My ABS, TC, and check engine lights are on. Plus speedo doesn't work and power steering goes in and out. btw, the problem goes away at a wim and comes back. Very strange.

Codes are 500 (speed sensor), 2108 (lost communication with ABS Module), and 1700 (TC module). How could this all happen at the very same time? There must be a single root cause.

My car is a 2000 Catera with 80,000 miles, btw.

Thank you!

I believe the ABS unit goes bad after some time and It needs rebuilding. Dig around here and you will find a few posts on the issue. Then you can find the site that offers the rebuild modules and simply get one.

I believe the rebuild process actually makes it work even better then the OEM Unit.
