2020 Chevy Silverado Windshield camera calibration

Griff Technician Oregon Posted   Latest  

Attempting to do a windshield camera dynamic calibration on a 2020 Chevy Silverado 3500 Duramax. I am using GDS2. KOEO, parking brake is on, no codes. When I command it to go into calibration mode it says the module has rejected the command. I have done several of these with no problems. Any suggestions on a resolution would be great. GM glass is installed.

I guess my first question would be why was the windshield replaced? I have had this happen a couple of times. First off on the cluster is there a message stating the camera is not available or something to this affect and is the LDW in Yellow? If so, I would go into the data pids. There should be pids stating it is in calibration mode. If so, drive the vehicle until it states it is no longer in…

Agree with Robert. Also make sure the camera is too the latest software before attempting the cal. Also why is the cal being performed?

Long shot, Try running command with engine on. Or in drive. Maybe module is expecting a parameter that GDS is not prompting.

likely a hardware /software change and poor Chinese to American translation. Look closely at the direction for changes. Some want you to start vehicle then press ok, some want the opposite . Gotta interpreter a lot but they a lot of changes I an NOT a fan of!
