The tires are the same size and pressure on all four wheels. I don't think the system locks up at high speeds, I can't feel it. The ASD system is only supposed to work up to 16 MPH anyways. The wheel speed sensors may be corroded from sitting.

The biggest problem I have now is that when I do the diagnostic test I can't get any blinks out of the ASD light. Supposedly I need to put a jumper wire from number 1 to number 5, or just number 5 to any ground and count the number of times the ASD light blinks. Even if there are no problems it is supposed to blink once. It never blinks at all.

Thanks
