Interesting email/report from Onstar Services

[rav3]

Today I received an email from Onstar Services with a monthly report on my truck. I get these just about every month although I stopped my Onstar service after my 3 months of free service. The report was interesting as they reported per below. All other information was correct for mileage, oil life, tire pressures, etc. And yes, I do have a Ranger AFM deactivator plugged into the OBD2 socket. I never realized that this device would keep them from accessing some of the trucks systems. Just thought I'd share.

I had one in my 2017 since new and never got anything like that. Every month I got the report as usual.

Yes there have been other reports of range doing this. You don't need to worry.

 

 

My amp steps are plugged into the obd and onstar reads everything fine fwiw

My 18 Tahoe had the same problem. I think 18+ it shares the same port the range is using in which onstar can’t communicate
