  • You Reply: Got it working with LiquidCrystal using Arduino 1.0.5. I used the wrong I2C cable with wrong capacitance.  Ended up using Cat5e. It is also worth noting that this is the proper library for this particular LCD:

  • You Reply: Thanks for the reply! Last night, I verified that the LCD was working with both the Nano that came with the kit and the Uno r3. So, I think the length of the harness is most likely the issue here as I have completely disconnected the UART OBD-II and still cannot scan or send data to the I2C.  While testing, the length of the cables used was 6" vs 3' (harness).  I will most likely need to use/test cat5e for connecting the I2C.

    This helped me understand better:
