99 concorde still not running
 

Well, here is the latest update to my Concorde driveway ornament...I've been checking the sensors, and i have 5 volts to the sensors. Checked the door switches they have 11.46 volts to them. Here is the part that I don't understand. Untill recently, the only code that came up was 1684. I swapped out the asd (which still opens up) relay with the fan circuit relay and a new code showed up.(fan relay) then i unplugeed the TPI (that code showed up), but when i unplugged the cps no code. So does this mean I've got bigger issues or is this part of the vtss? Please any sugestion would be helpful...
