Had the ABS light and traction control light come on and I wasn't getting regen when I braked anymore (which is a weird feeling). So of course I pulled over and tried restarting but the same thing happened about 10 seconds after I took off. After about a 20 minute drive with no change (my Torque is running this whole time) I realize that Torque hasn't been updating for a while. So I pull over and see if there is an error code but it said it wasn't connected. So I pulled the OBD and restarted again. I took off and no dummy lights and regen was working. Could only drive for a few minutes but all seemed well. Thoughts?
I experienced this once as well, its definitely related to your obd link./ torque. The thread linked below addresses your problem: Abs lights are turning on but only when I use Torque | PriusChat
I have had this happen on my Prius v and wife's PiP when I had the cheap ($20 - $30 on Amazon) Bluetooth obd dongle plugged in. It was solved by pulling over and unplugging the dongle and a restart of the vehicle. Changed to Garmin obd dongle and I have not had the problem since.
I had the same experience it was the sender for my Torque the plug in device failed, tryed it over and over many times, finally ordered a different type,problem went away!
After using new OBD for a couple of months, it now failing again at an increasing rate. I unplug it for a couple of days try it again and it works for a day then fails again with same alarm lights lit and same lose of regen and ABS. I use torque with my old Samsung S3.
