On my 2003 Z06 I had the recall done in Frbruary, They removed the locking plate and installed the K harness. Yesterday when I started the car I got the pull key and wait 10 seconds message so I did . Now all it does is give the service colum lick message. I bought a lock bypass kit today and installed it but it didn't change anything. Do I need to have the K harness removed to use the bypass kit?
I'm not sure how the "harness K" connnects if it doesn't plug into the connector the CLB plugs into?
If you have the CLB in place, disconnect the battery for a few minutes, then reconnect it. This should reset the BCM and clear the column lock message. If your CLB is correctly installed, you should be good-to-go.
