Code No.U1005 Corner/Back SNS.ECU CAN timeout


caution
  • If the diagnosis code No. U1005 is set, be sure to diagnose the CAN bus line.
  • Before replacing the ECU or combination meter, ensure that the power supply circuit, the earth circuit and the communication circuit are 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 .)
