My Trac off light has intermittently been goin off and on while I am driving. When it is on, I am not able to turn it no matter how many times I hit the button. I have checked all the wheel speed sensors, especially the rear pass one( I just had that hub replaced).
From reading other post, I saw others mention the ebtcm and that it could be cleaned. I unfortunately have no idea where it is.

I would really like to know where it is and how I would go about cleaning it if this is possible.

Thanks

The EBTCM is the Electronics Brake and Traction Control Module. It located on the drivers front in the engine bay, below the PCM. You'll need to remove the air filter housing to get to it.

I actually have a FWI, so the PCM is exposed. Maybe i'm missing something but I dont recall anything being below the PCM.

Check your brake and signal lights. My 01 Montanna had Trac light come on. The cause was an open in brake light circuit Due to rear light module terminal connector burnt.
Both vehichles may utilize some of same DTC'*
Can you get to it from removing left front wheel house extension.
I don't think cleaning unit will correct DTC. You will want to check related harness connectors and wiring for intermittent faults.
