Product Description
The All New Advanced Car OBD2 Scanner Code Reader
The Exctool ET331R is the all-new upgrade from basic OBD II code readers in all aspects. Not only can this full OBD2 mode OBD2 diagnostic tool read diagnostic fault codes and freeze frame data, it can also retrieve live engine parameters, O2 sensor test/ on-board monitor test results and do an EVAP test to better help you diagnose car issues. It‘s plug and play: plug into your vehicle’s 16-pin OBDII DLC and you are ready to go. It has a huge DTC library and will be a very useful and reliable auto accessory which offers comprehensive vehicle information for rapid, accurate diagnosis and repair.
Live Data
Retrieve real-time data or status from various sensors and components in the vehicle, such as engine RPM, coolant temperature, vehicle speed, oxygen sensor readings, and more.
Mode 05
Provides access to the engine control module oxygen sensor monitor test results. Not available on vehicles with Controller Area Network (CAN) system. Go to Mode 6 for these cars.
Mode 06
On-board monitor tests: It allows access to the test results for on-board diagnostic monitoring tests of specific components that are both continuously monitored (e.g. misfire monitoring) and non-continuously monitored (e.g. catalyst system).
EVAP Test (Mode 08)
It allows you to Initiate a leak test for the vehicle’s EVAP (Evaporative Emission Control System) to check the integrity and functionality of the system that captures and stores fuel vapors.
Make Car Diagnostics Easy
Save Time & Money
Perform a quick diagnosis of your car anywhere when you have a check engine light on the dashboard. It enables you to read the fault codes, find out what the problem could be and perhaps fix it yourself, or give you a peace of mind in case you need to see a mechanic.
Fast & Reliable
Thanks to built-in high performance MCU and increased DTC database, you can get accurate diagnostic results in seconds.
Review & Print
You can print out the diagnostic data (DTCs & Sensor Data) for your record or send to your mechanic for help.

Common Q&A
1. What vehicles is it compatible?
Cars and Light trucks made since: USA – 1996, Canada – 1998, European Union & UK – 2001 (gas), 2004 (diesel), Australia – 2006 (gas), 2007 (diesel), Mexico – 2006, etc. (OBD II, EOBD or JOBD Compliant )
2. Does it work with electric or plug-in hybrid vehicles?
No.
3. Does it read error codes in non-OBDII systems like ABS, airbag or tpms?
No, it only read check engine light or MIL codes (emission-related).
4. Can it reset oil light, or perform other service reset functions?
No.
5. What live data can be read by this diagnostic tool?
Readable parameters depend on what’s installed on the OBDII system by the manufacturer. It usually includes engine coolant temperature, long & short term fuel trim, mass air flow rate, fuel rail pressure, oxygen sensors, etc.
6. Why does code erasing fail?
Some codes require the fault to be fixed first, or some special procedures are required. It’s up to the car maker.
