Software description:
The OBD-II software used by Bluetooth ELM327 is free software. After you connect the computer with the on-board computer hardware in the car, you can obtain the information you need from the on-board computer.
The software interface is friendly and beneficial to the user.
Software features:
Software can do the following:
Read error diagnosis codes, generic and manufacturer specific, and display their meaning (database has more than 3000 of the general code definition)
Clear the error code and turn off the MIL (check engine indicator)
Display current sensor data, including:
Engine speed per minute (RPM)
Calculated load value
Coolant temperature
Fuel system status
Speed
Short term fuel conditions
Long term fuel conditions
manifold pressure
Injection advance time
Intake temperature
Air velocity
Absolute position of throttle valve
Oxygen detection voltage associated with short term fuel state
Fuel system status
Fuel pressure
There are many other data on fuel consumption monitoring, and so on
Note: Bluetooth adapters can detect general faults in power systems, chassis systems, communication systems, and body systems. According to the standard fault codes that are open to each model, about 3000~6000 of the common fault codes can be monitored.
