4AGE ECU codes

[RolandGTV85]

Hey people.

Apparently when my 4AGE ecu was hooked up to diagnostics it kept coming up with code "5" which is not a toyota diagnostic code........even after being reset....

Anyone know what this code is? My mechanic seems to think it is a modified ECU.......

any thoughts?

I'm also up for a new radiator.......ughhhhhh :fap:

what was the flashing sequence

Just wondering if anyone knows anything about this.

Moved to the right section... a Technical question should be asked in the Technical Question area

<div class='quotetop'>QUOTE (gunbz-r @ Sep 10 2008, 07:01 AM) </div>Absolutly Positive it was 5........If anyone knows and can tell that would be great. I honestly dont know anything about ECU's so I have no idea haha

did you see it flash? it would flash 5 times, but in what sequence, i seriously doubt, that if someone modified it, they would go to the extent of trying to modify the codes, and you can't retune factory toyota ecu's

I will just about bet my balls, that it is 23 or 32, either it flashed twice paused then flashed 3 times, or vice versa

Do you have a pic of this so called modified ecu, or atleast a part number
