Dashboard Warning Light Help
Hi can anyone tell me what this means? I just picked up my JDM itr and this light is on all the time but i can't work out what it means.
Picture is out of my JDM owners manual.
Also the car is not running well below 3k and seems to be over fueling when accelerating hard. I think this could be down to the unleaded fuel the import guys are using. I've since put in some 98 ron fual but have not yet noticed a diff.
Any help would be fantastic.

Looks like a muffler with heat coming from it, so since the only part of the exhaust that has a sensor is the cat I would assume it is?

Re: Dashboard Warning Light Help (ibme_uk)
That is the cat light.That normally comes on when ,or when you have a small leakage of exhaust from the front collector to the cat or the sensor in the cat isn't earthed good(have rust).

Re: Dashboard Warning Light Help (ibme_uk)
Thanksf for the info, I guess the sensor needs checking... the car has just passed sva and mot in the uk so would think the cat is ok
Is this error going to change anything in the ecu i.e will affect how the cars going to run? i.e could it be the problem i am having at low revs?

Re: Dashboard Warning Light Help (ibme_uk)
Just an update,
Taken the car to honda uk so they can check it out, they could not read the ecu with there equipment so they give me a lovely honda jazz
till they sort the problem out.
The light on the dash is either o2 or cat over heat (i suspect the cat) and they belive it could be the cause of the poor performace i am getting.
I'll update again once they find the fault and have the car running as it should be.
The Car in question, currently in the hands of my local honda dealer

Update on the caR (ibme_uk)
Just had a phone call from Honda uk and they can't find out why the light is on, turns out the ecu has had another chip installed that is stopping them getting fault codes????????
There going to adjust the tappets and change the oil, hopefully this will sort out the rough running.
The car seems to run worse when its warmed up????
Anyone know what this extra chip might be?

Re: Update on the caR (ibme_uk)
Ther is no other chip on a jdm ecu.
You might have a clogged cat.Try to remove it and put a test pipe.Once i had this problem but in my country in malta we can remove the cat and make a test pipe.I had the sensor loosen or rusted,i just removed the sensor cleaned it and tighten again

Re: Update on the caR (JDM97R)
Strange how they cant get pick up fault codes although I know it isnt throwing a CEL, sounds like Honda cant even get to the diagnostics on it, which is strange as even if its JDM/96 Spec they should be able too.
Unless you have some obscure ECU in there or ECU Upgrade of some kind. that would maybe make sense, perhaps that is what they mean it might have some piggy back upgrade on it???
Shame your not up in Yorks cos you could try my standard ECU.
Adjusting Tappets & Oil sounds like a stab in the dark in my opinion, oil shouldnt make it run badly, unless it has none in. Tappets would just be really noisy they wouldnt impact massively on the way it runs, IMO.
All i can say is dont panic too much, these things just take time sometimes.
When was the last time the car was running ok?

Re: Update on the caR (benmasters)
Also dont worry about fuel type too much, the car should compensate if anything, if the car was designed for a 100 RON and you put 96 in it, it shouldnt impact on its running, you will maybe just lose a little power, but you wont know the difference if youve never had 100RON in it. Check the timing you should be somewhere 16 +/- 2degrees being JDM its probably set at 18, thats what I would expect Honda to be doing.
It sounds to me like an electrical problem, something has come loose, broken, sensor has gone or as JDM97R said clogged or dodgy CAT.

Re: Update on the caR (benmasters)
I only picked the car up on sunday (yesterday!).
I've instructed them to change the oil as the stuff in there was looking bad.
They suggested the tappets (I also think there taking a stab in the dark) I'm going to get them to also check the timing as it feels like it could be that to me. As the car is having problems reving freely, partically when its warmed up. Seems better when its cold???
I understand that some cheap piggy back chips block error codes? as far as i know honda can't get anything out of it. They said they have tried a couple of methods.
I will keep an eye out for a cheap ecu to try (also thinking of a hondata s200 as a possible replacement) and see what this extra chip in my ecu is doing to the engine, my worst concern is that this chip'd ecu has been incorectly mapped and may be causing over/under fueling or something???
If the timing is ok and the tappets are fine I guess I will try and bypass the cat to ensure that its not that causing the problem.
Only problem is that Honda are going to charge £60 +vat for any work they do. Tappets are an hour and oil is half hour already.
On a possitive, the v-tech is working fine and the cars pulling hard (well as hard as it can in its current state, I've stopped driving it till its sorted as i don't want to cause any damage to the engine.

Re: Update on the caR (ibme_uk)
I think the ecu is ok coz with the cat light on ,the cel is off.
You have to put the distributor timing at 14degrees coz of the sh*t fuel like in my country.The oil change and the other stuff you said are a waist of money unless you have to do an oil service but for the cat light is useless .If you want to check the stock ecu,the jdm has a speed limiter set at about 180kmh.
IMO you don't have to worry that much about that light,just check the cat and double check all flanges that they are all correct tighten and recheck the sensor in the cat for rust as normally it has alot

i don't think you're understanding. although his cel is off, there is no way to check it because it is somehow blocked. he mentioned that there is another chip installed and that they tried a few different methods of checking the cel. this can be a problem later on and he has no idea what chip is installed. my suggestion to the original poster is to do all maintenance items and fluids. also, a new ecu will probably save a lot of headaches later.

Re: Update on the caR (nightrider)
After some thinking about how the car has been running ie
poor at under 3k
ok ish till v-tech at 6k
pulling very hard at 6-7k (feels like a turbo to me)
This leads me to believe that the inlet and exhaust systems are flowing ok, otherwise surely there would be more of a problem at higher revs than lower?
I appreciate that I have not been driving an ITR for more than a few hours so far, so I could be under estimating how well the car runs at 6k + but once it hits 6k it really moves till i have to change just before the red line, in both 3rd and 4th gear.
I'm putting the cat warning light (only found on jdm cars according to Honda uk) down to a faulty sensor or connecting wire. and the poor performance down to the timing or tappets, however this may be a stupid question, what would cause either of these to be so far out?

Re: Update on the caR (CivicFerioViRs)
Another Update,
Just been and spoken to Honda and the cars still the same, running poor once it has warmed up.
They have checked the timing and adjusted the tappets.
The next option is to try an alternative o2 sensor which will cost £230 if its faulty or £40 handling charge if I don't need it.
If this does not sort the problem out they suggest the next step to be a replacement ECU!!
which if faulty will cost me £1000 or £150 handling charge if its not causing the problem.
I guess that if the o2 sensor is ok then i will have to get either a replacement OEM JDM ecu or an aftermarket replacement?
It seems the more that's ruled out the more expensive this is going to be to fix!
The Jazz if really starting to do my head in I need the R back soon!
Anyone got any ideas what could have been done to the ECU to stop it giving error codes? and can this be undone? i.e if an eprom has been added can it be taken out so the ecu defaults back to the OEM mapping or is this lost for ever?

I think you have a run rich chip in that ecu and its trashed the cat... Pull the cat out and install a test pipe to see if you get a better run out of it and get a stock p 73 ecu back in that thing. Also check to see what temp thermostat is in there if its set cold this will also make a run rich problem. ( which will pack up a cat)

Re: Update on the caR (Rene M)
That sounds interesting above.
O2 Sensor - just go for an after market, dont pay OEM prices, do a search on uk forum I think some folks have bought aftermarket o2 sensors for like £40 - I seem to remember one guy getting a new one from his local motor factors.
Found it :-
on your advice, i went and got a 4 wire universal oxygen sensor (LUCAS) from an autoparts store, cost me £54. fitted it (with a little wire joining to the oem electrical connector) in about 20mins and totally cured the problem. in doing this i saved myself nearly £250 on the original HONDA part. car flew through the MOT today and the emmisions were low enough for me not to have to swap my de-cat pipe/manifold for the originals!! jobs a good-un! fuel consumption has decrease dramatically too. cheers ..a now happy ITR driver

Ok this makes sence, could explain the cat over heat light. I'm doing my hardest to source a direct replacement OEM ECU as i think this need to be done now to ensure I have no further problems and restore the error logging.
What do you mean about the thermostat? how can i check it?
The car pulls really well at high revs would that still be the case with a trashed cat?
Off to hunt down an ECU. will let you know how i get on with the o2 sensor tomorrow if honda get one in by then.

You will have to take the current thermostat out and have a look, it might have something written on it indicating if its an aftermarket job, I have a old OEM one at home cant remember what markings are on it but I can have a look.
I think the mugen ones run cooler, if it is replace it, specially for UK. If you have it out it might be worth replacing anyway they dont cost much and they are easy to do - replace the coolant while you are on as well.
I have a document listing how to do the above can send it to you.
