The OBDCheck VP39 is a cost-efficient entry-level OBD II diagnostic scan tool that can be used to diagnose the check engine light (or Service Engine Soon). It’s easy to use – plug into your vehicle’s 16-pin OBDII DLC, turn the ignition on and connect. You will be able to get the trouble codes along with their definitions on the screen. It also provides other useful features that are available on expensive scan tools.


Check Engine Light Diagnostics

With the OBDCheck VP39 you can easily read the codes causing the check engine light to come on. You can check what’s wrong with your vehicle, potentially saving yourself a trip and cost to the mechanic for minor issues. You can then reset the light.



The scan tool does not read ABS, airbag, TPMS, or maintenance required lights. Erasing the trouble code does not mean the fault have been solved. You should repair your vehicle as soon as possible.

  • Supports multiple trouble code requests: generic codes, pending codes and manufacturer specific codes

User Manual


The device works with OBD II compliant vehicles (year 96 or newer in the US). It does NOT work with OBD I vehicles. For OBD II compliant vehicles, there should be a 16 pin DLC (Diagnostic Link Connector) usually under the dash or behind ashtray AND a note on a sticker or nameplate under the hood: “OBD II compliant/certified”.

It reads check engine light trouble codes (sometimes called service engine soon).

Check the cigar fuse of your vehicle and try on another vehicle to see if the OBD connector is in good condition.

Make sure your vehicle is OBD2 compliant, the device is plugged in well and the ignition is at ON. Also start the vehicle to try again. Try it on another vehicle to see if the device is defective or incompatible with your vehicle.

First check if you have any other dash lights on. Sometimes fault from other systems will also cause the check engine light on. Or it’s a manufacturer-specific code that is not in the code library of the device.

Please note that not all codes can be cleared in this way. For some codes (especially confirmed or permanent), if the problem causing the code hasn’t been fixed, it won’t be cleared or it may be cleared, but will come back again right away. We usually suggest that you first use the code to check your car and fix the problems.

The user manual only covers generic DTCs from P0001 to P0999. For codes that are not covered or if you need more information about a code, you may Google it or use websites like https://www.obd-codes.com, www.autocodes.com which provide more information like definitions, symptoms, possible causes and troubleshooting steps.
