Affected Component: SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE

Summary
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.
