iOBD2 Diagnostic Functions:
Read DTC: Read the current DTC that engine has stored, and DTC
Clear DTC: Clear all the current DTC.
Display DTC Definition: Show all the definition and explanation of
Guide Maintenance:Guide how to maintenance the problems of car
according to the trouble codes.
Live data: Read all the running parameters that related to the ECU.
Freeze frame data: OBD system will record the system running
parameters related to the malfunction the moment when it occurred
at the same time when it set the DTC. And this group of data is
called freeze frame data.
Readiness test: Readiness reflects the status that all the valid
diagnostic functions. The diagnostic functions are referring to the
important monitoring functions in OBD system, e.g. Oxygen sensor
monitoring, Oxygen sensor heater monitoring, and EGR system
monitoring, etc. These diagnostic functions are closely related to
the engine emission control.
Read vehicle info: Read vehicle info such as Vehicle Identification
Number(VIN), Calibration IDs(CALID) and Calibration Verification
Oxygen Sensor test: This service is to allow access to the on-board
oxygen sensor monitoring test results. The same information may be
obtained by the use of [Mode 6 test].
Mode 6 test: This service is to allow access to the results for
on-board diagnostic monitoring tests of specific components/systems
that are not continuously monitored. Examples are catalyst
monitoring and the evaporative system monitoring.
EVAP System Test: The purpose of this service is to enable the
external test equipment to control the operation of an on-board
system, test or component.
Idle Mode: Engine rotational speed, water temperature, battery
voltage, Air-intake temperature, Instant fuel consumption
(static),average fuel consumption, Ever wished you had your own
customizable gauges, showing only the data you were interested in
Cruise Mode: Vehicle speed, the current engine load, water
temperature, vehicle travel time, vehicle travel average speed,
Continuous running mileage, instant fuel consumption(dynamic), ever
wished you had your own customizable gauges, showing only the data
you were interested in.
Sport Mode: Show you the engine rotational speed, vehicle speed,
Performance Mode: Show you the vehicle speed, capacity, torque,
horsepower and you can also customize your gauges here.
Driving Track (Racetrack Mapping)
It is to show the driving track of the vehicle to give data and
foundation for reference. Open the Location Services of the mobile,
connect iobd2 to the vehicle and open iobd2 APP, choose "My
Dashboard", and it will record the track of the vehicle. Quit "My
Dashboard" then it will stop recording the track of the vehicle.
The Performance Test Function Includes:
Accelerate/Decelerate Test: Test acceleration/ deceleration process
time and distance.
0 to 400m Acceleration Test: test spend time from 0 to 400 meters.
It allows users to change the unit of temperature, mileage, vehicle
speed, fuel, fuel consumption, torque and horsepower, set the alarm
for over speed, fatigue driving and water temperature, and set
parameters of vehicle weight, fuel consumption coefficient and
vehicle speed coefficient according to their needs on [Customize My
It is to save and review the recorded diagnostic data of the tested
cars, such as live data, freeze frame data, trip record and my
dashboard data. The data can be shared to Facebook and Twitter .
If you meet any problem when testing your car,please give us a
feedback according to the below steps, an engineer will reply you

Does My Car Have OBD-II?
All cars and light trucks built and sold in the United States after
January 1, 1996 were required to be OBD II equipped. In general,
this means all 1996 model year cars and light trucks are compliant,
even if built in late 1995.
Two factors will show if your vehicle is definitely OBDII equipped:
1) There will be an OBD II connector located under or around the
2) There will be a note on a sticker or nameplate under the hood:
"OBD II compliant".
Where is the connector located?
The connector must be located within three feet of the driver and
must not require any tools to be revealed. Look under the dash and
The Three Flavors of OBD II
While the parameters, or readings, required by OBD II regulations
are uniform, the auto manufacturers had some latitude in the
communications protocol they used to transmit those readings to
scanners. Naturally, each felt they had the one true way, so we
have three different OBD II communications protocols in use.
What Communications Protocol does my vehicle use?
As a rule of thumb, GM cars and light trucks use SAE J1850 VPW
(Variable Pulse Width Modulation). Chrysler products and all
European and most Asian imports use ISO 9141 circuitry. Fords use
SAE J1850 PWM (Pulse Width Modulation) communication patterns.
There are some variations among captive imports such as the
Cadillac Catera, a German Opel derivative, which uses the European
ISO 9141 protocol.
On 1996 and later vehicles, you can tell which protocol is used by
examining the OBD II connector:
J1850 VPW--The connector should have metallic contacts in pins 2,
4, 5, and 16, but not 10.
ISO 9141-2--The connector should have metallic contacts in pins 4,
5, 7, 15, and 16.
J1850 PWM--The connector should have metallic contacts in pins 2,
4, 5, 10, and 16.
