Tail Lights not turning off
 

Hi all,

Can't seem to find any post of anyone talking about this issue. My tai lights are staying on 24/7 even when the lights are on 'off' mode or when automatic is running at daytime mode. Tried resetting the computer by pulling the battery but no go.

Anyone know of a fix?

Thanks!

Hey Jus,

Old school issue is maybe your brake pedal switch is bad, and is closed all the time? I know you said tail lights but maybe you mean brake lights?

Any mods to your car? That's usually the first question, like, "What's the last thing you did to your car before this happened"?, etc.

Is this only on rears?

Hey,

Don't think it's the brake pedal as the Burke lights go on normally. It's really just the tail lights that stay on at all times. It's only on the rears. Last things we did were just body mods like skirts so it really shouldn't affect it at all.

Only thing I can think of possibly is the uprev tune? Not sure if that would affect it though? Other than that not sure how to fix it.

Do you have Nav?

And have you tried disconnecting the battery just for shitz n giggles?

Yes I have nav and yes I mentioned how I disconnected the battery already but still no go

Didn't see the battery part.

Assuming you mean OEM Nav, have you tried going through the Nav settings? I know you can control when the lights turn off through that

I would suggest to check you don't have something blocking the Light Sensor on the passenger side of the dash nearest the wiper.

Or you may have a BAD light sensor.

The sensor controls the lights to come on automatically when it get dark.

Have the dealer check to see its working correctly or see if its something else

Where in nav settings can u control when tail lights turn on? I know and have tried changing the sensitivity on the automatic sensor but that has nothing to do with it. =(


If it was just the light sensor then the tail lights would still go off when lights are in complete off mode but they do not. Also if it was the light sensor affecting it to stay on 24/7 then the interior switches would also stay on 24/7 but that is not the case. They still come on / off like normal. I've checked and diagnosed every normal thing. It's not that simple.

Last resort is getting the dealer to check but I just thought with the mast amount of members here someone might know.

There's like a time off setting, if I had my car I'd walk you through it.


PM me your phone number

I know the time off setting but what does that have to do with the tail light not switching off? It's only there to adjust the duration the light stays on after turning off the car no?

Yeah, but if its switched to unlimited or something, maybe that's your problem? It's a timer from when you open the door to get out to when you close it (if that makes sense)
Lets say its 90 seconds. You drive home, turn off the car, get out, close the door, your 90 seconds starts from that time.

Lol how does that have anything to do with the taillights staying on?!?! That's just the timer for when the lights completely turn off. Doesn't affect the tail lights when the car is ON. Thanks for the help but you sure you know what your talking about dude?

No ideas anyone? :(

Sorry, it's a common problem with Canadian Z's... the brake lights stay on if your blinker fluid is low.

That sounds very helpful... Let me go try this and let everyone know ;) Thx!

I don't have DRL nor have I seen the drawings/schematics, so take this with a grain of salt. It sounds like what I would expect to be normal behavio(u)r. Even if it's not, it sounds like a good bug undocumented feature from a safety standpoint.

It doesn't appear that anyone else knows, either. I suggest digging through your Owner's Manual and/or contacting a dealership.

might be a stuck relay. thats just a wild guess, though.

So after checking everything nothing is wrong. Took a look at the wiring diagram. Looks like the 'daytime running switch' is connected directly to the rear lights meaning they never actually turned off! Lol... just never noticed it? Can anyone else confirm?

Link to schematic/diagram?

NEVER turns off?

Or isn't off while your DRLs are on?

Don't have the diagram/schematics but thats what it showed.

The DRLs are always on here in Canada so I guess yes, NEVER turns off in that sense?

Yes, I know, I'm Canadian myself.
I thought your issue was that they wouldn't turn off even after the car was off. That's how your OP read.


If they're just on while your car is on because of the DRLs, I really don't know what to tell you...

I guess bottom line is, does your car's tail lights/lisence plate lights turn on 24/7 even when you're in the "off" position?

No, neither are yours. Yours is on while the car is on.
While your car is on and your are forced in Canadia to have DRLs, I don't see why it's a big deal that your license plate and tail lights stay on, because in effect Canada's "off" if a car is even equipped with an "off" position, is like leaving the car on the parking light mode, and in that setting, the parking lights, tail lights, and license plate lights on most cars are on.

I see a connection.

Actually that's not true. Most cars I would say 80 or more percent even with DRLs in Canada have a "off" mode in which ONLY the DRLs stay on. If you look at our headlight switch there are 4 settings:

1. OFF
2. AUTOMATIC
3. MID-DAY
4. NIGHT

Then midday setting is supposed to turn on the rear lights but not night time lights in most cars. The fact that our car's DRLs is the same as night time makes that extra position completely useless. Mode 3/4 would be EXACTLY the same and the only diff between mode 1/3/4 is the interior illumination then. If this is really the case that's a really dumb design. Dunno y I just noticed the taillights always stayed on until now lol.

Do you have auto starter? If so try clicking the lock button on you keyfob few times to take it out of the mode that’s keeping the lights on.

You used your 1st post to answer a 6 year old thread?

I had the same issue recently, the light won't turn off until running out of battery.
My car also happens to be a Canadian version. The light is stuck on MID-DAY mode forever but the light switch is on OFF position.
Does anyone have any idea which part went wrong?

Legend has it that OP is still in the process of topping off the blinker fluid and will let everyone know.

If your tail lights are stuck on you probably loosened the box on the top of your brake pedal with the white wire going into it. Just push it down in and it might need a little twist to lock into place. I found the answer on the 350z forum, it worked for me.
