GMC Yukon Daytime Running Lights
I just bought a used 2005 Yukon Denali XL in Florida and have brought it back into Canada. The vehicle has daytime running lights - which is a requirement in Canada, however the master light switch has the ability to turn off the DTRL's... and this is a no-no in Canada.
Does anyone know if the onboard computer can be re-programmed to disable the ability to turn off the DTRL's?
Alternatively, is there a wire than can be disconnected from the master lighting switch on the dashboard so that the ability to turn off the DTRL's can be taken away? Does anyone have a wiring diagram, or details on the back side of the master light switch?

1. The DTRL circuit is operated by the Light Switch; however, managed/controlled by the BCM, so have you checked with you local dealership if they can program the BCM to have the DTRL always ON?
2. Have you checked with your local GMC dealership parts department to see if the light switch that they have in Canada is different from the US version (having the option/position to turn OFF the DTRL)? Can't believe it can be that simple though... I think programming the BCM has a better chance.
Good Luck!
