When i had it checked no reading can been found is there a fuse that will not allow the code from being seen if blown?
I think the shop cant read the code if it has gone by the time you get to the shop.
Its probably within the steering column like the ignition wires. Happened to me. Quick and easy fix. I found out after buying 2 new fuse boxes
