Stereo asks for code,
no turn on or will on then powers off?
This problem was troubleshot to poor connections on the
ceramic fuses in the fuse box under the hood. Access the fuses, twist each
fuse in it's holder. This will clean the contacts at both ends of the fuse
and may bring the stereo back to a more reliable working condition.
