Either. Best one is Learning View though as it'll read the error codes too. The others just allow you to reset the ECU thus clearing the codes.

You could try Ecuflash first. Sometimes the ECU definition are not complete but usually they are decent on OBD code list.

Romraider usually have better ECU definition for Subaru and you would be able to see more stuff.

Learningview are better for seeing the trouble code. It can reset the code but not disable it.

Neither can ROMRaider unless you have a Tactrix cable / OP2 - most of the cheap eBay OBDII cables will only let you read and not write the ECU.

RomRaider and Learning View are free BTW so no reason not to get them.

as jstawgn says learning view only reads. To save rom you will need ecuflash and tractrix, this also has ability to edit rom and permanently remove the codes. you could download romraider but you will still need ecuflash to retrieve original rom and flash modified version back. ive has issues using op2 drivers with romraider recently, works faultless with op1.3 for logging, but exploring paying options such as ecuedit instead.

im in the shire and have tractrix and have flashed my own car a few times. think 08 may be canbus havent tried one of them. do you have openport 2.0 cable already andy?

i got an example .hex map file off web to look at in ecuflash

i cant figure out how you disable a DTC code e.g. P2444

so opened it in romraider, simple to disable there. saved the file and reopned in ecuflash and the code is disabled

out of interest how do disable a code in Ecuflash!?

open the rom in ecuflash, once opened scroll down to the trouble code you want to disabled and click the check box. A windows will appear saying whether enabled/disabled. click the value then go to edit bar and use increase or decrease and that will change value. The description of item you have changed in rommetadata pane will turn pink to show that value has been altered.

Arise, oh zombie thread.

Bing/Google searches brought me to this thread whilst on my quest to figure out how to change state of DTC trouble codes with EcuFlash. I offer the following as a means of paying forward the benefit I received from the work of those who went before me.

open the rom in ecuflash, once opened scroll down to the trouble code you want to disabled and click the check box.

Like andycook and others, I also had trouble determining how use EcuFlash to change a DTC P-code from Enabled to Disabled. Like them, I resorted to using EcuFlash to read/flash the ECU, and RomRaider to edit the state of the DTC codes.

OpenECU & RomRaider sites have a LOT of helpful information, but speaking for myself, no clear directions about changing DTC codes in EcuFlash were uncovered.

While posts about the subject appeared in several forums, making it evident that others HAD changed state using EcuFlash, their skimpy descriptions left the impression that it was done with a radio button or a drop-down pick list, not from the DD menu. As a noob, I was certainly reluctant to dabble.

Euan's directions above were the best of the lot I encountered. I thank him for showing me how to move forward in EcuFlash.

But.

I believe Euan should have written "use INCREMENT or DECREMENT". This is because changes made with those menu choices are reversible.

In contrast, if I use Increase or Decrease in my instance of EcuFlash, "Enabled" will change to "Disabled" - but the changes made with these menu choices are NOT reversible. The state of the DTC can not be flipped/restored back to the original condition of "Enabled".
