so, i went screwing the interior of my car together and i accidently put a screw through the wiring harness for the instrument cluster. i hadnt realised this untill i went to turn my ignition on and my instrument cluster went insane, i turned off the ignition, pulled the suspect screw out, and now parts of my trip computer wont work, for the instant and average fuel consumption it displays "__._" total fuel used does not work, but everything else does. What ive done to try and fix the problem:

1) replace the damaged wiring harness
2) checked for blown fuses with a multimeter
2) used a different instrument cluster

its got me stumped what it could be right now.

doesnt the instant fuel and fuel used show blank when not moving?? have you taken it for a drive?? I assume you dc battery when done so may have reset

yes, taken for a drive, its been doing this for a few days now, even dced the battery after it happened.

What car do you have? The trip computer is in the centre, right?

What cluster did you put in instead & did you replace the damaged loom with the exact same model's loom?

The car is a TF with 3L (and now manual) Ziek has put a TJ S2 cluster into the car.

So, what loom is he using? What's being used in the centre now?

The car has a modified S2TJ Loom in it to suit the TF.
I am not sure which loom it is - all I remember was there being a BIG mess of loom and plugs and stuff...
Zeik will confirm I am sure :)

Yes its a tf with a tj series 2 cluster loom and center display. all was working fine till I put a screw into the harness

I'm wondering what else might be missing from the picture? First is the TF ECU capable of calculating fuel usage? If so, is there a sensor missing or giving a different signal to what the circuit is expecting?

It's just the fact that the rest of the dash IS working and the additional "TJ" features are NOT working.

Time to hit the books me thinks - check for differences in the EFI/fuel delivery components between the two models.

Mate if you need a new TJS2 instrument loom then contact me. I've got one that has only been modified to power & run a TL clock and oil & warning lights - buttons will need to be run seperately though. If you need a clock then let me know and I can source one from the local wreckers otherwise I can wire in the old harness that is for the normal TJS2 centre display (i.e. oil, charge & seatbelt warning lights only). Might be able to get the clock & loom delivered for around $50-60.

You most likely fried the centre disp or similar

Did you check that the red wire still has power and more importantly have you actually driven it since as those parts wont work when stationary

The parts you listed are run by the inject or pulse wire

yeah, rechecked red wire for power, all is good there right up to the combination meter. since i have changed the loom this time round, i have driven 135km, still not registering total fuel/average fuel and instant fuel. i am going to try a completely different cluster unit again, still a tj series 2, just from somewhere else and see what happens

ok, a little update here, i have tried a completely different TJ series 2 cluster, drove for around 100ks, still no difference, i rechecked for ign power to both the center display, and the actual cluster and its present at a little over 12 volts, i rechecked for voltage of the #2 injector to the cluster with the engine running and its there too, but its reading at a little over 13volts at idle, im not sure if this is right though, i figured being an injector it should be a sliding voltage depending on how light or heavy you are with the accelerator. so i went engine side and checked the voltage of all the injectors, and i get the same reading at idle....is this correct voltage?

by the way, the voltage on the injectors does not move when i rev the engine up

The injectors are switched with ground and the power is there all the time

You can not check a pulse with a muti meter, only can check the power

Have you tried a different harness, there may be damage in the harness you can not see, I would start there

yeah, using another harness, i put that in yesterday. on saturday im going to check my 2 clusters i have with me on a friends car, i figured the chances of getting a buggered cluster from the wreckers is a 50% chance, considering i more then likely buggered the first cluster with that screw. appart from that the car is running smooth, and there is no signs of any electrical damage causing other things to malfunction. also on a side note, this second cluster i tested was dropped by the guy working at the wreckers lol

so, today i just tested a 3rd tj 2 instrument cluster from a completely different wreckers and i still got the same problem, i even dced the battery for a recheck, do differance. when im mobile my inst fuel displays a 0.1 / total fuel __._ / avg fuel __._ the things that i have done to try and rectify the problem:

another modified TJ 2 wiring loom to fit TF exec
3rd instrument cluster
checked for power to the instrument cluster and center display (power source is from my rear dimister switch)
checked power from #2 injector to display (all i can do is check power)
checked for blown fuses

my car is a TF exec magna, manual conversion, now a TJ 2 cluster conversion. i got the wiring setup from mal so i know thats correct to the ECU. im running out of things to check here lol. im starting to think maybe i spiked something in the ecu with that screw

I think you need to check all your fuses again as those wires you have done have nothing to do with the trip function

Did this ever work to begin with?

Also, NO you did not get the wiring from me, you called me and asked me to do one, I was stupid enough to give you an idea of what you would get for your massive cash injection of $60, you then decided to try to do this yourself and then spent the rest of the afternoon calling and emailing me questions, when I stopped responding you then got another member to start messaging me instead so dont even think to bring me into this fiasco you have created for yourself.

WTF.......i phoned twice asking where those 2 wires went, your just upset because you didnt make money out of it. as for me getting another member to message you, he did that on his own. your making it out that i harrassed you all day long. close this thread, im not in the mood to be flamed by some moderator who thinks he has the power to flame

WTF.......

For starters sunshine, I am not a Moderator, I am a sponsor of this forum

Secondly, in your post you inferred I DID THE WIRING FOR YOU, I did not do this for you as you well know.

Third, I was also in the start of that post offering more help so if you are feeling guilty about not getting this done then dont cry about it here!!!!!

Fourth, "Has the power to flame" again WTF?, I SIMPLY MADE A COMMENT in reply to your stating that I had done the harness which I did not. Truth is not flaming someone so grow up and stop being so precious.

True you were not stating I had done the harness wrongly but either way, I did not make your harness so you dont even need to bring me into this discussion. Despite you gleaning information out of me and then doing it yourself (and some wonder why I usually dont give out this information) I have still on numerous occasions attempted to assist you in this very thread.

As far as I am concerned now, stiff bickies, you were stupid enough to ram a screw through a wiring harness, dont bother asking for my help sunshine as you have burnt this bridge to the ground....best of luck fixing this as I think you are going to need all the luck you can get if this is the way you treat the people trying to help

Oh, and I have spent the last 45 minutes on a car I have here working out what would cause your issue with the inst fuel at 0.1 and the rest blank, found it pretty quickly but I guess you will just have to work it out for yourself now after all, why should I spend my time trying to help someone who does not appreciate that help

[QUOTE=Ziek;1451465] i got the wiring setup from mal so i know thats correct to the ECU. im running out of things to check here lol. im starting to think maybe i spiked something in the ecu with that screw


when i said i got the wiring setup from you, i was meaning where to put those 2 wires. maybe i should have been more clear on how i worded this, but on my defence, i have had my head stuck up a magnas ... checking the fuses. i didnt mean to bring you in to this, didnt even mean to mention your name, i was just stating the procedures i had already done. as for being "precious" im only that when im not drinking. growing up is not an option, im too old as it is. and i always appreciate help
