U030057

Internal Control Module Software Incompatibility Invalid / Incompatible Software Component

When the ignition switch is ON for 3 seconds or more, the vehicle information sent from the ECM does not match that stored in the forward recognition camera for 1 second or more.

  • 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 the forward recognition camera 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, forward recognition camera adjustment must be performed.

    HINT:

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