AEM 33-0034 Wideband OBDII not showing on VCM

[Poppacapp]

Hi,

Wonder if anyone else has had the issue I am having.

2017 C7 Grand Sport. Have been using my AEM wideband with pass thru OBDII setup for past week.. has been working fine. Over the past few days it has randomly not worked with VCM Scanner. It will show unconnected on my PID list, and when I start a scan, it disappears with no data.

The gauge is working fine, and lambda shows on the gauge like it should. Just not getting to the laptop software.

Could the pass thru cable be going bad? I am using the factory default setting from the gauge/controller.

Thanks for any advice you may have.

Thanks for the link. I checked this morning and it was working again. If it stops again, Ill try the method in the vid.

My gauge is very sensitive to the wires being inserted properly and completely into the back of the gauge.

I haven't had an issue again so far. I will keep the wiring in mind if it happens again. Thanks!
