From what I'm seeing in the other threads they are integrated. Which makes sense. EX:

"From the 2000-2001 Electrical Troubleshooting Manual
The T.O.D. control unit receives an input from the ABS system, when active, to apply voltage to the clutch solenoid (transfer)."

Took the Vcross to a recommended shop, Mr. Transmission, but they couldn't access the TOD codes after all. They checked everything else and it was good. no codes from any other systems including ABS. Good people. No charge. I'll definitely use them if I ever need transmission work etc.
So it's down to just whatever the TOD problem is. At least it drives fine.
