Foxwell NT204 User manual

QUICK START GUIDE
This Foxwell Code Reader is designed for analysing engine issues on OBDII compatible vehicles, including both
petrol & diesel. Suitable for both DIY / professional use, this code reader will read / clear OBDII codes and turn off
the check engine light. It also displays a range of live data / freeze frame data on a 2.4" TFT colour screen, along
with hot keys for an I/M readiness test. This code reader comes with lifetime free updates.
Please note that this code reader will only work on OBDII compliant vehicles. You will need to refer to your vehicle
manual, or use this QR code to reference our list of Australian OBDII compliant vehicles. For pre OBDII vehicles,
you will require a scan tool such as the ET2530.
