Internal Control Module Software Incompatibility Not Programmed

DTC

U030057

DESCRIPTION

for HV Model:

  • The forward recognition camera receives vehicle information (Conv/HV) from the hybrid vehicle control ECU via the CAN communication line.
  • When the forward recognition camera is unable to determine the vehicle information (Conv/HV) from the vehicle information (Conv/HV) sent from the hybrid vehicle control ECU, the forward recognition camera outputs U030051.
  • When the vehicle information (Conv/HV) sent from the hybrid vehicle control ECU does not match the vehicle information stored by the forward recognition camera, the forward recognition camera outputs U030057.

for Gasoline Model:

  • The forward recognition camera receives vehicle information (Conv/HV) from the ECM via the CAN communication line.
  • When the forward recognition camera is unable to determine the vehicle information (Conv/HV) from the vehicle information (Conv/HV) sent from the ECM, the forward recognition camera outputs U030051.
  • When the vehicle information (Conv/HV) sent from the ECM does not match the vehicle information stored by the forward recognition camera, the forward recognition camera outputs U030057.

  • Hybrid control system
  • Forward recognition camera

for Gasoline Model:

  • SFI system
  • Forward recognition camera

U030057

Internal Control Module Software Incompatibility Invalid / Incompatible Software Component

for HV Model:

  • Once 3 seconds elapse after turning the ignition switch to ON, the vehicle information (Conv/HV) sent from the hybrid vehicle control ECU does not match the vehicle information stored by the forward recognition camera for approximately 1 second or more

for Gasoline Model:

  • Once 3 seconds elapse after turning the ignition switch to ON, the vehicle information (Conv/HV) sent from the ECM does not match the vehicle information stored by the forward recognition camera for approximately 1 second or more

for HV Model:

  • Hybrid control system
  • Forward recognition camera

for Gasoline Model:

  • SFI system
  • Forward recognition camera

CAUTION / NOTICE / HINT

NOTICE:

  • When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
  • If the forward recognition camera has been replaced with a new one, be sure to perform forward recognition camera adjustment.

    HINT:

    Forward recognition camera adjustment can be performed by using either "One Time Recognition" or "Sequential Recognition".

    One Time Recognition:

  • for HV Model:

    Before replacing the hybrid vehicle control ECU, refer to smart key system (for Start Function) Precaution.

  • for Gasoline Model:

    Before replacing the ECM, refer to smart key system (for Start Function) Precaution.
