Today I have a test on 2005 GMC to show you how to read and clear diagnostic trouble codes from the ABS system via GM Tech 2. You should use with a 32MB Card which can support your car model before staring.

Here we go!

How to Clear ABS Codes using the GM Tech 2 scanner Video:

Connect GM Tech2 diagnostic tool to vehicle including OBD and DC power first.

Switch ignition on and turn on GM Tech2 scanner.

Main Menu is displayed on the screen and then select F0: Diagnostics

Select vehicle Model Year, 2005 is mine.

Select Vehicle Type, I need select LD truck

Select Product Make. I select GMC Truck

Select Product Line

Select Product Series

Select Chassis in Diagnostics menu to star reading.

Select Traction Control Option

Let’s continue

Select the ABS

Select DTC in ABS menu

Select DTC Information

Select Current Diagnostic Trouble Code

The Diagnostic Trouble Codes will be displayed on screen, NO Diagnostic Trouble Codes will be displayed if the vehicle has no problems.

Return and select Clear DTC Information if you can see codes there.

Select Yes to continue

The DTC’s, Freeze Frame, and Failure Records are being cleared.

Codes have been cleared, so you can select DTC Information again to see if any other problems in your vehicle

And you will see No Diagnostic Trouble Codes if problems have been figured out.

My test has done, as you see the Tech2 for GM is so handy and capable that takes me less than 4 minutes.

There is only 3 ways that the VAS 6154 or TC XS will work as Porsche Piwis 3

1. you flash the GL123…… from VAS to pt3 (you will get also the Serial from the Donar)

2. You use some home made firmware (serial from VAS will stay there also you can see on the webserver that the emergency firmware is still VAS or TC XS)

3 you use the same way like the VCX do it. after the Piwis system will think it is a PT3G.
the VCX do the same

You buy a original or any decent china clone PT3G remove there the GL128, read the data out buy some new GL128 progamme it with the data and solder the ic back to the vas interface and you are done.

But you have to know the risked, we damage the pt3g and have to repair the board, we have to manufacture a plastice to fix the bold GL128 back on place right place you have only 1 chance.

for me as a solution to much work.

I paid some people to make some firmware but until now no 100% working firmware.

The last solution is the easy.
You just buy a xvc after the xvci is working on your system you change all know xvci data to vas 6154. and you are done.

You have to do it after every update.

last version is

you just pay some porsche sparepartmanager some money and order there your pt3g.

but than you will not get the interface for 1400€
