DIY - Steering ECU replacement
I have searched but come up with nothing--is there at all a DIY to replacing the ECU?
- Do I need to remove the car battery? If not, do i need to ensure it is disconnected before pulling out the steering ECU? Can I just pop out o fuse so that I do not lose any error codes in the main ECU and the presets for radio, seats, etc?
thanks

i thought the calibration was only required for a new ECU and recommended for brand new ones. Mine came from another IS--forgot to mention that.
who besides dealers has this thing? does a toyota dealer have techstream or only lexus?

you can drive with the ecu calibrated for the other car.. its just not calibrated for YOUR car. That in mind, i dont think your steering would be any more precise by just dropping it in, so i can only encourage you to get it calibrated, by anyone with a tech stream that is qualified to do it.

Can someone confirm where the power steering ECU is located? My mechanic told me it was under the cover below and to the left of the steering wheel, but in this thread someone said it was located under the battery. Google has been no help at all.
