Customer Reviews
Good, Fast, Easy![]()
I am a professional Technician. This little handy dandy tool is fast, easy, and gets to the point of the problem with little to no issues.
Self powered, and can tell you current codes, pending codes, as well as what monitors have been run. Comes with a nice booklet that explains how OBDII works, and has a code chart for most cars.
Well made, Ive had mine for a few years now, its far easier to use then most “top dollar” scan tools.
Cannot show sensor values in real time.

Comprehensive and convenient OBD2 code reader![]()
This code reader is easy to use and provides comprehensive drive train diagnostic capability. Keep the instruction book handy, there is a lot of information on the display. This model will not read ABS/air bag faults (Equus does not make a reader for the ABS system).
It works!![]()
Bought this, spent 15 minutes studying the manual, plugged it in, and it worked first time — read out the “check engine” code, and, when later plugged into a PC, allowed the details to be printed in a nice report.
The only negative I’ve noticed is that when you reset the “check engine” code in the car’s computer, it erases the reader’s memory of it, so you have to do the PC printout before resetting the code.
Some folks believe that if you use a device like this on one car it’s “locked in” to that car and can’t be used on a different car. This is not true — I’ve used it on several different cars with no problems.
