Vag kkl 409.1 software crashing serial#
an USB KKL adapter (it provides a virtual COM port, for example ‘ AutoDia K409 Profi USB‘ – it uses the FTDI chipset to emulate a serial line).Set basic settings – useful, if you want to start motor ECU throttle adaption.Note: my software only supports the older KW1281 protocol!įeatures of my KW1281 diagnostic software: Finally, I decided to develop something on my own. So, using the KW1281 protocol, the correct initialization timing (baud 5) is critical, and some software does not wait before waking up the ECU. CarPort 1.3.2: seem to work (you have to power off/on ignition while connecting as it sends some data before waking up and that confuses my engine ECU).VAG-COM 3.11/4.09: seem to work (you have to power off/on ignition while connecting as it sends some data before waking up and that confuses my engine ECU).monoscan 2.30: seem to work, but does not have ‘set basic settings’ feature.wbh-diag 0.89 : seem to work (unstable connection).My Audi A4/B5 (1997) and many other old cars use the older OBD KW 1281 protocol – I tried to find any suitable OBD software for my car to speak to my motor and dashboard control units ( ECU), however: Arduino code was written for the KW1281 protocol to read car sensor data (RPM, oil/coolant temperature, throttle, air, etc.) and show them on the display.ĭownload Arduino Code for the KW1281 OBD protocol: arduino_kw1281.An Arduino LCD display (‘YwRobot LCMI602 IIC V1’) was attached to the Arduino.An OBD USB adapter (USB KKL adapter ‘ AutoDia K409 Profi USB‘) was hacked, so I could connect the car OBD to the Arduino (TX/RX via software serial).Update 2015: I developed an Arduino OBD reader for the older OBD KW1281 protocol:
