X Series OBDII wideband AFR error code

Good Morning:

 

I purchased and had installed an AEM  wideband AFR gauge yesterday and it will only show the code l1.10. Nothing else will display. The installer confirmed that the gauge is installed correctly. I can’t find any information about this error code and need to figure this out so I can finish tuning my vehicle. Any help would be appreciated.

Again, the code showing is l1.10 and it is on a 2017 Camaro ZL1.

 

Thank you.

Try loosening the three

Try loosening the three screws on the back of the gauge a 1/4 turn, sounds like both buttons are stuck. Having both buttons pressed while powering up the gauge will show the FW version. You could also try wiggling the two buttons to see if they are indeed stuck in the pressed position and see if they work their way free.
