Manufacturer summary

Original wording in English

TSB: Some 2004 ? 2009 model year Prius vehicles may exhibit a MIL ?ON? and brake warning lights (ABS/VSC) illuminated in the instrument panel with Diagnostic Trouble Code (DTC) C1247 (Stroke Sensor Malfunction) stored in the ABS/VSC Electronic Control Unit (ECU). This DTC may set as a result of an overly sensitive monitoring logic without any other ABS/VSC system issue. Follow the Repair Procedure in this bulletin to properly diagnose the system and, if necessary, replace the ABS/VSC ECU with an ECU containing the updated monitoring logic.

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.
