Question:
Anyone having issues with these? So far the last 2 I try don’t want to work. 2020, no problem. 2021 no go. Tried with Jpad and Smelecom. What tool to correct mileage on GMC Yukon 2020/2021?
Answer:
These tools will do.
1. OBDSTAR Odomaster
Have done with obdstar odomaster successfully thou it took 3 times to take.
run hours idle hours miles km.
You will need CAN FD adapter to access.
Menu path: Cluster Calibrate->GM latest software version->GMC->Yukon ->2017 onwards-> Type 1 or Type 2 (try by yourself)->Mileage calibration
If failed, try several times or send log data to OBDSTAR engineer.
x300 dp plus does this as well. x300dp plus will also program keys (add key and all keys lost) for Yukon 2021.

2. Semelecom
One of our customers did a 2021 GMC Sierra with smelecom and it went through fine. Had to do it twice and also ran it as a Yukon or Yukon XL. All doors must be shut. Cruise Control did not work after job. Wasn’t able to solve that issue. Clear codes, battery off etc. etc.
Do brake pedal calibration relearn. This will resolve that issue.
3. JPROG7
Some used JPROG7 mini and worked with no issues.
