DTC:                                                  Diagnostic trouble code
For “Cumulative mileage, remaining fuel, average fuel consumption”, tracker will identify intelligently and display it if vehicle protocol supports, otherwise, no “ODO, FLI” in the message.
If it supports “cumulative mileage”, then you can set the travelled mileage; if it supports “remaining fuel”, then you can set fuel tank volume.

The “average fuel” means the average fuel consumption of 100km; it will be showed only after driving 10km at least.

2. Set mileage: Send SMS “ODO+password+space+100000”, mileage units is kilometre, tracker will reply “Set ODO ok!” after succeed. Device will automatically add this travelled mileage in the value of cumulative mileage.

3. Set Fuel tank volume: Send SMS “tank+password+space+60”, fuel tank volume in litres(L), Tracker replies “Set tank ok! “after succeed . The default fuel tank volume is 60 litres.

4. Notification of Vehicle fault: When a vehicle malfunction, the vehicle malfunction indicator light is on, diagnostic trouble code will be automatically sent to the authorization number.

If in GPRS mode, Device will report to server centre every time when vehicle starts, and only one notification in SMS mode.
5. Vehicle maintenance notification: Send SMS “service123456 365d 10000”, tracker replies “service ok!” after succeed, when the travelled mileage over 10,000 kilometres, or when the device accumulated 350 days of work, it will send maintenance notice to the authorized numbers15 days in advance. If in GPRS mode, Device will report to server centre every time when vehicle starts, and only one notification in SMS mode.
6. Single Locating :
* If there has any authorized numbers been set up, tracker will reply to all calls with location report. If the authorized numbers been set up, then only authorized numbers will be able to receive location report from the tracker;
* Dialing the tracker device from the authorized numbers, it will hang up the call and respond a message with google map link and real-time latitude and longitude ;
* When lost fix to satellites (no GPS signals), it will track by LBS / CELL-ID. Then the replied SMS will include two positions:
– GPS coordinates of the last known position.
– LAC code.  Open www.gpstrackerxy.com find “manual track”, and put the received code in LAC and Cell-ID fields to location by LBS technology.
7. Auto track continuously:
* Track with limited times upon time interval, for example send SMS command “fix030s005n +password” to the tracker device, it will report the position information with 30s interval 5 times.
* Track with unlimited times upon time interval, for example send SMS “fix030s030m***n+password” to the tracker. Tracker will report a real-time location every 30 seconds when ACC is ON, and report location every 30 minutes when ACC is OFF. Note: The interval must not less than 10s.
* Smart track upon time and distance interval, this function means that the device can be tracked by preset distance and time interval two factors.

The GPS data stop updating if vehicle is not driving (ACC is OFF) and latitude and longitude always keep the same, and GPS data updates automatically when vehicle is moving (ACC is ON).
10. Location based service (LBS) / Cell-ID Locating:If the tracker cannot establish a solid GPS Fix, it will calculate its location using Cell-ID GSM locating. Location reports will include the GPS coordinates of the last known positions as well as a LAC code, Entering the  LAC code to the “Manual Track” menu of web tracking platform www.gpstrackerxy.com will enable you to see the tracker’s current location. You can also send command “address+password” to the tracker to request exact address, track will automatically switch to tracking by LBS in GPRS mode.

*It depends on the capacity of the SD card inserted in the tracker device.
* The logged data in SD card can be copied to computers, and then the data route can be checked by importing data in the menu “Data Import” of web platform www.gpstrackerxy.com

14.Data Load:

Unit: Meter).  It will reply “move OK”. In case of such a movement (the default distance is 200m), it will send SMS “Move+ latitude & longitude” to the authorized numbers.

* Overspeed Alarm:for example, if you want to set the alarm speed as 80km/h, then when the target moves exceeding 80km/h, the unit will send SMS “speed+080!+ latitude & longitude” to the authorized numbers. it will send only one SMS in 3 minutes in SMS mode when overspeed, the siren will beep 1 time when overspeed 1 time.

17.Set up arm/disarm by SMS
* Arm/lock:send SMS command “arm+password” to the tracker, the terminal of vehicles will change to arm state, Meanwhile, car door is locked, and it will reply SMS “Tracker is activated”. If the vehicle are in ignition state (ACC is ON), car door will be locked, but ARM will fail, Meanwhile, it will reply SMS “set up fail! pls turn off ACC”. If engine is off, but door is open, then the car can’t enter ARM state and reply “setup fail, pls close the door.”
* Disarm/Unlock:send SMS command “disarm+password” to the tracker device in the vehicle, It will reply “Tracker is deactivated” in both armed and disarmed state, and the SMS command will make the tracker device enter into disarmed state if the unit currently armed. It won’t alarm if the door is open and sensor is vibrated and the engine is started when deactivated this arm function.
18. Alarms under Arm State:
* ACC Alarm:the unit will send SMS “ACC alarm+lat/long” to the authorized number in at interval of 3 minutes when the engine of the car is turned on, that is the key is rotated to “ACC ON” position to start the car in arm state; Siren will be sound for 20 seconds, and repeat again at interval of 20 seconds if  the ACC always keep ON.  Disarm to stop this alarm.
* Built in Acceleration Sensor Alarm:The tracker is built in three axis acceleration sensor, the tracker can detect it in arm state when the vehicle move, tilt or shock. The alarm way is same as the external shock sensor alarm.

19. Sleep Mode:when vehicle is not driving (ACC is OFF), GSM module fall asleep; GPS module shut off; and tracker works in low power consumption. Calling, SMS command and any triggered alarm can wake up it.It can sleep by time, sleep by shock and can start work at specific time.

20. Forward the third parties’ message:for example, set the phone number of the service provider of the SIM card in the tracker, when charge remind message coming in, tracker will forward it to authorized phone number. Only 1 third parties phone number can be set up at most.
21. SIM card Balance Inquiry:How it works: take China Mobile as example, After accept balance command, tracker will remember the “mobile phone number”, carrier’s phone number and the code, then send the code to carrier’s phone number, and forward the message from carrier to mobile phone number.
22. Check the Vehicle State:send SMS command “check+password” to the tracker in the vehicle, It will reply SMS including:external power、battery、GPS signal、ACC、Door、GSM signal、GPRS status、APN、UP、IP、PORT etc.
23. Terminal (local) Time Setting:for example: Send SMS “time zone123456 8”, 8 is Chinese time zone, If your country time zone is minus, send SMS “time zone123456 -8”.
24. Reset Hardware:send SMS “reset+password” to tracker device to reset the GSM module and GPS module of the tracker device, it will reply “reset ok”.
25. Less GPRS traffic:tracker will change to less GPRS traffic mode after parking 5 minutes (ACC is OFF), GPRS disconnect and connect again when alarm being triggered or vehicle starts driving.
