DTC C1707: Implausible coding data: Notes
CAUTION:
- If there is any problem in the CAN bus lines, an incorrect DTC may be set. Prior to this diagnosis, diagnose the CAN bus lines .
- Whenever the ECU is replaced, ensure that the communication circuit is normal .
- When DTC C1707 is set in ACC/FCM-ECU, the DTC may also be set in ETACS-ECU. When the DTC is set in ETACS-ECU, perform the diagnosis of the DTC for ETACS-ECU first .
- 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 .)
- When the ACC/FCM-ECU is replaced, calibrate the radar (refer to ADAPTIVE CRUISE CONTROL SYSTEM COMPONENT CHECK ).
