OBD interface position is generally in the steering wheel at the
bottom of the interior trim board, near the driver's knees, a
slight difference between different models of position, but the
basic location are similar.
OBD interface with trapezoidal form of 16 needle DLC connector,
trapezoidal interface is false proof design, if device interface in
the wrong direction cannot be inserted, in case of errors caused by
insert short circuit or other conditions affect vehicle use.
When 4G GPS tracker connect with can bus OBDii connector, it will
automatic read the data from the vehicle, and upload those data to
GPS tracking platform to generate one OBD report.
Explanation of Nouns
Accumulated Mileage(km): After installed OBDII, car ran across the mileage
Instantaneous Fuel(L/H): Car one moment of fuel consumption
Average Fuel (L): When the car on the road every hundred kilometers average fuel
consumption
Running time(S): From car engine on to car engine off, car ran across time.
Speed (km/h): Car speed
Live Load: At constant engine speed, its performance index, along with the
change of load in must keep the speed constant when the load
characteristic is measured.
Temperature(℃): Coolant Temperature
Throttle Open: The engine throttle opening Angle. By the driver through
accelerating car engine throttle pedal to manipulate, to change the
volume of the engine, to control the operation of the engine.
Different throttle opening marks a different engine operating
condition.
Engine Speed:High and low engine speed, work is related to the unit
time the number of how many or the size of the engine's effective
power, namely the effective power of the engine with engine speed
and change
Voltage: The car battery voltage
Error Code: Read diagnostic trouble codes, both generic and
manufacturer-specific, and display their meaning (over 3000 generic
code definitions in the database).
