I have not had the ABS checked out by anyone. With the mileage at 187,000 and with both ABS and traction control (on the DIC) being on, I figured I would just replace the ABS wiring (harness) as I have had the ABS/TC light come on before on the other GP's I owned.
In my other high mileage GP (274,000 miles) I just pulled the bulb for the ABS and covered the traction control light with black tape. Been like that for 7 years.
But, you raise good point that there could be more going on.
I need to get some money together and buy a fully functional scan tool to that I can check things out on my own. It is pretty much against my religion to take any one of my GP's to a shop. All the shops around me don't seem to have a clue how to diagnose anything.
I had no idea that Rockauto sold a harness for ABS, I will send for one of those.
Thanks for the advice everyone!
