Title: PRE-COLLISION: PRE-COLLISION SYSTEM (for HV Model): U030057; Internal Control Module Software Incompatibility Invalid / Incompatible Software Component; 2020 MY Corolla Corolla HV [01/2019 - 04/2020]

DTC

U030057

Internal Control Module Software Incompatibility Invalid / Incompatible Software Component

DESCRIPTION

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

If the vehicle information stored in the forward recognition camera differs from that sent from the hybrid vehicle control ECU, the forward recognition camera stores this DTC.

DTC No.

Internal Control Module Software Incompatibility Invalid / Incompatible Software Component

When the power switch is on (IG) for 3 seconds or more, the vehicle information sent from the hybrid vehicle control ECU does not match that stored in the forward recognition camera for 1 second or more.

  • Hybrid control system
  • Forward recognition camera
  • Hybrid vehicle control ECU

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.

HINT:

  • If the vehicle information stored in the forward recognition camera is different than the actual vehicle specifications, the vehicle information stored in the forward recognition camera may be incorrect. Check for DTCs and replace the forward recognition camera if necessary.
  • If the vehicle information stored in the forward recognition camera matches the actual vehicle specifications, the installed hybrid vehicle control ECU is incompatible. Replace the hybrid vehicle control ECU with a correct one.
