Code No.U1195: Coding not completed


caution
  • If diagnosis code No. U1195 is set, diagnose the CAN bus lines.
  • When replacing the ECU, always check that 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 registered, the engine cannot be started. Register the encrypted code as described in Immobilizer System - How to Register Key ID .)

DIAGNOSTIC FUNCTION


If the vehicle information data is not registered to the ETACS-ECU, the heater controller assembly (A/C-ECU) sets diagnosis code No. U1195.
