@oldskoolgarage Any update or fix on this error code? I am still running with it on but am long past due state inspection. I do not want to put the shutters back on and am looking for some other solution. Thanks!

Yes we fix it but on the 2025 unfortunately you have to put three of the shutters back in the grill.
