Why did you replace the computer? What was the code?

Lets start from scratch. Hope you have the old computer

If you did not change it, then how did you get the message. There is no code for fuses for pcm.

Anyway, lets start with the codes? Give me the number and we go from here

No code came up all it said was can connect check fuse. So then we looked it up in a book and it says that to check the fuse and if the fuse are good then the ECU is Bad. So for the hell of it we try I another computer just to make sure the computer was good and it said the same thing can't connect check fuse. Let me ask u something I can't find a computer with all the same part numbers the one I found is for the same year lexus but the last 3 part numbers are different does that make any different if I put it in will it work?
