Start up after battery unhooked since Janurary

[stateroadhog]

So Battery was unhooked on my 2015 SS 1LE since January just now got car started up after installing headers. Car has not moved since then. I unhooked several wires including the ground that bolts to right head and moved it to diffrent location also the electric power steering wires to reroute to clear headers. So upon starting I have an ABS light, both traction control lights are lit and its says the steering needs service and stabilty control not functioning and cel light is on. So I plugged my code reader in and no codes. So I'm wondering if these will go away if I drive car and it starts reading sensors or I have another problem? Any help would be greatly appreciated.

how old is the battery? if the battery is good, clear the codes, drive a bit and see if they come back on.

reset the codes...if they don't pop back, you are fine....i have had similar issues out of storage.

With a code reader you wont be able to communicate with the ebcm or pscm

Where did you move the ground?

Once you drive the car, all that ABS and TCS should go away, that's what
happens when you disconnect the battery. You have to drive the car to
turn all that off. Just working on mine, and pulling the battery, I get those
flags, then have to drive it, they all turn off.

With an electric rack, you should only need to start the car, turn the wheel
all the way right, then all the way left, then center to re-calibrate it.
The lights may go out after that. Else, yeah, you have to drive it.

If the CEL is on, you should get a code from a reader. The CEL is only
required to illuminate on emissions control device issues. Being that the
car sat that long, ALL the oil drained out of the top end, to the bottom.
That means, the VVT Solenoids were empty, and all your hydraulic
motivated parts. Just needed time for oil pressure to build up in all
those devices to time the car.

If you know someone who has a tuner, connect it to your car just to
read and clear any codes. "U" codes won't show up on a basic scanner.

I moved it to the body where the main ground from motor connects to body. then I moved it back to original position no change.

Thanks for all the info guys really apprieciate it. will let you know if driving

[stateroadhog]

Also have two different tuners and they both show no codes

thanks again for the help

OK so I drove the car about 8 miles the ABS light is still on along with both traction control lights. The CEL turned off. Still says to service steering and stability control. did I not drive it far enough or do I actual have another problem?

did you happen to take the steering wheel off at any point?

[stateroadhog]

No I didn't. I did unhook the wires to the steering to re route them. Checked the wires everything is plugged in all pins look good. The steering feels like it is working.

just thought if you removed the wheel, you could have put the clockspring out of center....then it may think you are overturning the limit and throw the stabilitrak.....maybe the steering angle sensor?

[stateroadhog]

So the right front wheel speed sensor had come unplugged under the ABS pump bracket. What a pain to get to. I don't think it was ever plugged in all the way as they snap in pretty tight. Thanks to everyone for all the imput which helped narrow it down
