Manufacturer summary

Original wording in English

TSB: Some 2023 model year RX 500h vehicles may exhibit a MIL ON condition with Diagnostic Trouble Code (DTC) P24517F ? Evaporative Emission System Switching Valve Actuator Stuck Off present. This DTC may erroneously be displayed when the fault is related to DTC P14502A ? Fuel Tank Pressure Sensor Signal Stuck in Range. The Engine Control Model (ECM) (SAE term: Powertrain Control Module/PCM) logic has been modified so DTC P24517F will not be erroneously detected. Follow the Repair Procedure in this bulletin to address these conditions.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
