hi, I can't login normally so I am going to answer this as a guest.

it's possible that the communication to the dash is compromised. Does your scanner only show engine codes or does it allow for communications with different modules? If you can use the scanner and look at the dash module see if there is communication between the modules. Or check for comm. codes
