2004 Hyundai/OBD2 questions

[dyeager535]

Just a little upset, lost my post. :( Not of the mood to re-type the whole thing. Cables all the same for OBD2? Can buy from ebay the $6 USB/OBD2 cable? Software like any other, just has to support the vehicle make/model?

Need to be able to do this on the referenced car:

2.
Check PCM


(1)
Ignition "OFF"





(2)
Connect Scantool and Engine "ON "





(3)
Select simulation function on scantool.





(4)
Simulate voltage at terminal 2 of HO2S(B1/S2) sensor signal connector.






(5)
Is HO2S(B1/S2) signal value changed according to simulation voltage ?



YES







1)
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination,deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.









NO







1)
Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "Verification of Vehicle Repair" procedure.

Found these http://sourceforge.net/projects/scantool/ http://torque-lite-obd2-and-car.soft112.com/ but can't test them out until later today. I somewhat expect they don't have the functionality to do this though.

I doubt you'll find Bi Directional controls from a freeware PC software. Normally they are read codes and data...

[dyeager535]

Can you recommend any non-free software that is likely to do what I'd need? I suppose if it's versatile software, I could use it on all my friends and families cars at some point.

Doesn't seem like many Hyundai owners are into repairing their own vehicles, so not much out there I've found that is of much use. Probably because resale is about as much as the converter costs. lol

Seems to be lots of options out there for software, but as with everything, support, functionality, etc., looks like it varies vastly.

Scan XL Pro is good and can get GM enhanced PIDS for good tuning. Still not sure you can do Bi Directional controls through a PC? Well maybe EFI Live does?

I have an Actron 7000 that does the bi directionals

[dyeager535]

On the off-chance they rented them, I called autozone, they said they didn't rent anything that would do what I needed to do.

The dedicated tools seem to be pretty pricey, but if bi-directional can't be had via a PC, might not be many options.

Going to need to see what the O2 sensors are doing too, it is unfortunate that the bi-directional stuff isn't a standard. Scan XL appears to only have "generic" stuff for Hyundai, and I didn't see anything indicating it could do what I may need. EFI Live looks to be only GM and Dodge?

[EagleMark]

Scan XL Pro with enhanced GM PIDS is as good a PC software tuning tool as the EFI Live scan tool. If you needed something for TunerCat OBDII. But it's still not a automotive tech type scan tool.

A few years ago I bought a Auto Xray 7000 and it has done anything I needed it for including OBDI, OBDII, Ford etc... lots of diagnostic ends. Been a great tool. Out dated to newer expensive version 9xxx.

But they are still available like this one $245 new and no bids. (EDIT: Sorry that says slightly used!) I think new you can find them around $300+

Been a great tool and I don't know if it has all you need for a HYdyia, but we compared it to a Snap On Scan tool couple years ago on a 2009 Chevy truck and there were no shortcomings. Except it was about $1000 less...

[dyeager535]

Ugh. Probably costs more than the car is worth too lol.

So it says bi-directional. Looks like you just have to hope it does the test you need. :( Thats what I get for buying a non-US maker car apparently!

[EagleMark]

I guess the real question is why in the world do you own a Hyundai? :laugh:

[dyeager535]

Well, since you asked...lol

Had a pressing need for vehicle to get to work (as in have to get it by tomorrow) years back, and ended up getting a Kia because it was cheap and mileage was good. Got hit on the freeway seven months later, decided to try the Hyundai as there were things I didn't like about the Kia. Honestly didn't want to deal with car problems to get to work.

Now, say what you will, but $9000 new, 9 years, 121K, still pulling down 38-40MPG each tank. This is the first non-regular maintenance issue the car has had in that entire time.

Had never considered the repair aspect...I just figured OBD2 was OBD2. This is where I have to question how much time and effort I spend on this, vs. generating a car payment I can ill afford.

[EagleMark]

Heck that's not a bad investment for that many miles and years to work.

Back to initial problem can't you check the O2 voltages without scan tool controls? Is it a CEL PID issue?
