7. Vianmääritys ja usein kysytyt kysymykset

Q1: What is the version of the ELM327?

A1: This is the real V1.5 High Quality version, featuring the original Microchip PIC18F25K80. It operates at a frequency of 4MHz (crystal oscillator) and supports ATAL and ATPPS commands, as well as all OBD2 vehicles.

Q2: What is the difference between V1.5 and V2.1? How can I check it?

A2: Our ELM327 is 100% V1.5, which supports a full set of 10 protocols, including J1850 & J1939 Protocols crucial for Japanese and American cars. Other ELM327 versions (often V2.1) may only support 7 or 9 protocols. You can often check the version within your diagnostic application (e.g., ELM327 Identifier app).

Q3: Does this adapter support diesel cars or trucks? Is it working with iOS?

A3: Yes, the ELM327 protocol generally supports diesel vehicles. This specific KW902 model features Bluetooth-Compatible 5.0 and is designed to work with both Android and iOS devices. Ensure your diagnostic application is compatible with Bluetooth 5.0 Low Energy (BLE) for optimal performance with iOS.

Q4: What functions can I perform with the ELM327?

A4: The device allows you to read, erase, and display diagnostic trouble codes (both standard and manufacturer-specific), measure fuel consumption, display real-time operating performance (e.g., engine RPM, vehicle speed, temperatures, pressures), turn off the "Check Engine" light, download data, and record various parameters for real-time graphical display.

Q5: What is the function of the ON/OFF button?

A5: The blue ON/OFF button is used to reset or wake up the device. This new design incorporates an auto-sleep mode, which activates after 30 minutes of no communication. The sleep mode consumes very little power (only 10mA), so you don't need to worry about draining your car battery if you leave it plugged in overnight.
