; Programmed for other ECU4.1 Replace the transponders with new
4.2 Perform immobilizer programming
5. Re-programming is not performed
after clearing transponder code stored
in ECU that normally used system5. Immobilizer programming
Notice
1. Application of ex-programmed transponder into other ECUs.
; In this case, it can not be removed for the settled “lock bit” in transponder even though you perform immobilizer
problem normally. Moreover it is impossible to start engine, so replace the transponder with new and perform
immobilizer programming.
