Toyota Camry (XV70): Internal Control Module Software Incompatibility Not Programmed (U030051,U030057)

Toyota Camry Repair Manual XV70 (2018-2024) / Engine, Hybrid System / Cruise Control / Front Camera System / Internal Control Module Software Incompatibility Not Programmed (U030051,U030057)

DESCRIPTION

The forward recognition camera receives vehicle information from the ECM via the CAN communication line.

When the forward recognition camera is unable to determine the vehicle information from the vehicle information sent from the ECM, the forward recognition camera outputs U030051.

When the vehicle information sent from the ECM does not match the vehicle information stored by the forward recognition camera, the forward recognition camera outputs U030057.

DTC No.

  • Forward recognition camera
  • ECM

U030057

Internal Control Module Software Incompatibility Invalid/Incompatible Software Component

The vehicle information from the ECM and that stored in the forward recognition camera do not match.
  • SFI system
  • Forward recognition camera
  • ECM

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.

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 ECM with different specifications may be installed. Therefore, replace the ECM.

Result

Proceed to

Specification stored by the forward recognition camera and vehicle specification do not match

A

Specification stored by the forward recognition camera and vehicle specification match
