A couple days ago, the ABS and TRAC OFF lights came on about a minute after leaving home, and stayed on till I turned the van off several minutes later. Came back after a few hours, and the lights were on when I started it, then turned off right when I started pulling out of the parking spot. And today, my wife says they came on repeatedly during her hour drive to work. We haven't noticed any weird ABS activations or anything like that. I know a scan for ABS codes will tell me most of what I need to know, but do these symptoms point to anything specific that I can check out in the meantime?

 

Bump. It's been on constantly for the last several days.

 

I bought an OTC 9450 scanner that says it'll do 01-08 T&C ABS codes. But it does not. Not out of the box anyway... I am trying to download the Scanner Suite program off their website, but the 321 mb program is downloading at 24kb/s. Maybe it will update the tool, not holding my breath. Tried their tech support line. No help.

Anyone know of a tool that will actually retrieve ABS codes for me?

 

I got another scanner and it worked. It's a loss of signal from the left rear speed sensor.
