If a malfunction occurs in the actuator or speed sensor, etc. during cruise control opera-tion, the rotor shaft between the motor and control plate is the brake pedal is depressed, the stop lamp switch assy turns ON, supplying electrical power to thestop light. Power supply to the magnetic clutch is mechanically cut and the magnetic clutch is turned driving downhill, if the vehicle speed exceeds the set speed by 8 km/h (5 mph), the ECU turns thesafety magnet clutch OFF. If the vehicle speed later drops to within 5 km/h (3 mph) above the set speed,then cruise control at the set speed is Detecting ConditionTrouble AreaSSTOP FuseSStop lamp switch assySCruise control actuator assy (Actuator magnetic clutch)SActuator magnetic clutch circuitSCruise control ECU assy12SShort in actuator magnetic clutch (0.8 sec.) in actuator magnetic clutch DIAGRAMS9Stop Lamp SwitchAssy2R–WG–W1Instrument Panel J/B5IC14ICSTOP1IL1IBG–W133CRH J/BCruise Control ECU Assy123G–W3CC14STP–W13IA5G–O8C14LEngine Room J/BB11A1ALT211CWS9Stop Lamp Switch AssyR–YG–O34C4Cruise ControlActuator AssyFL MAINW–BAJ6J/CBattery214BCenter J/B13W–B4B3W–BIA54GNDL3IEI241932004 COROLLA (RM1037U)Author?:Date?:922
