This item is a complete plug and play ECU for you 2004-2006 Lexus LS430. This Lexus ECU includes on-board repairs, board cleaning, and damaged or compromised component replacement. We also update your ECU’s software to the latest revision. The software we use comes directly from Toyota and is the same a dealership would use to update your ECU. Some of these ECU’s need updates for rough shifting.

We also repair the physical on-board problems that cause the rough downshifting problems and clunking when downshifting from 3rd gear to 2nd gear and 2nd gear to 1st gear.

There is an easy process to sync this new ECU with your vehicle immobilizer so it will start. It involves jumping two pins at the OBD port and waiting 30 minutes. Once this process is complete your car will start with the new ECU.

We program your VIN number into this ECU. You will have a P0630 if this is not done.

This service will not resolve check engine error codes. You would need to determine what the codes are and then resolve those codes.
