Might be a dumb question but is there a way to disable the daytime running lights on a 07 ram1500?
Need a scan tool, as suggested Alfa OBD. If you know anyone with a StarScan that'll do it too. Are you sure they're DRL's and not the headlights set to auto? Mopars in the US generally don't have DRL's activated (it's a requirement in Canadia).
From the FSM:
• Daytime Running Lamps - Vehicles manufactured for sale in Canada illuminate the high beam filament of the
headlamp bulb in each front lamp unit to serve as the Daytime Running Lamps (DRL).
DAYTIME RUNNING LAMPS
Vehicles manufactured for sale in Canada illuminate the high beam filament of both headlamp bulbs at a reduced
intensity when the engine is running, the parking brake is released and the exterior lamps are turned OFF. The
TIPM must be programmed appropriately for this feature to be enabled. Once enabled, anytime the TIPM receives
.electronic messages over the CAN data bus from the PCM indicating the engine is running and from the EMIC
indicating the status of the headlamp switch exterior lighting input is OFF and that the parking brake is released, the
TIPM provides a pulse width modulated voltage output to the proper headlamp bulb filaments through the right and
left high beam feed circuits to produce illumination at a reduced intensity.
