No test driving it now with hazards on voltage is 14VDC. BUT I did have to jump it for sitting long about a month & 2weeks before this happen.
Expert:  Lou P. master tech replied 4 months ago.

ok, after the battery is discharged or disconnected you need to rotate the steering wheel from lock to lock to learn the steering angle sensor.

it needs adjusted when it is installed or it will trigger warning lights.

I pulled out the lever, then installed it, & stepped on the brake with normal pressure 3 times, & test drove it.
Expert:  Lou P. master tech replied 4 months ago.

ok yeah thats it, but we hold down the brake pedal when installing it that way the plunger doesnt make contact until the pedal is released but sounds good enough what you did.

did this problem come out of nowhere ?
