Remote Start / Interior Lighting issue

x

 

I think you kind of stated it here, but I just wanted to make sure

ok, once they are off. even if you start the car with the key, and turn on the parking or headlights, they are still off?

because imo, everything you are saying is normal, other than the fact that you can't turn them on in general

 

ok yea that does sound like a problem then, it's weird because I don't think any wiring should go to the AC unit or the shifter lights specifically, I have the same exact viper alarm, and when they are on, is when the parking lights are on, Also, since you say it's only recently been acting funny since you messed with your stereo, I would think if the bulbs inside got dislodged, your problem wouldn't be so consistent. I don't think this is the problem, but the only thing I can recommend is check that your gauge lights are not turned all the way down, near the speedocluster

 

Sounds like a ground issue with the remote start unit. I'd disconnect the parking light wire from the remote start unit and check to see if the problem persists. Because it sounds like the parking light switch is only seeing ground when the remote start is activated.

 

A simple problem solving exercise:

1.) You had a Viper Installed a few months ago.

2.) It has been working fine with no issues since.

3.) You installed a LED bar and messed with the head unit.

4.) Now, The lights behind the gear shifter (D, R, N, 1, 2 etc) and the lights behind the climate controls are acting funny.

Seems pretty simple to me when you did the light bar and or head unit something got mucked up. If it was fine and then you did X, Y or Z and now it doesn't work properly. Chances are pretty damn good that X, Y or Z caused the problem.

Check this first: It could be that you pulled something loose on the viper wiring when you were behind the stereo head unit messing around.

MY next step would be to unfuck the light bar and or head unit messing you did and you will more than likely fix your problem.

It is not a Blown Fuse. With a blown fuse the lights would not come on at all.

 

just drive with your headlights on

 

The way it sounds your parking light wire is open circuit (oem wiring). Because when you start the truck with the remote start the parking lights work because they get the ground signal, for the switch, through the remote start unit. Meaning when you try to turn on the parking lights with the oem switch the circuit is not complete.

 

oh that was meant instead of your running lights, just turn on your headlights so you dont get pulled over

 

Did you follow the simple problem solving exercise that JimmyH posted?

Spend your effort doing that, instead of making sure every reader has a clear understanding that you can't operate your headlights via switch.

 

By running lights I assume you mean day time running lights? My truck doesn't have DTRL and yours probably doesn't either. Especially since you changed out your headlights. If your truck does you should have more than 3 options on your headlight switch I believe, then you have to wire your headlights in correctly. How'd you manage to get pulled over for that? lol.

 

You must have blown a relay. If you don't know how to check them with a meter, swap it with another one to verify.

 

just want to make sure you're checking ALL of the fuses.

there is a fuse box under the hood and another one behind a door to the left of the steering wheel.

also how are you checking them?

so everything works until you hit the brakes? then you lose tail lights and some interior lighting?

 

Not a fuse....

Did you even read my post above. Logic is a friend. Use it.

or

Keep running around in a circle with your hair on fire.

 

Looks a lot like you're directing that at me...

I agree that typically a blown fuse will not show signs of what he's experiencing. I'm asking details to understand how thorough he is and if he knows what he's doing... hell he said he blew 2 fuses just installing a light bar.

visually is not always good enough.
invest in a volt meter or at the very least a voltage tester.

you just clamp it to a ground.. usually any bolt on the vehicle.. and touch the tip to the metal contacts on the fuse near where it says how many amps the fuse is rated for.



toyota does some dumb shit so i don't like to assume that their wiring is always cut and dry. I do think a relay could be the problem but grounding or a loose connection could be an issue too

 

I'm hoping you just simply missed the first post where the OP says the headlights DO go on, but only when started by the remote. Once in drive, they shut down and will not go back on... even if the switch is on.

Checking continuity of the fuses will get the OP nowhere fast as the headlights do work at certain times.


I don't know and the OP didn't say where he got power from to wire his LEDs.... that could be part of the issue too.

OP, where did you tap the power from??

 

It's a sure bet that if you pull wires out of your Viper unit, it will not work.

Auto starts are also wired to the headlights or parking lights to indicate the engine is running.... it is bypassed from the headlight switch. There is no need to aimlessly screw around with the functioning Viper installation.

You have since disconnected your lightbar and the headlights still do not work as intended..... you have a bad relay.


Good luck

 

Disconnect the illumination wiring to your head unit. Are you running the LED lights on a separate circuit, with relay, switch etc? Put it in reverse on your troubleshooting!

 

Headlights work?? I was going by the 1st post. Oh well.

If you wired your lightbar to the battery from the beginning, you would have no problem.

If you fucked with your remote start wiring/ installation in any way, that is the problem.

 

I have the same remote start on my 2012, that is all normal operation with your remote start.

 

Check the relays under your hood in your fuse box.
