DTC U0101: T/M CAN timeout: Notes
CAUTION:
- If DTC No. U0101 is set in the ETACS-ECU, always diagnose the CAN bus line.
- Before replacing the ECU, ensure that the power supply circuit, the ground 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 .)
