^ not sure what that review is talking about. my reader didn't come with a CD just the module.

Like i said, it's worked fine for me for many years but YMMV

 

I'm kind of a code-reader novice. I have a basic OBDII reader and have grabbed some codes off various vehicles so I get the general idea. What I'm wondering is the procedure with shopping for and checking a C5/C6 Corvette. Would a reader be redundant with checking the codes from the DIC by pushing the dash buttons? Can anyone recommend the best comprehensive reader for these Vettes (if different than what's listed upthread)? I don't mind spending a couple hundred dollars (or more?) if that's what it takes. I just really want to be able to check out that aspect of my purchase ahead of time.

 

In my opinion checking out codes are only one aspect of troubleshooting cars. To be able to view sensor signals are also importent to verify diifferent sensors .
In addition to have bidirectional to is very nice . If I window does not go up , you can use the scan tool (like Tech2) to force doormodule to drive the windows up and then troubleshoot/measure the relays /wires .
You can also verify if the doorbutton for window up works does operate corret by viewing input signals on the scanner .
Having a bi-directional scanner is very time efficient during troubleshooting comepared to only using a codereader .

In my own experience if you you don't have a laptop a Tech2scanner is a good way to go if you have a C5 /C6 .

If you have a laptop win10/win11 a VCX NANO with the Tech2win program and a 9 feet USB cable is a good way to go .
You have to download some software and instal it but youtube show you how .

I prefer Tech2win menu on a 13/15" laptopscreen over the small (8"?) screen of the Tech2scanner

I have a SnapOnUltra Edge and Autel MK908P scanner in addition but I mostly use Tech2win with the VCX NANO when I service/troubleshoot C5's .

Just recently I bought the TOPDON Topscan USB dongle using blooth to my Iphone . It has can be used against a lot of car brands , has bi directional capabilities ,view live data and create a detalied scanreport for the car
like this :

 

Just looked into this and ordered from Amazon. I've been wanting a Tech2 or so but I'm just a recreational guy so my TorquePro app and cheap OBDII reader has been good until now. My wifes 2015 Yukon gives some suspension errors due to the Mag ride shocks being removed and resistors on so I always have to take to my buddy with his Snap on scanner to see what's going on. Sounds like I can figure it out on my own now. Thanks.

 

Got my TopDon in and love it. Can read lots of modules, see sensors/live data and activate stuff to troubleshoot. Had some reward points on Amazon so got it for free and I'm sure it will do anything and everything I'll ever need. Thanks again for the tip.

 

I'm glad you liked it and it seems to be very nice low priced OBD2 Bluetooth dongle with good quality .
I you use the attached usb cable to a phone charger you can power it inside your and connect to your your phone using the buetooth and download manufature (brand) software the dongle by means of home wireless network instead of the mobile nettwork
If you see my last screendump and press ME (lower right corner) you can access Diagnostic reports and Data stream reports(recorded live data) on your phone

 

I have been looking to get me a scan tool, but wanted more than just a code reader. I want to be able to stream data and chart it, and since some diagnostic procedures require bi-directional functioning, I want that also, and I want to be able to use it on my 2017 Tundra as well.
(I know I'm not asking for much...) I found a Foxwell NT530 that seems to foot the bill for $223 with software for both GM and Toyota. (It's $159 without the Toyota software)

Foxwell NT530 OE-Level & Bi-Directional Scanner Upgraded Version Of NT510 Elite & NT520 Pro
It looks similar to the Foxwell NT301 that MSG C5 bought. My question is, do you think that I am buying more tool than I will likely ever need? I have been having fuel sending unit issues and intermittent P0442 evap system codes as well. The NT301 has code reading/clearing and data streaming capabilities, but not the bi-directional functioning. It only costs $63, but I don't know if it will work on the Tundra.

 

NOTE OF IMPORTANCE: I have learned to change the #7 plug and/or wire from BENEATH the car

I use the OTOFIX D1 Lite. I think they run about $350. So far it does all the same functions as my old Tech2 clone did.
