I installed the factory fog light kit and they only come on with the high beams. I double checked all the connections and they are correct. I saw something about a mod to allow them to come on all the time but can't find anything on that. Does anyone know how to fix this problem or how to allow them to come on anytime (at least when the parking lights are on)

Thanks

2002 Honda Accord V6 Sedan

 

Anybody know? If not I will have to pay the stealership to figure it out.

 

technically, if these are real OEM fogs...

and they "hooked up" into an existing harness...

they should only come on with the low beams

and shut off with the high beams..

 

That's why i don't know where the problem is. The honda schematics that come with the kit aren't that specific in showing which line gives power to the switch to allow them to turn on. It has to be a wiring problem either with the kit or the car. I think if I can change the wiring at the switch to draw it's power from an accessory line or something it should work whenever, I didn't know if anyone had any actual schematics.

 

OK, replacing the relay under the dash fixed the high beam problem. Now the green light on the fog light switch lights up when the low beams are on but the fog lights don't light up. The relay under the hood gets 12V from the battery, and the switch voltage (from the under dash relay) is 10.8 volts. Does the relay need 12V to activate? Maybe I have a voltage drop somewhere. I haven't checked the voltage at the bulbs yet, I didn't feel like ripping apart the front bumper again.

 

Okay i don't know what exactly you installed... or how its wired...

If you have the Genuine Honda Accessory Fog Lights, they are wired differently from Aftermarket OEM Reproductions....

You can wire the fog lights the aftermarket way...
check this thread: https://honda-tech.com/zerothread/1812043

most aftermarket fog lights are wired the same way....

all you need to figure out is the pin outs on the interior switch, and were to tap into the light on/interior lights/parking light lead, and a constant +12v source.

------

because you have said that ever since you installed the foglights, your highbeams and other issues have come up...

how about you explain how you connected everything up... either draw up a diagram in paint or use paint.net, inkscape, etc...

then upload the file to photobucket, or tinypic

and then use [i m g]http://hxxp://website.com/image[/i m g] to attach the image into the thread. (no spaces between i m g)

 

They are OEM, here is the link to the instructions:

The relay under the dash was causing them to come on with the high beams instead of the low beams. I installed a new harness (the one that goes under the dash) and the green light on the fog light switch comes on with the low beams and not the high beams. If I plug in the relay from the other harness it's opposite, but the fog lights still don't come on. It seems to me that it's the relay under the hood. The plug at the relay get's 12V from the battery, and the voltage from the fog light switch in 10.8 volts. The only thing I can think of is that the 10.8 volts is not enough to activate the relay. I don't know how much voltage it needs to switch. I've ohmed out the fuse and the fusible link is good.

 

the bullet connector you should be seeing 12v when the foglight switch is in the "on" position. if wired correctly

-------------------
the foglights only come on with the lowbeams, and automatically shut off with the highbeams.

the rubber covered relay is an outside relay, the other one has no rubber, and that one belongs inside.

it makes a difference which relay u use, because the one outside is N/O and the one inside is N/C

N/O = Circuit is OPEN without power to the coil
N/C = Circuit is CLOSED without power to the coil

According to the diagram,

the N/C relay (inside) is the foglight controller based on the high beam...

What you originally did was install the N/O relay inside, which caused the foglights to turn on only with the highbeams... becasue when you turned on the highbeam, it closed the circuit, providing +12v to the outside relay...

After you installed a new relay, you should've just switched them...
now your foglights don't turn on at all.

put the N/O relay in the right place.

-------
edit: i don't get it..

if you swapped the relays, how come the foglights aren't on all the time?

okay... i think i figured it out..

you were given bad relays.... and someone didn't give you the right relays...


The bullet connector should show a + voltage, this gives the outside relay's coil power, so it could close the battery->foglight circuit.

I think your inside wiring is correct, as the switch's "on light" (green light) is on when the lowbeams are on...but the switch should still have the glow...

The switch should glow when the parking lights are on.

replace the outside relay with a new N/O relay... preferably with one that is water resistant.... the relay should still activate at +10v

if you are seeing a drop in voltage.. i think that is normal, since the +12v source is wired to the illumination dimmer.

also check that bullet connector, if that is loose, the outside relay would never activate.

oh and if you want the foglights not turn off with the highbeams...

just bypass the inside relay... by jumping or bridging the two pins that are N/C

The relay with the rubber boot is under the hood. I think the interior is wired correctly too because if I check the voltage at the plug before the relay under the hood, I get a constant 12V through the fusible link and fuse from the battery. And I get 10.8 volts that switches on and off with the interior switch. The only thing that confuses me is that the fog lights worked before with the other harness, just only with the high beams. I used the same ground with the new harness. I will check the grounds. I did plug in the "bad" interior relay under the hood and that didn't work either. Which if they are both N/O, then it should have. The only thing I can think of is that 10.8 volts isn't enough to activate that relay, so I will check the grounds and see if I can't get that voltage up some more. If that doesn't work, I guess I can put the old harness back in, and use the new relay but I don't know how that would fix anything. Thanks for all the help so far, I really appreciate it.

 

Your original kit, before you replaced stuff... had two N/O relays

cause they only turned on with the highbeam.

========

if you swapped the N/O with the N/C, then the fogs should've turned once the (-) terminal was reconnected to the battery.

========

If you swapped harnesses... then re-chck all your connections, esp the bullet connector. that connects the outside harness to the inside harness.

the bullet connector should show positive voltage, when the switch's green light is on

========

I thought you just changed the inside relay.
also recheck the outside fuse.

 

OK I fixed it! I don't know how, but the short thick ground wire that comes off the battery terminal wasn't hooked up. It was kind of shoved in between the radiator and the frame. I found a bracket that the other neg and pos battery cables hook on to and grounded it to that screw. Not sure if that is where it goes or not. I don't know how long it's been like that. I am the original owner and I know I never took it off. All of the work has been done at a Honda dealership too. It must have been when we had the timing belt changed maybe, IDK. Thanks again for all your help!

 

Now they don't work again, haven't had time to look at them yet. This is pissing me off!
