Toyota Yaris XP210 (2020-2024) Owner's Manual: Wiper Blades
Contamination of either the windshield or the blades with foreign matter can reduce wiper effectiveness. Common sources are insects, tree sap, and hot wax treatments used by some commercial car washes. If the blades are not wiping properly, clean the window and blades with a good cleaner or mild detergent; then rinse thoroughly with clean water...
Toyota Yaris XP210 (2020-2024) Reapir and Service Manual: 4WD/AWD Range Actuator Temperature Sensor Circuit Range/Performance Circuit Voltage Out of Range (C11411C)
DESCRIPTION When a malfunction has occurred in the AWD coupling solenoid system, the AWD ECU assembly stores DTC C11411C. DTC No. Detection Item DTC Detection Condition Trouble Area Warning Indicate Memory C11411C 4WD/AWD Range Actuator Temperature Sensor Circuit Range/Performance Circuit Voltage Out of Range Even though it can be inferred from the driving conditions that the coupling is generating a significant amount of heat, the temperature sensor value is approximately -10°C (14°F) for 1 second or more, and this continues despite the ignition switch being turned off and then ON again 2 times Even though the engine coolant temperature received from the ECM is less than 35°C (95°F), the temperature sensor value is fixed at 155°C (311°F) (short circuit condition), and this continues despite the ignition switch being turned off and then ON again 2 times The temperature sensor power source voltage is 0...
