I have no idea what happened. I got in and cranked up only to see the trip counter / odometer displaying "- - -". I then noticed that the speedometer read 45 mph and the tach showed about 1.5k rpms.
I turned her off and removed the key, both needs stayed locked where they were. I pulled the battery cables and that reset them. Upon turning her back on the odometer still remembered everything.
Everything seems to be working fine while driving.
What on Earth, any ideas? This really has me concerned
Now that I'm a little less panicked, some additional information...
2000 SR5 4x4, no codes during the issue and no codes now/after.
Update, it happened again and this time I snapped a photo. This was taken with the engine off and key removed. Once again, no codes or anything.
