Ok, so after i blew a main fuse, i replaced it, car runs fine, no problems. I can log in EvoScan so i figured the ECU is working and is ok. I go to try to Re-Flash the ECU and it wont work. It sends some sequences, then it stops and tells me it wont work.
When i blew the main fuse, the re-flash cable was not plugged into the ECU/ however the regular OBD-2 connection was, so i doubt i fried the cable because everything reports back in EvoScan with no problems. did i break the ECU? is there a relay or fuse somewhere that i may have blown before the ECU? i checked all the fuses were ok. Any ideas?!?

Here is what happens:

sending init sequence 1 (0001)

sending init sequence 1 (0003)

sending init sequence 1 (FFFF)

"no response to any known code"

Since it works in EvoScan, im thinking i shorted out the cable or something? If i shorted the ECU the car wouldnt run im pretty sure right?

 

Any ideas guys? its important i figure out whether i need a new ECU or just a new Re-Flash tactrix cable becuase im still in the process of tuning

 

Does your cig lighter still work mitsu?

 

Yeah it does, why would that matter j/w! Well actually let me check, becuase i also had my garman charger in the cig lighter at the time, and now that wont work, i cant find a way to open it up to see if the fuse blew in the charger unit.

EDIT:: However i can put my power inverter in the cig lighter and it powers up ok, so im guessing the cig lighter does still work

 

I asked that because most cars will have the fuse for the cigarette lighter also be the fuse for the obd port. I was curious if we could still log with a blown fuse but not actually extract or write information. It was a shot in the dark

 

I see what your sayin, damn i checked all the fuses under the hood, and under the dash, there all fine :-(

 

Have any friends close by you could try to read there ecus?

 

No damn.. i have a galant, but do they have a reflash port?

 

Depends on the year but it should. Did you say you could not write or read? You coul try to just read your galant maybe

 

Yeah ECUFlash wont let me write to ECU, or even read the ECU. Ok, ill try to read the galant when i get home from work today. Its just so weird becuase when the fuse poped, the OBD-2 connection was still connected but the re-flash cable was not, however now the re-flash cable WONT work, but the OBD-2 cable does because EvoScan works fine

 

Honestly I am kind of leaning towards something in your ecu fried blocking your ability to read/write but lets see what happens with the galant.

 

I hope not Ill keep you updated with the galant later tonite, how much do you think a new ECU would cost?

EDIT:: just got a quote from LKQ 150 my cost (work at kia in the parts dept) so i guess not too bad. Ill run the test on the galant tonite

 

Thats not too bad then, just a little more than another cable would be anyways

 

Alright bro, so i tried to read from the galant ECU and got the same exact code. What do you think? should i try a cable first? the OBD-2 connection smeels really bad, like a bad battery, its horrible Is there anyway of testing my ecu to confirm its a bad cable?

EDIT:: Opened up my tactrix cable by removing the exterior plastic. Once i opened it up i saw the things on the circuit board that just plain fried out, big black spot with a line going through it on one side, and on the other, one peice of metal actually melted. Ill post pics in the morning!

 

Well that sounds confirmed to me man. New cable it is
