Data Trouble Code Retrieval for Alpha Engines

With the increasing rate of people wanting to know the process of carrying out their own "code checking" precoedures, I have developed an article which will tell you step by step, what to do when trying to eliminate problems, using the on board diagnostic system.

Data Link connectors:

Accent 95-99 - above the right most switch panel
Accent 00-Current - below the lower dash shroud
Getz - below the lower dash shroud

Data Link connector configuration:

(IMG:http://img124.exs.cx/img124/2267/DLC1.jpg)

Data Trouble Code Retrieval (using M alfunction I ndicator L amp):

1. Ignition switch on (do not start)
2. Ground the L-wire (bridge No. 15 pin and No. 4 pin) in the Data Link Connector for 2.5-7 seconds.
3. If there is no fault, code "4444" will be indicated.
4. Each code is repeated infinitely until the next step is ordered.
5. To order the next code to apper, you are required to ground the L-wire again for 2.5-7seconds, after that the next code follows.
The last output consists of the code for end of "code output" which is "3333". After grounding the L-wire again for 2.5-7 seconds, the diagnostic mode is left.

Remember: There will always be four digits in each code output.

Code List is as follows:

Remember: These are only guidelines to aid you in your diagnosis. They will not provide a definite answer as to what component you should replace, but moreso, identify in which area you are experiencing problems.
I will personally hold no responsibility for any failures that may occur to user carelessness!

Actuation Test

There is also an actuation test which can be carried out in order for you to determine whether your actuators are operating correctly.

Actuator Control Sequence Procedure

1. The L-wire (No. 15 pin) in the data link connector has to be grounded before turning the ignition key on (DO NOT START).
2. Turn the ignition key on (DO NOT START) and then disconnect the grounded wire from pin No. 15, then the actuator activation sequence will begin, starting from the fuel pump relay.

NOTE: Each actuator will be stopped after activating 6 times

3. Once the actuator has activated 6 times, you will then be required to ground the No. 15 pin again to follow on to the next actuator in the sequence, which will be listed below:
Test Item__________________Fault Code
1. Evap can. purge valve solenoid_______________1322
2. ISC vAlve solenoid_________________________1321
3. No. 2 injector _____________________________1315
4. No. 3 injector _____________________________1314
5. No. 4 injector _____________________________1313
6. No. 1 injector _____________________________1312

4. If the actuator responds normally, code "4444" (No Fault Code) will be indicated by the MIL.
If there is any faults, the relevant trouble code will be displayed via the MIL.

Can you use this method to troubleshoot the air bag circuit?

I tried this procedure on my '98 and got no response from the CEL. :(
Car is a "L'' model, Canada, 1.5L SOHC, manual trans.

So, either the procedure isn't valid, or my car doesn't have this feature, maybe because it's manual transmission.

I guess I need a code reader after all. :|

I hope my ECU DLC interface isn't fried - Mr. Hundi.

DO NOT ATTEMPT AT ANY TIME TO EXTRACT CODES FOR, OR ATTEMPT TO REPAIR YOUR SELF, ANY AIRBAG UNIT!!!!!!!!!

pUT A DOLLAR SIGN ON YOUR HEAD AND YOU WILL SEE THAT IT WILL ALWAYS END UP MORE THAN THE BILL YOU WILL GET FROM HYUNDAI!!!!

Hi,i have a british 2000 accent 1.3 12v which has got the OBD11 16 pin socket,could you tell me if this procedure works on mine thanks.

I have a 1999 Accent (Canada). Could not locate the DLC connector? Any idea where it is?

^I have the same question.

its right above the dimmer switch,

on ur left u know that lil square deep cubby hole on dash by drivers door?
its thyere inner upper lip of cubby hole

Hi guys,
We have a 2000 Hyundai Accent (UK model) and I have found the data link connector below the lower dash shroud.

I tried the above method but there doesn't appear to actually be a connection in pin no. 15 (no. 4 is there)

Is this because it's a manual as someone posted above?

Any ideas what else I might try?

I also foolishly grounded pin 16 (marked B* above) - and it gave off a tiny little spark. There's no chance I've shorted anything is there? :?

Thanks.

I think the only OBDII reader which will `plug & play` directly into the data port is Hyundai`s own Hi-Scan Pro device.
This is also used by techs at the Dealerships to upload software revision packages issued by Hyundai.

Despite the fact that Hyundai electronic engine management consists of commercially available Bosch/Siemans components, the programming is via Hyundai`s own coding........& no-one has managed to re-write tuning modifications directly (as can be done with VAG Group cars).
The nearest tuners have got so far, is to mount an additional EPROM into the ECU & program that!.

If your car is running normally, I doubt that your accidental short has done any damage.

Cheers,
Nick.

so how do i no what code is being displayed?
will the mil flash will it
ie code 1234: one flash, solid, 2 flashes, solid, 3 flashes, solid, 4 flashes?
is that what will happen?

Does the MIL flash the codes? Does anyone know if this works on the original shape Coupe's?

Any help greatly appreciated.

so what to do if this procedure doesnt give codes :|

99 accent from canada

the light just stays solid :S

First of all, this is an excellent guide for retrieving the diagnostic information.

I've located some problems and fixed them using this guide. There are however one thing that is bugging me about my ECU/ECM's diagnostics.

When I'm testing the actuators I get error codes for all of them. If this were correct then it would mean that none of my injectors and so forth is functional. But this doesn't seem to be the case since I'm still able to start my car.

I assume that when the ECU is entering the actuator diagnostic unit, one should actually hear the injectors operating if the ECU/ECM is testing them, isn't this the case?

When doing the normal diagnostic routine, there are no error codes given that my ECU/ECM is faulty.

Any ideas why this scenario is happening?

Hi All
I get the same readings as Jakkals but my car is not working. Any ideas out there??

I'm probably being really stupid asking this, not for the first time, but I'll ask anyway. The codes you all speak of, (1234, 4444, etc.), is there a special device which I need to buy to read them, or are they indicated by a light flashing somewhere? :whistling: :whistling: :whistling:

The code is indicated by the engine check light flashing. I believe it will flash for example 5 times for "5" followed by a pause before the next digit ;)

hi there.
every now and then the 'check engine' light comes on on my 1995 1.3i accent. i have followed the instructions and brought up the flashing MIL to get the fault code. the problem is if i am reading the flashes correctly it doesn’t correspond to any of the fault codes i have (those on autodata and this site). i am getting 1 long flash followed by 4 groups of 2 short flashes. there are only 3 codes that start with '1' but the rest of the flashes dont follow for the rest of the code. am i reading this correctly? another point is, do i need to bridge the data link connector each time to get each part of the fault code, so i could read the flashing i get as '18' which then doesn't correspond with any fault code! thank you.

Hi. I have a 2001 Accent 1.3 UK model. The engine check light has been on and off for the last two years, now it's just on! I was going to buy a ODB2 reader to diagnose the problem and clear the check light, but from what VALKYRIE YB70 says, it sounds like an off-the-shelf ODB2 reader will not work. Is this the case?

Also, can anyone tell me exactly where the DLC is on a Right-Hand Drive 2001 Accent?

Thanks very much.
