Need stock flash tuned put on ECU...for some reason my ECU is not telling my cooling fans to turn on..had shop run diagnostic and that is what they came up with....any help would be appreciated....thanks

 

Have you have the computer out (unplugged)? If so, the connections may cause your issue; reseat the connectors and push to seat them all the way down.

Also verify that your computer is seeing the correct temp reading from the temp sensor (not the same sensor as the dash gauge).

 

checked the relay?
