Hyundai Repair: Daytime Running Lights, adobe svg viewer, hyundai santa fe


Question
I have a 2007 Hyundai Santa Fe.  I would like to be able to use daytime running lights whenever the ignition is on like they have for cars in Canada and GM cars.

I now use the parking lights in the daytime but I prefer using daytime running lights because then your rear lights are not on like they are with the parking lights.  I feel this makes it harder to distinguish the brake lights in the daytime.

I notice there is a drl light fuse opening in the inner fuse panel.  I installed a fuse but that did not solve my problem.  I assume I have to add something besides the fuse to make the daytime running lights work.  What do I need?

Would greatly appreciate any help you can give me.

Answer
The Santa Fe is sold in many markets (countries), but not all markets have all features.  DRL is not available in the U.S.  Most likely, the fuse box is the same, but you don't have the control module or additional wiring present for DRL.  

You'll need to do significant modifications to get the front parking lamps to illuminate without illuminating the rear tail lamps.  These lamps are all on one circuit.

The headlamps, however, are separate.  You could set something up to turn them on separately from the tail lamps.  I encourage you to register for a free account at www.hmaservice.com so you can look at and see the schematics for your vehicle.  It'll hopefully help you understand what I'm going to suggest.  The site requires Internet Explorer, and you'll probably need Adobe SVG Viewer (free download) to see the schematics.

The headlamps are signalled to be turned on by grounding the blue/black wire that runs from the headlamp switch to the BCM.  You could achieve your goal by installing a relay that grounds this circuit whenever the ignition is on.  To do this:
1.  Wire one side of the relay coil to the red wire in pin three of the ignition switch connector.  This will provide power to the relay coil only when the ignition switch is in the "on" position.
2.  Wire one side of the relay contacts to the blue/black wire (pin 15 of switch connector) mentioned above.
3.  Wire the remaining coil terminal and the remaining contact terminal to ground.
