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 Tech2. You should use with a 32MB Card which can support your car model before staring.
Here we go!
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
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.
