When the ETACS-ECU is replaced, VIN writing and coding must be performed. When DTC No. B1760 "Coding not completed" or B1761 "VIN not programmed" is set in the ETACS-ECU, perform VIN writing and coding. Refer to the "M.U.T.-III Owner's manual" and perform coding.
When the ETACS-ECU of vehicles without KOS is replaced, the encrypted code of the ignition key needs to be registered to the ETACS-ECU. (If the encrypted code is not registered, the engine cannot be started. For the details of code registration procedure, refer to the ID registration procedure manual.)
