DESCRIPTION

The forward recognition camera receives vehicle information from the hybrid vehicle control ECU assembly via the CAN communication line.

When the forward recognition camera is unable to determine the vehicle information from the vehicle information sent from the hybrid vehicle control ECU assembly, the forward recognition camera outputs U030051.

When the vehicle information sent from the hybrid vehicle control ECU assembly does not match the vehicle information stored by the forward recognition camera, the forward recognition camera outputs U030057.

DTC No.

U030051

Internal Control Module Software Incompatibility Not Programmed

The forward recognition camera cannot confirm the vehicle information from the hybrid vehicle control ECU assembly.
  • Hybrid control system
  • Forward recognition camera
  • Hybrid vehicle control ECU assembly

U030057

Internal Control Module Software Incompatibility Invalid/Incompatible Software Component

The vehicle information from the hybrid vehicle control ECU assembly and that stored in the forward recognition camera do not match.
  • Hybrid control system
  • Forward recognition camera
  • Hybrid vehicle control ECU assembly

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.
  • When the forward recognition camera is replaced with a new one or the windshield glass is replaced or removed/installed, make sure to read Before Starting Adjustment, then perform optical axis alignment for the forward recognition camera and clear the vehicle control history for each system.

    HINT:

    Forward recognition camera axis alignment can be performed by using either One Time Recognition, Sequential Recognition or Driving Adjustment.

HV/EV Equipped Information

Vehicle information (engine) stored by forward recognition camera

Non-HV/EV or HV/EV

Non-HV/EV: Gasoline Model

HV/EV: HV Model

If a display different from vehicle specification is output, a forward recognition camera that was used with a different vehicle was installed, or the forward recognition camera may be malfunctioning.

HV/EV Equipped Information

HINT:

  • When the specification stored by the forward recognition camera and the vehicle specification do not match, there is a malfunction in the specification information stored by the forward recognition camera. Therefore, replace the forward recognition camera.
  • When the specification stored by the forward recognition camera and the vehicle specification match, an hybrid vehicle control ECU assembly with different specifications may be installed. Therefore, replace the hybrid vehicle control ECU assembly.
