    Fwiw..I had a c5 z06 and had a column lock issue as you described. I found that replacing the battery solved my problem.

    The C5 and C6 are very sensitive to voltage dips and that could set off DIC messages such as this or service active handling.

    I always recommend starting off with the simplist solutions.

    Good.kuck deciding what to do.

    HI there,

    Also, please confirm that the recall was done at GM.

    The feedback relay that is installed at the recall can create inaccurate signals.

    If your battery has more than 12.5 volts and the battery terminals are clean and torqued to 11 ft lbs, I would inspect for that relay and REMOVE IT COMPLETELY!

    Column lock bypass can create internal BCM failures so I DO NOT recommend that course of action.

    Allthebest, Paul
