Toyota Yaris: Dynamic Radar Cruise Control System / Internal Control Module Software Incompatibility Not Programmed (U030051,U030057)

Toyota Yaris XP210 (2020-2026) Reapir and Service Manual / Engine & Hybrid System / Cruise Control / Dynamic Radar Cruise Control System / Internal Control Module Software Incompatibility Not Programmed (U030051,U030057)

DESCRIPTION

If the millimeter wave radar sensor assembly cannot confirm the vehicle information (powertrain type) sent from the ECM, the millimeter wave radar sensor assembly stores DTC U030051.
If the vehicle information (powertrain type) stored in the millimeter wave radar sensor assembly does not match the vehicle information sent from the ECM, the millimeter wave radar sensor assembly stores DTC U030057.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	DTC Output from
U030051	Internal Control Module Software Incompatibility Not Programmed	While the dynamic radar cruise control system is operating, the millimeter wave radar sensor assembly cannot confirm the vehicle information (powertrain type) sent from the ECM for approximately 3 seconds or more.	Pre-collision system	Radar Cruise2
U030057	Internal Control Module Software Incompatibility Invalid/Incompatible Software Component	While the dynamic radar cruise control system is operating, the vehicle information (powertrain type) stored in the millimeter wave radar sensor assembly does not match the vehicle information sent from the ECM for approximately 1 second or more.	Pre-collision system	Radar Cruise2

PROCEDURE

1.	GO TO PRE-COLLISION SYSTEM

HINT:

If DTC U030051 is output by the dynamic radar cruise control system, perform troubleshooting for the pre-collision system.
