I have been sorting through the problems bit by bit. Today I reinstalled the ABS module that I have been working on. I opened it up with a razor knife and found that a capacitor had become dislodged. After obtaining some solder. solder wick, and soldering tips from the owner of a local electronics shop, and watching a youtube tutorial on soldering, I successfully reattached the capacitor to the board and sealed up the unit with epoxy meant for bumper repair. Although the ABS light is still on, my speedometer and odometer now work again! I am going to examine and clean the individual wheel sensors next to see if I can get the ABS light to go out.
