Is there anything that could cause the test to not even initiate? My bushing is crud, on top of that I am thinking the speed sensor or TPS, if not both, are done because I have to rev up to 4-5K to shift into 2nd. My hub is blown due to me being a noob so I can't check if cruise control will engage. I thought I might try the self test while the car is immobile, but there is no light besides when it does turn on for the few seconds once the ign is in the "on" position.
