Hi.

In attachment first eeprom from similar ECU IS250 MY 2006 93c56
Don`t forget to put synchronization bytes manualy from ID BOX 93c46 to this dump.
Solution with shotting contacts of DLC connector not works on this smart systems.

if it is a smart system it has a smart box, immo box and ecu

In case, if you swapping only motor ECU on this Toy/Lexus smart system, you need only rewrite synchronization bytes from ID BOX(immobox) or from 1-st eeprom from old ECU.
