Door Sensor On?engine Hardware Fault?

[bumble_bee]

hey i drive a '96 r33 s2 sky...bout a few weeks ago..i notice my door light on the dash does not go away..

and yes ive checked the door switch on the roof..and both switchs on the door frames..but no luck...

plus i heard that nissan sometimes the ecu will display lights on the dash wen thers a fault..etc..

any ideas would help..thanks

Ive just noticed the same problem on my car. I had a look around at all the fluids and noticed that my coolant was low. but i havent filled it yet. gotta buy some first thing tomorrow morning. then ill tell ya what happens. I have a 32 GTR so things could be different.

[jwah]

I had a stuff around with my car today and yeah cant find the problem. the hicas fluid was low but yeah the light is still on. so maybe its just a faulty door thing. I noticed when i turned the interior light on an off a couple times itd go off. but that stoped working. If ya find the problem let us know

Cheers

I've got a similar problem with my car. Red 'door open' light and the interior light flashes on and off, happens more over bumps, or under hard acceleration. I'm assuming ive got a loose wire in the boot, which runs from the boot to my alarm. i've seen my red door light dim and fade, so its not like a switch flicking on and off - but more like a bare wire earthing somewhere.

Good luck finding your fault, have you tried pulling apart both door switches? Also check if you've got a bonnet-pin switch (possibly fitted by alarm installer). Finally check boot switch which is inside the lock mechanism, in the boot lid.

so r33's have a boot switch in the actual lock itself????

...k i give it a look..

coz i did notice that my boot light stays on!!!

i can c the light beam onto my rear window at night...

so i had to remove the little wedge globe..

and ive had it out ever since, plus my interior light is always set to off..otherwise the light will remain on forever..lol

and ive had this problem for a while..

maybe my sub going off knock a wire lose or sumthin...

i checked the bonnet alarm switch, seems fine, and i gave it a clean wit electrical contact cleaner..

and i checked both door switch pressed them in and out, took them off etc..

no good, door light remained on, and interior light will still remain on aswel...

but i tried finding the switch for the boot but no luck..and no one knew either...

but yeah..thanks

but i'll take a look =)

does the boot lock have a wire coming out of it or anythin?

and its on the boot lid on the actual lock on the rear panel???

more information on this would b great..

thnks

From what i understand, if you open your boot, the boot-switch will be in the lock mechanism on the boot lid (not on the car chassis itself) You'll notice a black rubber tube on the right - the electric wire runs through there. This is what i've been told, havent had time to pull mine apart yet.

i would check the two door switches first, as they are whats connected to the light on the ceiling. if the ceiling light is flashing on, its because the switch is opening on one of the doors and you have it set to "door".

set the interior light on "door" and have a play with the rubber buttons to see if they are working or not

alarms usually have their own boot/bonnet switches that are in no way connected to the doors.

alarms usually have their own boot/bonnet switches that are in no way connected to the doors.

Hrmm every car i've had, the alarm has always used the same boot switch. The alarm taps onto the common 'door' circuit, so that when the circuit goes to ground, it triggers the alarm.

Bumble_Bee - have you tested your alarm to make sure its working? Try arming your car with the windows down, then unlock the door an open it to see if the alarm sounds. I wouldnt be surprised if your alarm isnt working at the moment which could be of concern!

[bumble_bee]

umm..ill check it out but im pretty sure its working..

um.. i did found two wires under the boot lid carpet..which go to the lock..

and the black rubber tip on the end is kind of worn... :|

is it spoz. to have any metal exposing on the tip of the boot lid lock?

because it looks like on mine that the black rubber tip/cover has worn off...

but can anyone tell me wat these two wires to do?

[Trav33]

This is what mine looks like. You can push a screw driver in to simulate the boot closing, and should see your boot light turn off.

Does yours look the same as mine? There is a black plug half way up the boot, if you think the lock is dodgy, disconnect the plug.

[bumble_bee]

yeah, mine looks the same..

but y wedge a screwdriver into the lock? lol

i dont think the lock is earthin correctly on mine...

so mayb if i could figure out how and y?

i could fix it..

mayb i should try earthin one of the wires...

but i unpluged the harness but nothin..

problem still there...

wat do u think the earthin point is on the lock?

[Trav33]

If i had your car, i'd now start looking at the alarm wiring, and maybe take it to an autoelectrican! It sounds like you've determined there are no problems with any of your boot/door switches.

[bumble_bee]

yea..i was thinking that but me and my mates still recon it that in my boot lid...

wen u unplugged ur harness does ur interior light/door light turn off??

[Trav33]

When i put my screwdriver in the latch, the light turns off.

I imagine if you unplug the harness, the light should turn off too.

However if you have something on the 'door circuit' which is grounding, even if you unplug the boot switch harness your lights may stay on, becuase the problem is somewhere else, not there.

[bumble_bee]

oh ok..wel i'll try wedge a small screwdriver into the lock..

like the picture u took..

and c wat happens..

[bumble_bee]

k, tested my alarm..

thats still works

gota be a door sensor, that boot lid lock assy, or the interior door light assy.....

[bumble_bee]

k, defiantly found the problem...

THE PROBLEM!!!!!!

the guys who fitted my alarm did some re-wiring coz of the features of alarms these days..etc..

well on the driver door switch..theres 3 wires...anyway i never took the panel behind it off before..

anyway..i had a look and found that they soldered two extra wires which go the back of the car..dont no wer too?

possible the rear ilt/shock sensors???

and way i tampered wit it and taped it up better..and now it seem's all good..for now..lol

so it was the extra new wires connected to the drivers door switch...

i have no idea wat that switch in the boot lid does..lol

HOW I NOTICED THE PROBLEM!!!!!!!!!!!

and i only really spent time on it today..coz of last nit..

my alarm went off like 4 or more random times...by itself..there was heavy rain and strong winds..but who knows..anyway then..

today at work i saw my car..just go off...for no apparent reason..lol

wen it wasn't raining or any type of wind...

and dis-arm itself and did it like 4 times in a row..and all random times...etc..

and so to stop it i hand dis-arm my alarm..and my car was unlocked for the whole day..

anyway i got into my unlocked car after work and realized for the first time in like 4months when my key was in the ignition..that the door light WASN'T on..lol

then i drove for like 10mins on my way home and noticed the light had re-appeared!!!!!!!

anyway..i opened my door at the lights and re-closed heavily with anger..lol

then i notice it disappeared again..wat the???

then again like 5mins after..like going around a round-about...

i saw it re-appear once again...

closed my door heavily once again..and it was gone..

so i def. knew it was my drivers door switch/ or the wiring!!!!!!!!!!!!!!!!!!!!!

and it was all that time..the wiring was loose...lol

and getting knocked around in the "b pillar" panel and the interior trim...

so that wat was setting my alarm off and on..the wiring earthing or re-connecting a live circuit...

and hence my alarm thinking someone opened the damn door!!!!!!!!...lol

i tht i was in need a of a new battery..but my battery was pretty new..so yeah

this all came to me today...

PROBLEM SOLVED!!!!!!!!

So if anyone get or has a similar problem like i have had....

i hope this helps!!!
