Hi guys ! Car running not-so-hot ? Most of our cars being Electronically-fuel-injected...any problem that can happen to our vehicles is usually derived from a malfunctioning sensor SOMEWHERE along the line.
So...here is a normally sure-fire way to quickly test your cars ECU , for any ECU codes which can tell of problem areas.


Aim: Here is a normally sure-fire way to quickly test your cars ECU , for any ECU codes which can tell of problem areas - of which is quick , easy and inexpensive which anyone here can do :)

Required: Yourself...and a small paper clip or similar object - such as a length of audio wire , tweezers etc.

http://tech.ozhonda.com/diy/eg_ecu/IMG_4391.jpg
As shown , I have choosen to use a paper clip stretched around to make a nice lil connecting handle of sorts.

Steps:
First , produce the DIY connector pin.
Next , place keys into your ignition , turned completley OFF.

Locate the 2 wire connector , located in the left-hand-side , inbetween the ECU location , and the bottom-left lip of the glove compartment.
http://tech.ozhonda.com/diy/eg_ecu/IMG_4394.jpg

Pull yourself underneath this are as it will be alittle hard to locate - look for a large bright green *shown* connector holder - and pull out the connector with the 2 wires , one been brown , and the other is green and white.
http://tech.ozhonda.com/diy/eg_ecu/IMG_4393.jpg

Next , place the DIY clip-connector into the 2 small bottom holes of the connector - completing the circuit and enabling the ECU's scan mode.
http://tech.ozhonda.com/diy/eg_ecu/IMG_4395.jpg

Finally...places your hands upon the ignition key- turn to ON *not start* - as you usually do to enable the fuel pump etc.
http://tech.ozhonda.com/diy/eg_ecu/IMG_4397.jpg
The engine check light should now come on either numerous times , or hopefully not at all - signifying one or more ECU codes that your engine is currently experiencing...letting you source the problem and replace say a sensor before it costs u alot of $$$

To READ the codes , observe the amount of "blips" and type - for example , a code 6 *ECT* would be like - "...blip...blip...blip..blip...blip...blip...STOP" *repeat*


A code 23 would be ofcourse 2 long blips followed by 3 single blips in a row , then a short pause before repeating OR throwing another code.

IT is perfectly possible to have multiple codes - for example - code 3 + code 17 + code 6....would be represented by 3 blips *PAUSE* then 1 long blip then 7 short blips *PAUSE* then another 6 short blips. *repeat*


Other comments
Below , is the basic codes relative to MY civic - and pretty much most hondas from 92-00.

If in doubt...take it to a mechanic !

if your warning lights havent come on and ya cars still running crap then the ecu wont have any errors logged and so I think would likely show you nothing.

ECU-MAN
21-08-2004, 10:18 PM
great work Ben. this should be checked every service. not only for the PGMFI health but more so to see if any codes apear in the SRS, 4WS, ABS systems.

I've read that 3 times and i'm finding the comment very vague!?!

The above mentioned ECU does not 'log' any errors, but rather it is a self diagnostic mode used for......well diagnostics.

bennjamin
22-08-2004, 01:13 AM
to add....most of these "diagnostic codes" are not known until you actually log onto the ECU via this DIY way or on a actual diagnostic tool.
More so the point of this - is to diagnose problem areas before they result in greater things i suppose.

sorry to be vague..

I meant that a faulty sensor will throw an error on your ecu.. then you will see your warning lamp lite up.. once its lit then you can follow the above procedure to discover what is actually wrong with it. If the warning lamp isnt lit then the ecu has not detected any errors including sensor failures.

The procedure above doesnt actually force your ecu to run through a series of diagnostic tests but instead it makes your ecu display errors logged from detected sensor failure during operation. Or other failures for that matter.

I'm pretty sure this is how it works.. the procedure is great though!.. I have used it myself to diagnose my 4WS probs. The 4WS prob is an example of where the warning lamp was already lit and the procedure above was used to diagnose why it was lit.

Hence (provided all dash light bulbs are working) if you dont have a warning lamp already lit up on your dash then the procedure above wont really do anything for you.

Also remember, after fixing the source of the problem, you need to reset your ECU to loose the CEL code

depends, if you got an OBD0 ECU you have an LED on the ECU which blinks out the codes, or you will be needing to fix your MIL ( globe )

SiR JDM
03-11-2004, 09:08 AM
I have a JDM SIR b16aII .. so whichever ecu that uses?
Im not too sure anymore after I read some whack shit on the net bout SIR ecus

How hard would it be to fix my MIL (globe) Ecu man?
I have a globe out around the 120 mark on my cluster.. not like i ever need to see that speed in the dark :P but it just annoys me that lil dark patch.
Is it hard to replace the globes? are the globes expensive?

ECU-MAN
03-11-2004, 09:38 PM
not really, once you got the cluster out, you just pull the globes out from the back PCB. when you 1st turn on the IGN to the II position the MIL shoudl come on for 6 sec or so then go out. depending on your ecu ( take a photo of the connectors ) you need to ensure the MIL wire goes to the globe. it may not be wired or not have a globe in the cluster. post a photo and we go from there :)

Guys I checked the ECU on the girlfriends EK4 a few mins ago but it was not the CEL that did the flashing.... it was the ABS!

Is this the same?

Also I got 61 16 and 18 :( I'm wondering what the 18 is for.

Ok so I got O2 sensor and Injector codes.... what would you recommend be the first things to do short of replacing the 02 sensor, and getting the injectors cleaned and checked?

Just unplug and check connectors are clean and reconnect?

ECU-MAN
10-03-2005, 07:53 PM
PGMFI and ABS fault codes are different.
how sure are you about code 16 ???
anyway code 18=
High Presure system
so thinngs that could be at fault
-Accumulator gas leakage
-changed relife valve set pressure
-rear outlet solenoid vale late to close
-changed pressure switch set pressure

code 61 fail safe relay

posible cause
-fail safe relay stuck on
-short to power in the solenoid drive circuits between the fail safe relay and ABS control unit
- faulty relay drive transistor ( in ABS ecu )
-short to power in the relay drive circuit between the fail safe relay and ABS ecu ECU

you need to test the output of your O2 sensor, to do this properly you need some kind of waveform viewer. or other wise get an O2 LED tester from Jaycar Electronics. see how responsive the O2 sensor is.

what fault code did you get for the injectors.

SPEEDCORE
10-03-2005, 08:35 PM
Ok I'm getting confused now..... so if the ABS light is the one that does the flashing instead of the CEL, it is a seperate set of codes to the ones listed on page one? I may have been reading the codes inncorrectly if so.

Anyway, with the fail safe relay, what specifically does it do?

We have been experiencing some difficulty starting the car in the last month. What's has been happening is that we put the key in turn to ACC then to ON where I always wait for the fuel pump to prime itself (the hummmmm then click sound), then once it clicks I turn the key to START but there is nothing, no clicking, no tell tale signs of the starter being screwed (it is about 7 months old) and the battery is fully charged about 1 month old. I then have to take the key all the way back to OFF then try again.

It doesn't happen all the time however.

Thoughts.... we can start a new thread to save clogging this thread up with these specific probs.

ECU-MAN
10-03-2005, 09:11 PM
yes ABS codes are different to PGMFI codes. there seperate systems.

the fail safe relays remove ground from the ABS modulator solenoids when activated. the ecu does this to revert back to normal braking due to some king of ABS failure.

its not fun driving a car that vents high pressure brake fluid to the master cylinder

also sounds like your main PGMFI relay needs some TLC

Bludger
11-03-2005, 01:14 AM

the del sol doesn has two blue plugs with one having 2wries(brown/black) and the other having 3wires.

so where do i plug the papaer clip in/??

ECU-MAN
13-03-2005, 08:05 PM
two wire connector
dont touch the 3 wire connector, you could damage the ECU by shorting that one

z3lda
13-03-2005, 09:18 PM
the connector with black/brown wire? isnt that ground wire or something?

ECU-MAN
14-03-2005, 10:38 PM
does it have a blue connector, is it located on the LHF kick pannel ?

z3lda
14-03-2005, 11:11 PM
yea, behind the carpet is the ecu then theres a green double plug unit.
in it has two little blue plug units
first blue unit has 2 wires brown/black
second blue unit has 3 wires which u told me not to touch

ECU-MAN
14-03-2005, 11:12 PM
yep then the two pin connector is the one you want

Hey guy was wondering just did the test and there were two lights flashing, the abs light and the engine light. do you know what is wrong when the asb light flashes? and also which is the oxegen sensor #1? because thats the only problem it indicates with the engine light. thanks

ECU-MAN
22-03-2005, 05:41 PM
audm Hondas only have 1 o2 sensor, unless you got a 88-91 prelude, or a V6.
ABS could be anything, how many flashes did you get for tyhe ABS

Blk-Em1
22-03-2005, 10:04 PM
I got a few codes for the abs they were like 18, and a few other numbers in the 60s and 70s
and also which 02 sensor are you talking about? the exhaust or the air intake sensor?

ECU-MAN
23-03-2005, 09:06 PM
6 ECT - water temperature sensor
12 EGR - exhaust gas recirculation lift valve
20 Electrical load detector
22 VTEC pressure valve


code 6, coz your sensor could be faulty

code 12, coz you put a H22 in your Accord, but did you also install the EGR solenoid ??

code 20, coz Accords CD5 doesnt have ELD unit in the under dash fues box

code 22, I dont thing your engine has a Vtec pressure switch, if it does then make sure its wired up.

just remember that the ecu you are using is looking for these sensors that are not connected or do not exist in your car. best way around this would be to can the P13 and go for a P30 and a nice tune on a dyno :)

23-03-2005, 09:10 PM

dude there is only 1 type of O2 sensor, always found on the exhaust side of the car. the intake as a few other sensors, like MAP, IAT, TPS.

also with your code 18 read post 18 in this thread
you need to be more spacific with your 60's and 70's codes if you want to know more about them

I did this paperclip trick, and I got no flashes, which I figured was a good thing. I then unplugged my O2 sensor to make sure I was doing it right.

With the O2 sensor unpluggedm I still didn't get it to throw any error codes??? Shouldn't it throw an error code?

ECU-MAN
11-04-2005, 09:13 PM
depends, if your got a one wire O2 sensor you will need to drive your car for a while for it to come on, if you have a 4 wire o2 sensor you should get a code straight away, code 41, o2 heater.

if you had no codes, its alll good, as long as the light stayed on.

Its a single wire O2 sensor. Nah the light didn't even come on. It comes on when I start the car, but that's it! Hmmmmm, is my car working as it should be.

Did the test this morning. Got warning code 15 - "Ignition output signal".

Not sure what this means and whether or not it's something I should be worried about.

I've found the troubleshooting procedure in the workshop manual, but it doesn't really explain what the error reported means.

EDIT: Well, I reset the ECU and it seems to have disappeared. So that's good.... I think. :p

when i turn car off the light just goes away

do i need to wait for the light to come on? or turn the car off and test the paper clip?

If it came on once, then do th test and check the code. You will have to reset the ECU to get rid of the code :)

ECU-MAN
08-08-2005, 09:41 PM
its located on the Auto transmission.
you will find 4 solenoids on the outside, front of the tranny

AT Lockup A & B

the PGMFI ecu locks up the torque converter at certain RPMs and speed using these two solenoids.

yes its the same

long flashes indicate tens
short flashes indicate units

ELD exists in the bottom of the main under hood fuse box.Its a current transformer that informs the ecu of the total elec load being drawn by the car.
I dont have one in my crx,so i didnt hook it up to the ecu,& i still get code 20 all the time but CEL does not stay on.
ECU-MAN reckons no adverse effects from this set up,& i dont seem to be having any,but only done 90kms so far.....

Is this a stock VTiR with stock ecu?

Usually a blue 2 pin plug clipped into a green holder with another 3,4 or 5 pin plug next to it.Usually directly below the passenger air vent.

If your really desperate just cut the SCS wire coming out of ecu

C7 on OBD2a(plugs on ecu seperated by a space)
A10 on OBD2b(plugs all side by side)

extend it to a switch & run a ground wire to other pole of switch,& switch on instead of having to short a connector.

SCS is usually a brown wire(sometimes with a stripe) trace it from ecu to find the connector.

Micko
04-10-2006, 08:37 AM
yes it is Stock ECU/Stock Car CRXer, thank you for the information... i know what plug your talking about its just not on the left side of the passenger foot wall so i will check near the centre console.. i shall have a look later today and get back to you,.

hey guyz, was tryng to do the ecu test yesterday but had no luck in finding the green holder with 2 blue plugs, all i found was 2 blue plugs hanging loose but didnt have the brown and green wire, but instead one plug has 2 wires black and brown and the other had 3wires light blue, brown and pink. would the blue plug with black and brown be the one im looking for? if it is..
just wondering why would it be hangin loose and could i still use it to perform the ecu test, or are my plugs just located in a completely different location,
thanx

Before u reset the ecu,make sure your counting them right.

Note any long blinks compared to short blinks, & the length of time between blink sequences,& report back.

To reset, turn ign key off,then pull out 7.5A fuse(i think) in engine bay fuse box.Same fuse as backs up the stereo & clock so dont forget radio code,etc.

whtteg
10-10-2006, 06:30 PM
its a definite 1 then 5 slow and 2 fast blinks ive tried searching everywhere to find code 52 (it may even be an old fault that has never been cleared by previous owner.)
if i do clear the ecu and fault is still there will it reappear so i can have it fixed?

Just check em again in any case,when ecu starts spitting erratic codes like this,usually means a prob with the ecu itself.Are u sure its the check engine light your reading?

Then reset ecu,take it for 2 seperate drives,ign key off between drives & see if any codes come back.

whtteg
10-10-2006, 06:45 PM
lol it certainly is the engine check light. i know code 1 is o2 and ive checked it 3 times and same codes each time and they just keep repeating themselves very strange.
so now i'l try resetting ecu and see if it comes back i'll keep you posted as to how it goes

No offence intended,seen cases where the CEL not flashing but ABS light is so they think that its an engine code.Cant remember the ABS codes but thought there might be a 52 for ABS & thats what u read by mistake.

Codes will just keep repeating everytime u check until reset

10-10-2006, 07:55 PM
Sorry,i didnt mention to pull the reset fuse for 10secs or more to let any charge bleed off the ecu so it wont hold the codes,I assume u know that anyway.

if its still repeating,start looking at the ecu.
Try swapping in a known good ecu if u can borrow one off someone & see what codes are still left

You need an OBD1 ecu,from something like a '92 - '96 model.

'92 - '95 model

If your goin to buy one,get the ecu specific to your car.

Also get it diagnosed professionally before handing over any cash.

well that may take a few weeks as i work 6+ days a wk while my manager is on hols, the engine light only comes on when its cold but after restarting the car when after it turns on it doesnt come on again until the cars cold again. will it hurt the car if i continue driving it till i have some time off?
will 1 from any b16a2 do?

CRXer
10-10-2006, 09:16 PM
Sorry,I meant an ecu specific to your engine,ie OBD1 AUDM? B16A,but its gonna be hard to find anything other than a crx ecu,no such thing as an aussie b16a OBD1 civic.

Wait for some cleverer types to come on & see if u can keep driving it,but if its spitting codes that dont exist,then who knows the extent to which it is working correctly.

Just take it down the nearest Honda dealer,they will most likely have a workin ecu on hand & can quickly do a swap to see what the prob really is before buying ecu's.

Try posting a wanted to borrow,gotta be some OBD1 ecu's cruising nearby somewhere.

what cars did have the b16a2?

CRXer
10-10-2006, 10:05 PM
Only yours for AUDM OBD1.

U could prob run a JDM ecu,but its not optimised for aussie fuel & compression ratios.Maybe one of the tuner boyz on here could correct me if it will still run your motor ok.
Aftermarket ecu is the other option,but u really got proper diagnosis before troubling yourself with all this.

JDM ECU will run the AUDM B16A2,

in stock form you will have a ELD problem which you could ignore

code 52 could be a result of a interal fault in the ECU. usually if you get a weird code that is not in the list, you have ECU issues.

if you can try another ECU.

CRXer
24-08-2007, 10:05 PM
Your ecu is telling u it has no fault codes to report,everything is fine.

If it continually blinks once at u with a short pause between each blink,that is an O2 fault,but one short blink is situation normal.

So are u gettin a CEL while driving?

Ignore code 20,u do not have an ELD in your car & has nothing to do with code 36 & will not cause a CEL

If u are gettin a CEL while driving,maybe u have to feed a dummy load to the trac cont inputs &/or outputs.PM ECUMAN he knows all this shit.

To reset(i assume your talking about the EK civic in your av),

Pull the 7.5Amp fuse out in your engine bay main fusebox for 10 seconds then replace(make sure ignition key is turned off before u do this).
If theres more than one 7.5Amp fuse,just pull all the 7.5's out.The one your after though should be marked clock/stereo/ecu(not the 15A ecu fuse) or something like that.

Then start your car & let it sit & idle for about 5-10mins,then go for a drive & see if the code comes back.

took the fuse out to reset the ecu but error still shows up when i do the ecu check

before i go buy another map sensor is there a way to check if it is the map sensor that is faulty?

i had the same problem.. just replace your map sensor it will disappear.

you could try going to Good Performance. they'll give you 3months warranty if the engine light comes up again. I paid 50 for parts, diagnosis, testing, and install.

Hi, I have a Honda Civic 1.5L GL 92 Engine D15B7, for the life of me I cannot find the two wire connector. Looking at the pictures at the beginning of this post, I can see the brown and grey connectors but no green covers and no blue connectors? Are they in a different place on this car?

Hi ECU-MAN, I have moved the passenger carpet out the way, and unbolted the ECU from its brackets and nothing absolutely no sign of the connector or the green housing? Could it be possible my car has no service connector?

helo ECU-MAN, I'm driving a 1993 honda civic eg9 ferio, my cheklight is always on when I am driving and I have used your checklist and this is what i get, 1.(O2A-oxygen sensor #1)
3. (MAP-manifold absolute pressure sensor) 41.(Primary oxygen sensor heater)
43.(Fuel supply system)(PS 3. and 5. are they the same? as both are stated manifold absolute pressure sensor)
But before I had done these checks on the ECU, I had visited my mech and after checking it, he advise he advised me that I need to change a HondataS300. Please advise.

Is code 3 and 5 supposed to be the same? or is it just a typo?

hey there, thanks for the great detailed write-up. i'm new to hondas so just wanted to ask a couple Q's that i couldn't find answered in the other pages.
after pulling the carpet back i instantly found 2 connectors hanging there. one with 3 connectors and one with 2 connectors.

on my 95 EG5 civic the 2 connector wires are black and brown? is this correct?
and is it supposed to be re-connected back to something once you reset the ecu, or just leave it dangling like i found it?

thanks :)

I'm getting this also in my eg5 B18C2...tried resetting ecu, topping up oil...still occurs so im guessing theres a problem with the switch? Or i'm losing pressure elsewhere? any ideas?

Today I tried the test The engine light switches off initially and comes back on and stays on does that mean its 10? or there is no fault?

ECU-MAN

I just tried out your DIY and i got 61 but it was my ABS light flashing and Engine light just stayed on.
primary Oxygen sensor
i have problems starting my car up in the morning or leave the car sitting for over 8 hrs, it starts up like the battery is dieing and then turns over and starts.
tested the battery and its fine, would this sensor cause a difficult start?

If I'm interpreting correctly, you have a code 1 and code 10, see the first page for what they mean.

I just got a new cluster, and the CEL isn't lighting up (even with the key on II) I used to have the Non-Tacho cluster before that doesn't have a CEL either so i'm not sure if there's something wrong with my ECU or something.

PS: I already swapped the bulbs behind the cluster and the CEL is still not working.

i may be wrong (someone to 100% confirm this??) but for some EK owners the plugs are not on the left side of the passenger footwell but on the right side.

for my brothers gf car thats where it was located, and there was no big green plug, it was blue. you'll see the 2 blue connectors, one that 3 wires, the other has 2 wires (brown and black).

Cars not starting after a clutch change and I'm getting code 61 and 81 on the ABS light, anyone know what those codes mean and could it be the reason for the car not starting?

Never mind, found the codes in the manual and erased the codes.
