Problem:
I needed to program and update my pcm on my 2018 Cruze before it grenades itself. Got the VXDIAG VCX NANO GM J2534 scanner, when signing up ACDelcoTDS website it says “Access unauthorized with destination system error. This is more than likely caused by the use of a counterfeit MDI or MDI2”
From their website
“Access Unauthorized with Destination System Error. ONLY if you get an Access Unauthorized with Destination System error – This is more than likely caused by the use of a counterfeit MDI or MDI 2. Aftermarket J2534 devices are not impacted.
WARNING- USE OF COUNTERFEIT “CLONE” GM MDI DEVICES will result in your account being locked. Aftermarket J2534 devices are not impacted. ”
Any solution?
Solution:
Vxdiag vcx nano/vcx se/vcx fd as a j2534 device is fine but using it as an MDI will get you banned.
Remove the driver for “GM GDS2/T2W” and “SGM RDS” and just leave Passthru driver. Don’t install GDS2/T2W crack software with Passthru driver on the same PC and you should not be banned.
After that log in ACDelco website then download Techline Connect.
Then follow this guide to set up SPS with vxdiag.
