you do not
see this response, double-check your connections. If the connections seem correct, disconnect
the MT 3000 from the computer and perform a serial loop-back test.
c. Type AT. The device should respond with OK.
i. If you do not see the letters AT, send the following command to the device:
ii. ATE1
d. Type ATI. The device should respond with Enfora, Inc. If you get any different response,
you are not connected to the Enfora device. See Figure: 19 - "ATI Response"
Figure: 19 - ATI Response
2. Configure the device to communicate with the Enfora Test Server.
a. The following information will need to be obtained from the SIM provider. Please refer to
GSM0000AN019 – Network Configuration Worksheet.
- 25 -
i. APN
ii. Username and password (If necessary.)
b. Reset the device to factory defaults:
i. To restore the device to factory defaults, send the following command: AT&F
ii. To write current configuration to memory, send the following command: AT&W
iii. To reset the device, send the following command: AT$RESET
c. Configure the device to access the GPRS network.
i. To configure the device with the proper APN, send the following command:
AT+CGDCONT=1,”IP”,”apn” (substitute the letters “APN” for the supplied APN.)
ii. To configure the device with the proper username and password, (if necessary) send the
following command: AT%CGPCO=1,”username,password”,0 (substitute the correct
username and password)
iii. To configure the device to enable auto GPRS registration, send the following command:
AT$AREG=2
Note: When the device is reset, Windows will detect the detachment of the device
and you may have to close and reopen the communication program to reestablish
communications with the device.
Verify GSM status by sending the following command:
AT+CREG?
If everything is working, you should receive one of two responses:
+CREG: 0,1 (GSM registered to home network)
OR
+CREG: 0,5 (GSM registered roaming.)
Verify GPRS status by sending the following command: AT%CGREG?
If everything is working, you should receive one of two responses:
- 26 -
%CGREG: 0,1 (GPRS registered to home network)
Or
%CGREG: 0,5 (GPRS registered roaming.)
See Figure: 20 - "Verify GPRS Status"
Figure: 20 - Verify GPRS Status
Verify GPRS activation by sending the following command: AT$NETIP?
If the response is non-zero, then everything is working.
See Figure: 21 - "Verify GPRS Activation"
- 27 -
Figure: 21 - Verify GPRS Activation
If AT$NETIP returns all zeros, send the following command: AT$CGEER
There are three common responses:
$CGEER: no PDP reject cause (Everything should be working OK)
$CGEER: requested service option not subscribed (APN is incorrect or SIM has not been enabled for
data mode.)
$CGEER: user authentication failed (username and/or password is incorrect.)
Configure the device to access the Enfora Server.
To configure the device for server interoperability, several things have to be addressed:
Most GPRS configurations are Mobile Originate only. The mobile device must initiate a conversation
with a remote server before the remote server can talk to the device.
IP addresses are dynamically assigned and can change.
Some IP addresses are NAT and are non-routable IP addresses.
These issues are addressed with the following configuration commands.
The examples will use the following information:
- 28 -
l
Modem ID/name = “MT_Test”
Remote Server DNS address = apitest.enfora.com
Remote Server IP port = 1721
1. Give the device a unique name send the following command:
AT$MDMID=”MT_Test”
This command, combined with the wakeup message, will allow the server to associate a Public IP address
with a specific device and create a window of opportunity where the server can send commands to the
device See Figure: 4 - "Wakeup Command"
2. To talk with a specific server send the following command:
AT$FRIEND=1,1,”apitest.enfora.com”
3. To set the port number send the following command:
AT$UDPAPI=,1721
4. To Enable periodic messages (wakeup) to be sent to the server every 60 seconds send the following
command:
AT$WAKEUP=1,1
See Figure: 22 - "Wakeup Command"
- 29 -
Figure: 22 - Wakeup Command
6.4 Verifying Server Connectivity
Note: For the following tests, Java Runtime must be installed on the computer. (To install
Java Runtime, please visit the Java website: http://www.java.com/en/download/manual.jsp)
1. Start Internet Explorer and enter the following URL: http://apitest.enfora.com/udpapp/
2. Enter the name used in the MDMID command in the box. Select Connect See Figure: 23 - "Verify
Server Connectivity"
- 30 -
Figure: 23 - Verify Server Connectivity
3. Select the tab with the device name. (In this diagram it is labeled "MT_Test") Within approximately
60 seconds the wakeup messages should be seen in the window See Figure: 24 - "Wakeup Messages"
- 31 -
Figure: 24 - Wakeup Messages
4. Enter the following command in the command/ data block:
ATI
5. Select Write
6. Verify that you see the device respond with Enfora, Inc. See Figure: 25 - "ATI Response" . If so,
you have successfully configured the device to talk with the server.

Figure: 25 - ATI Response
6.5 Verify GPS Operation
Follow these directions to verify GPS Operation.
1. From the terminal window, send the following command: AT$GPSRD=10
2. The device should respond with a standard GPRMC message that looks similar to the following:
$GPRMC,221223.00,A,3301.5080,N,09642.3857,W,000.0,000.0,230805,05.9,E,A*19
A = OK
V = Warning
9 = Enfora Specific response that GPS solution is not valid and the last known GPS location is being
substituted.
