the communication circuit is normal.

• 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 reg-
istered, the engine cannot be started. Regis-
ter the encrypted code as described in 
Immobilizer System 

− How to Register Key ID 

.)

power supply fuse, or odometer value is 80.5 km or 
more, if the communication with ETACS-ECU cannot 
be established for 2,500 ms or more, the electric tail-
gate control unit determines that a problem has 
occurred.
