GM Tech2 clone C5 Corvette feedback

Many users have been confirming GM Tech2 clone is worth to pick for a C5 Corvette. Let’s read what does GM Tech2 clone can do for a C5 Corvette.

Feedback 1:

I bought the Tech 2 (clone, works great) for my C5 (99) just for the Automated Bleed so I could completely flush the brake system particularly for the EBCM !!! Have since used the crap out of it, ECM/PCM re-learn, crank sensor re-learn etc !!!!

Also use it to exercise my ABS motor every 3 months.

Feedback 2:

C5 has the built in ability to pull vehicle specific DTC’s right in the DIC and those can be exceptionally helful in diagnosing and correcting common C5 issues.

There are a number of functions in addition to diagnostic trouble shooting that can be accomplished with the Tech II.

and another is the ability to program out unwanted features such as F45 or F55 RPO’s ar program RPO’s into a replacement BCM.

Do recognize that the tool have extremely limited ability to change settings in either the PCM or BCM. To accomplish change you need a programming tool such as HP Tuners or EFI Live and they can change only PCM settings.

they’re very easy to use,just follow the display,and look around till you get tired,,and try reading ”live data” as much as you can,it speeds up the learning curve,,and try it on as many GM cars/trucks as you can too

Tech 2 installation Question and Issue:

Question:

when I try to connect it to my car, I get

this message:

no communications with vehicle

check diagnostic link connector

check ignition <off/on>

I have my key in the on position but not running, cable connection appears to be correct.

Possible reasons:

Possible Reason 1:

Are you feeding a separate 12volt to the Tech 2 or are you only using the OBD2 cable ?

I feed the 12volt from the sigaretteholder into the end of the OBD cable .

The 120VAC input 12VDC output power supply that is supplied with the Tech2 should only be used when working offline. It can mess with the ground reference if it is powering the TECH2 while connecting to the vehicle.

When connecting to the vehicle the Tech2 can be powered from the DLC (OBDII connector), cigarette lighter power cable or the battery clip power cable.

Possible Reason 2:

If your battery gets a little low then the Tech2 will start having problems.

The Tech2 itself can be a bit of a drain. If your key is on then you have day time running lights and accessories being powered as well.

It is better to have a battery charger connected and start with a full charge.

Try the self check with the Tech2 not connected to the car’s OBD2 port using the AC adapter.

Possible reason 3: Do not have it set up correctly

go on youtube and watch a couple how-to videos.

Possible reason 4:

The parts has defect.

Suggestion: I’d be looking for parts to repair it before sending it back. I got mine for $200 shipped and wouldn’t like to know how much it would cost to ship it back from the US but assume it would be at least half of what I paid.

BTW, you can buy from obd2eshop.com shop (item NO. SP23-1) which are reliable.
