New Car wireless OBD2 OBDII ODB2 EIm327 BlueTooth V1.3
ELM327 (Bluetooth) is the latest PC-based (PC) scan tools. It supports all OBD-II protocols and is compatible with many software. It is the output agreement to USB port and computer (notebook computer) interconnect.
Light-emitting diode (LED) indicator:
OBD I / O (Tx / Rx), RS232 input / output (Tx / Rx), Power Supply
12 V, built-in circuit to prevent short-circuit and overvoltage protection
ELM327 USB use OBD-II software is free software, computer and automotive in-vehicle computer hardware connected, use the software, you can get from a car computer the information you need.
Friendly software interface, which will help get started. Installation is simple - to extract the files to a computer hard drive folder, which can begin to use; to delete the folder as a whole can uninstall the software.
Software supports two platforms: DOS and Windows
The software can do the following:
Read error diagnosis codes - General and manufacturers special use, and display their meaning (the database has more than 3000 generic code definitions)
Clear the error code and eliminate off MIL ( "Check Engine" light)
Display current sensor data, including:
The engine speed per minute (RPM)
Calculated the value of the load
And short-term fuel the state associated with the oxygen probe voltage
There are many other data ... ...
The future of software features:
Continuous and discontinuous oxygen probe results
Jaguar MINI Mercedes-Benz Volkswagen BMW
Suzuki, Honda, Toyota, Mazda, Mitsubishi
Infiniti Land Rover Skoda Chevrolet Hyundai Kia
Aodisabo Opel Peugeot Citroen Fiat, Volvo, etc.
With the continuous development of vehicle technology, automation technology in the new electric car manufacturing and maintenance process is used, the new
Yang is no longer a simple mechanical operation, but increasingly rely on electronic, computer-based professional tools. Over the past, vehicle maintenance is
Mechanical repair and spare parts repair the main, and modern vehicle maintenance is driven electro-mechanical systems in order to diagnose the core diagnostic techniques.
In response to the new trend, the depot of vehicle electronic control system design, while also greatly increased the degree of fault break from the clinic
Function of system design. Self-diagnosis system can run in the car during the continuous monitoring of electronic control system, including: engine starting
Move, the engine running, water temperature, driving speed, electronic ignition, fuel, intake air, load and other system operation status. Once the hair
Anomalies of the situation, and then set the specific algorithm according to parse out the cause of the malfunction, and these fault codes are stored in the road system, ECU
The memory at the same time starting to run fault corresponding module functions and the implementation of security measures (such as the fault indicator / Fault warning
A / V automatic cut-off corresponding to function), to remind the failure to go to a car repair shop for maintenance; and technical maintenance personnel can use the steam
Car diagnostic equipment to read the fault code, accurate fault diagnosis and rule out the problem.
(B) vehicle-control agreements and diagnostic equipment
Current national depot vehicle control protocol used in the following categories:
Other types of vehicles digital / analog control signals and protocols dedicated
Most of Taiwan's new car to use ISO agreement, the old European vehicles using KWP Agreement, part of the co-BENZ cars using the MOST
Will compare the new / advanced Japanese / European vehicles are also used to the CAN BUS Agreement (VAG for AUDI / VW B6, MAZDA 6
, Etc.), while the next generation of stars the agreement is FlexRay. CAN BUS agreement also commonly used to automate industrial control systems
(Eg, temperature control / air conditioning controls elevator, etc.). Usually below the steering wheel and pedal board there would be a margin between the diagnosis J1962 16PIN
Broken socket (as shown in Figure 3) so that you can OBD2 connection cable (as shown in Figure 2), to connect the plug 16 PIN J1962
At present car computer diagnostic equipment can be divided into two kinds of types:
1. General Purpose Diagnostic Equipment
Can only be read / clear error codes, error codes will PXXX string displayed on LCD, the error code read out after going to turn the manual to be
Connect your computer to use, graphical-based display interfaces.
The agreements for the majority of vehicles the engine ECU to monitor, dynamic data analysis and recording, read / clear error code.
Including the VIN CODE reading, engine speed, vehicle speed, engine temperature, load, Air flow rate, O2 sensor, TPS
Applicable to many types of vehicles.
2. Proprietary diagnostic equipment type
In addition to engine, will also include the ABS / instrumentation / Transmission / Airbag / comfort CODEING / SELF TEST / LOGIN.
Original use, strong function, are factory proprietary software and hardware price is not cheap.
These agreements are mostly in the physical layer / data link layer of the Protocol, the agreement required with the upper (eg, SAE1979) to carry out
After the sequence analysis of the information presented.
This product is OBD2 general-purpose computer diagnostic equipment, support OBDII-ISO 9141-2 / ISO 14230-4
(KWP2000) / J1850 VPW/J1850 PWN / CAN ISO-15765-4 agreement, the use of public version of ELM327 V1 decoder IC set
Meter, ELM327 help us deal with the underlying (Layer1/Layer2) and the upper (application layer) of the communication, so that the program developers do not have
Ignore the complex communication between the Agreement, as long as compliance find AT commands can be quickly applied to software development.
Commonly used to detect the engine data including engine speed, vehicle speed, engine temperature, load, Air flow rate, O2
sensor, battery voltage, vehicle number, vehicle computer and information, and may clear the error code.
Using the method to ScanMaster 1.1.0 version as an example:
1. OBD2 program will be open, and OBD2 connector into cars.
2. Connect COM Port before the test make sure the port number, and in ScanMaster program [option] / [Communication] is located
COM Port set to set to connect port number, Protocol is set to automatically detect, BaudRate part of the requested set.
3. The above steps set up, please do not start the key to open prosperous, the connectivity test. Please click connect.
4. Test is successful you can see the connection chip elm327 v1 / agreement / auto voltage information.

? The types of vehicles tested system with reference to foreign test data, but different countries in different regions of the same types of vehicles may be due to regional depots
Strategies with different results to differ.
You need to use ISO refers to ISO ELM323 decoder. ELM323 supports ISO 9141-2/KPW2000 agreements vehicles.
CAN means the need to use CAN ELM327 decoder. ELM327 supports CAN / ISO 9141-2/KWP2000/J1850 agreements vehicles.
