Possible to let dealer turn off hyperflash check on BCM

Is it possible to ask dealer to turn off bulb check from car's central computer? I heard the hyper flash check is now controller by Body Control Module instead of old school turn signal relay.

Did anyone ever contact dealer for this inquery?

Then we don't need to add a load resistor to get rid off hyper flash.

Re: Possible to let dealer turn off hyperflash check on BCM

Unfortunately that is not one of the programmable options in the BCM or RFH modules, no way for the dealer to turn it off.
