Code No.U0151 SRS-ABG CAN timeout

CAUTION

• If the diagnosis code No. U0151 is set to the 

ETACS-ECU, always diagnose the CAN bus 
line.

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
