Take example : 2001 Chevy PCM programming with GM TECH2 + TIS2000

In 2001 the Chevy service manual says the PCM can only be reprogrammed making use of the Pass Through approach.

The pass by means of programming system calls for the use of a scan tool in series with all the Techline terminal along with the DLC.

The original 10 MB version from the Tech 2 from obd2tool didn’t offer you Service Programming System (SPS) as an alternative. It appears like the Tech two was only a pass by means of device between the car and the Techline Terminal inside the early days (1997). SPS may be the solution that enables remote programming so without having it the pass by means of strategy would happen to be the only method available. That is the most likely purpose my 2001 manual says pass by means of has to be utilised. I am confident the newer Tech 2’s will plan the Tracker PCM using the remote technique.
