This is driving me nuts. 3 years with this car on a lease, not a problem... BUT now that I'm 3 days away from turning it in, everything seems to be going haywire!

Now I have the car on my floor jack as I had the sleeves and oilpan/gaskets replaced. All seems well. But when I put the keys in the ignition, now the ABS fault warning is showing on the dash!

(2005 STR by the way)

Could this be caused by having the car jacked up all day? It's been on the jack since early this morning. Never had a problem before now? Of course the car has been sitting for nearly 2 weeks, but again, prior to jacking it up, now fault warning...

 

Flattish (or may even be failing) battery?

Maybe had the ignition on and turned a wheel..... more likely the battery, though. Don't have it tested by AutoZone (etc) as it'll likely be "good" even if bad.

If it's a "fake" error, it'll probably clear when driven (above 15mph or so).
