2016 Colorado Remote Start

[BrianC.]

I just purchased my second Chevy Colorado and I am running into an issue.  The remote start won't work.  The doors lock, when I hold down the remote start button the lights flash but nothing else.

 

No engine light.

Hood is closed tight.

Not in valet mode

batteries good.

 

 

I took it to the dealer today and after 3 hours of waiting they said it was probably the main computer.  Granted this is with them saying they haven't even looked at it yet.  This service department has its own issues.

 

They are wanting to have me bring it back later for diagnostics and maybe 5-7 days if it needs a new CPU.

 

Is their any thoughts on how this could be a simple thing I can look at before wasting more of my time with the service department?
