Computer flashes tail lamp failure and my tail lights and liciense plate light all work. what is the problem?

no (park -tail-running lights) is dash parking lamps glowing?
check the tail fuse yet?
94 accord
this circuit is huge, park/tail, up to 20 lamps. are all dead>?
front park, side park, tail park and dash lamps all out.
this i the red-blk feed. all comments , USA, as lighting varies by country. (laws)
license plate light dead too????????? that too is park
there is NO RELAY.
the fuse 32 feeds the HL (head light) switch and in PARK posistion
it feeds 12vdc raw power to all 38 lamps. (side corning lamps,etc)
the license plate lamp is key, there are 2 lamps.
and both probably are not out.
so if they are good lamps and both tail lamps are good and fuse
then they must glow, if one lamp shorts as 1156 or the like love to do
then it blows the fuse. as does the trailer jack (option) .

so fuse 32 park/tail blown
or HL park switch bad, if all 20 odd lamps dead. and fuse holds.
that simple, and this cars wiring is very simple and nice.

that line on that fuse is shorted, the fuse saved the fire.
we use an ampclamp DC ammeter to find the wire that is shorted
and the actual point of short.

the park-tail circuit (tail fuse, right) is the most complex of all.
20 lamps inside car, and many out side, it is the hardest to find of all shorts. but not with the tool
first check for damage behind all park lamps
i bet the fuse blows in park (1st click) not head lights. right?
side lamps the 4 front rear park lamps, some call it tail its not really tail now, was in 1920 ,not now. park is everywhere.
but the fuses can be marked tails, for fun .
imagine, calling the 2 front lamps tails. and are on .(my on going joke)
sidelamps,
the inside lamps are many too.
all dimmable lamps. so turn the dimmer down to zero and see if fuse blows now, NO?, bingo.

the best way to fix this is , visual inspections for collision damage or wire hacks in the cab.
then the fuse is pulled and circuit breaker inserted 15amp
(they sell em)
then we connent the ammeter to the wire (output of fues)
i push the switch and amps goes to infinity and the CB trips
if follow the cables, and find what line is shorted.

i missed one problem
on the rear or front 4 corners of the car may be twist lock blubs.
like 1157 or? these love to short. push in lamps never short.well not the lamp actual.
in not sure what lamps the 06 uses, but replace the brass based lamps. (in park tail ckt)

If you have the wrong style bubls in the car it will cause this . Their is what is called european bulbs that have a silver base ( the style you need ) an the USA bulb which are brass color . these are the ones that will work but set the failure light off .

The fuse for the tail lamps is located in the Instrument Panel Junction Block under the left side of the dash behind the lower finish panel. It is marked "TAIL" and it is a 10 Amp fuse.

HINT: If this fuse is blown, your front marker lamps and your license plate lamps will also not be working.

If you are having a problem getting your tail lamps to work, The common problems on your vehicle is bad grounds inside the tail light housing. They tend to get loose at the rivets that hold the light socket and the ground wires to the plastic housing. I have fixed many of these by drilling out the rivet and drilling a small hole COMPLETELY through the tail lamp housing at the rivet location and installing a long, skinny bolt with a nut and lock washer to re-mount the light socket and ground wire.

Another possible cause is a failed rear lamp warning module failure. If your tail lamps are not working and the rear lamp warning light in your instrument cluster is not lit, then this could be the cause.

There is a harness that you unplugged for the rear tail lamp. Make sure it is fully pressed and locked. This is always the cause on jags for tail lamp failure.

1. Tail,Plate and panel lamps all work off the same fuse
2. do you have a trailer lamp kit on the cruiser?
3. check condition of trailer lamp wiring under rear
4. if not remove and inspect all tail bulbs and their connections
5. has anyone installed an aftermarket sterio setup possibly running a screw through a wiring harness?

Hi
There are a couple of wiring diagram and manual available on the net. The relay you are talking about is the park lamp relay which supplies power to the tail lamps, license plate lights and both front and rear park lamps. If the park and plate lights are working the light switch, relay and supply power are good. You need to verify for a broken brown wire to the tail lamps (assuming the sockets, lamps and grounds on both tail lights are good) .If none of the lamps are working then the 15A fuse number 3, the light switch or the park lamp relay could be bad (note different contact in the main light switch work the other lights)

You can find a wiring diagram and component location at
www.autozone.com and http://www.pdfgeni.com/book/1998-ford-ranger-wiring-diagram-pdf.html

Let us know if you want something more else accept the solution.

you do have a tail lamp relay,

CHECK TAIL LAMP BULBS AND THE GROUND FOR THE TAIL LAMP ASSMBLYS

Sounds like you may have a wiring issue. I would cut the wires at the tag lamps, leaving enough to splice in new ones. Then pull one of your tail light assemblies out and, using a test light which is available from most parts stores for $5-10, figure out which wire is hot with the parking lights on. Splice a wire from there to your tag lamp socket. Then splice the other wire to the ground circuit at the tail lamp or find a good ground to wrap it around somewhere else (usually just about anything metal). Just find a bolt somewhere, back it out a bit and stick some of the stripped wire behind it at tighten it back up.
