sys flashing
Just charged batt after a long winter and started Yvette.....beside speedo where the fuel milage indicator is a sys pops up then goes back to the fuel milage...is the ecm just rebooting because of the batt disconnect? Or is there something wrong?

I wouldn't worry about it short term, drive it for awhile and see if it goes off...9 times out of 10 it means the battery is weak, but after driving and letting the alternator top of the battery it might clear itself.

Could be an internal short in the battery as well. Make sure its fully charged. If you see Sys again pull it an have it load tested. If it fails time for a new battery.
