Where is the RELAY located for the turn signals?

scottdk · Feb 15, 2009

I have looked in the manual and in the fuse panels, but can't seem to find the relay for the turn signals.

Any ideas??

OK, I give up. Why do you need to know where the turn signal relays are located on a brand new car under warranty?

I will be adding LED amber turn signal bulbs, and in order for the car not to have problems with bulbs that don't create much electrical load, load equalizers need to be installed or better yet the turn signal relay gets replaced with a relay designed to work with regular bulbs or LED, preventing any fast flashing or no flashing at all problems.

I've been looking for it (for the same reason) without success too.

Closest I've come was somewhere where it said it was under the dash somewhere on the driver side but I haven't had a chance to go look for it there yet.

Click here, then open the document and scroll down to page 18. This will help you isolate the right part, but probably won't help find it. To do that, you will need to invest some time at http://www.hmaservice.com . In the shop manual, I would start with the Body Electrical System. I believe the part location is buried in there somewhere.

I went through the service manual cover-to-cover and nowhere do they actually say where the relay is, or even if there is one.

Are you referring to the manual that came with the car, or the online shop manual?

The service manual mechanics use to service the car.

Scott, which 'relay' are you planning on changing?

Turn Signal Lamp Control
The Turn Signal Lamp Control function controls turn signal lamps and indicators.

1.FAM : Normal Operating Condition
While IGN Switch FAM is IGN state, if Turn Signal RH Switch or Turn Signal LH Switch or Hazard switch is ON then turn signal outputs are turned ON following the switch input (LEFT, RIGHT or HAZARD).

2.FAM : Double Blinking Condition
In case of activation of hazard the fault detection will be able to detect the failure only if 3 bulbs are broken-down.
The double blinking works at IGN Switch FAM is IGN state, double blinking for Hazard.
In case of turn signal activation when one of the FRONT or REAR is broken-down (Lamp failure), the turn signal blinks with double frequency.

3.FAM : SCG (SHORT CIRCUIT TO GND) Fault Condition
If The FAM detects Short circuit to Ground, then FAM turns off the OUTPUT
.The fault detection is carried out continuously, until fault is confirmed by FAM. Once FAM confirms SCG, FAM keeps the fault condition until flasher trigger condition is changed.

BaywayRic, that's the description of the blinker logic within the on-board computer (FAM), which is all the service manual says about the blinker and leads me to believe there may not be a relay at all on the Genesis.

That would really suck because that would mean we would have to install resistors across the blinker wires to "fake" real load in order for LED blinker bulbs not to trigger the "Fault Condition" ie make the on-board computer think the bulbs are burnt. That would also prevent the computer from being able to detect when an LED bulb is burnt.

BaywayRic · Feb 15, 2009

Agreed. I thought the closest thing to a "blinker unit" would be the part marked CLU. Re-looking at that, it seems to go to the indicators on the dash, not the bulbs, which leaves the FAM.

I am going to call the dealer to see if they might know if there is a relay and if so, where it is located.

It wouldn't surprise me if they didn't even know, since the car is still pretty new.

Thanks for all the replys everyone

OK, I have called multiple Hyundai dealers and no one knows where the relay is for the turn signals.

One gentleman thinks that it may be located in the trunk, so I ripped that apart and didn't find any relay for the turn signals there either.

I guess time will tell with this issue.......................................

When you put on the flasher, you can here the realy click or is that a speaker turning out a relay sound?

Just a ting to look into

CIAO

You can he the subtle clicking, but it is not the flasher.

I've installed LED's in other cars and the relay has been located under the hood, which in turn isn't the relay making the clicking sound since I wouldn't be able to hear it from there, and I do not know what actually makes that sound.

bbk · Feb 24, 2009

Not sure if this helps, but the FAM is located under the hood, grouped alongside 10 relays. (See HMA online manual/ETM/Component Location. There you'll find a series of 141 photographs. FAM is depicted in PHOTO.140)

To scottdk: I can tell you for sure that load equalizers will be required for LED replacement of the rear turn signal lamps. It's not a problem; when you pull the plastic socket and OEM bulb out of its housing, you'll find a couple of inches of lead wire to which you can attach the equalizers. The fronts, however, are going to be a problem. Not only do the front signal bulbs have the funky, dual-contact, BA15d base (more common on combination tail/turn and sidemarker/turn signals), but the plastic bulb socket, itself, is not attached to wires. The entire socket and bulb come completely off the vehicle. The socket has two contacts, molded into the base, which connect when the socket is properly positioned in its housing. Therefore, no place to attach load equalizers. Since successfully locating the turn signal relay seems to be less and less likely, I've pretty much resigned myself to go with incandescent stealth bulbs in front.

At this point I'm just holding off doing any LED for the turn signals due to the issue you mentioned. A relay would be much better and easier than the annoying Load Equalizers and I'm sure in time I will find out where the relay is. When I do, it will be a super fast and easy solution that is im my opinion worth waiting for.

bbk · Mar 6, 2009

I fully agree; a much easier install if the relay can be located. I am, though, having trouble locating an amber LED with the BA15d base. I've tried all the usual suspects (Autolumination, Diode Dynamics, V-LEDs, SuperBrightLEDs, etc.), but have been unable so far. Have you found a merchant who has them?

Gimli · Mar 6, 2009

Are you sure it's a BA15d base and not a BAY15d base? "Normal" 1157 and 2357 both use the same BAY15d base.

Are the two pins level with each other or is one higher than the other? Here are diagrams of both socket specs:
