Lexus UX Computer Diagnostics
- UX shares diagnostic architecture with Toyota C-HR — Techstream reads all ECUs; workshops familiar with C-HR often handle UX well
- UX check engine light: common causes — mass air flow sensor, O2 sensor, spark plugs (on M20A-FKS petrol) — scan before replacing
- UX ADAS recalibration: Toyota Safety Sense cameras on UX — if windscreen or camera replaced, system must be recalibrated
- UX 250h hybrid: Techstream shows HV battery cell balance and 12V battery state of health — request this data at 60,000 km service
