Emissions test unable to connect/communicate (blackbear tune issue?)


Recommended Posts

Hope I’m under the the right category. Took my truck in for inspection and emissions and I guess they couldn’t get it to connect/communicate to do the emissions? could this be because of my blackbear tune being loaded?

Blackbear has their own page on here in the supported by section. I’d post this question there or call/email them directly.

Also go to your local parts store and try using their code reader (if you don’t have access to one) to see if it communicates with the truck to confirm it wasn’t just the testers equipment. Then try your auto cal and see if it communicates.

Yeah I e-emailed them. Doesn’t appear they think the tune conflicts with that. I have my aeroforce gauges hooked up and they connect just fine.

I agree.  Blackbear shouldn't interfere.  Something is preventing the onboard OBDII terminal form making a connection to the testing center's equipment.  bummer.

I’m willing to bet the idiots disconnected one of my gauges and connected to the Y and not directly into the OBDII port.
