I am looking to buy or rent an older GMC OBD2 bidirectional scanner.
Prefer GM Tech 2 for GM trucks up to 2007
I have a 2005 GM Yukon 4WD.
I need to clear the TCCM Transfer Case Control Module after replacing the Transfer case and control motor.
It does not shift into 4WD High.
NOTE:
The TCCM, along with many other body and chassis modules, communicates via the Class 2 serial data bus (SAE J1850 VPW protocol). ISO 9141-2) is available, GM Class 2 communication (SAE J1850 VPW) was used on most GM vehicles from the mid-1990s through ~2007.
