Toyota Yaris: 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 |
|---|---|---|---|---|
