No communication with obd2 scanner

Most likely what I'll do when we get warm weather again. Would that cause a check engine?

yes and/or you would maybe get a "check gas cap" warning just depends on how much of a vacuum leak there is, if the solenoid failed to complete a cycle it would throw a cel.

So I checked the fuse for the cig lighter and it was OK, but I'm still getting the communication error. What would I try out next?

Just wish I wasn't getting a communication error. I ordered a different code reader incase that one just doesn't work with it.

you can ohm test the obd port pins to check to be sure it has communication and rule the code reader in or out, google obd port test and it will give the specs for a couple pins that are critical for comm's

Will do this weekend. We just got snow so I'll wait a couple days

From what i've read, the evap emission system will cause check engine, and if you have a check engine light on, remote start will not work.

anything that makes the check engine light come on will prevent a autostart but that is irrelevant here.

Yeah, that's the problem. My obd2 port wasn't reading my thing. I bought a fixd one and it worked fine. Guess it's a known problem for these vehicles
