>> A < Install the wiper blade at the specified position (standard value). Standard value (A): 25 +/- 5 mm (0.98 +/- 0.20 inch) >> B < CAUTION: For good windshield wiper wiping performance, use a passenger-side windshield wiper without an curve in the backing of the wiper blade. The windshield wiper on the driver's side should be a wiper blade with a curved backing. INSPECTION WINDSHIELD WIPER MOTOR CHECK Inspect the windshield wiper motor by removing the harness connector with the motor attached to the vehicle. Wiper Motor At Low-Speed And High-Speed Operation Connect the battery to the windshield wiper motor to inspect the operation of motor rotation in low or high speed. Wiper Motor At Stop Position Operation Connect the battery to the windshield wiper motor as shown in the illustration (A). Run the windshield wiper motor at low speed, then disconnect the battery in the middle of the motor turning and check to see that the motor stops. As shown in the illustration (B), connect the terminals of the windshield wiper motor connectors. Check to see that the windshield wiper motor runs at low speed and then stops at the automatic stop position. WINDSHIELD WIPER SWITCH CHECK Check continuity between the switch terminals. TESTER CONNECTION SPECIFIED CONDITION SWITCH POSITION TESTER CONNECTION SPECIFIED CONDITION OFF 6 - 11, 6 - 10, 6 - 9, 6 - 8 Open circuit Windshield mist wiper switch 6 - 11 Less than 2 ohms Windshield intermittent wiper switch 6 - 10 Less than 2 ohms Windshield low-speed wiper switch 6 - 9 Less than 2 ohms Windshield high-speed wiper switch 6 - 8 Less than 2 ohms WINDSHIELD INTERMITTENT WIPER VOLUME CHECK Check that the resistance varies between 0 and 1 when the windshield intermittent volume is turned from FAST to SLOW by after measuring resistance between connector terminals 3 and 6 at the column switch. WINDSHIELD WASHER REMOVAL AND INSTALLATION NOTE: For removal and installation of the wiper and washer switch, refer to COLUMN SWITCH . INSPECTION WINDSHIELD WASHER MOTOR CHECK Remove the washer tank assembly with the washer hose attached. Then fill the washer tank with water. Check to see that the water is vigorously sprayed when connecting the positive battery terminal to terminal number 2 and terminal number 1 to the negative battery terminal. WINDSHIELD WASHER FLUID EJECTION CHECK Move the nozzle to adjust the position so that the washer fluid is sprayed in the area shown in the illustration. WINDSHIELD WASHER SWITCH CHECK Check continuity between the switch terminals. TESTER CONNECTION SPECIFIED CONDITION SWITCH POSITION TESTER CONNECTION SPECIFIED CONDITION OFF 6 - 7 Open circuit Windshield washer switch 6 - 7 Less than 2 ohms REAR WIPER AND WASHER GENERAL DESCRIPTION REAR WIPER OPERATION If the rear wiper and washer switch is turned to "INT" position with the ignition switch at "ACC" or "ON" position, the ETACS-ECU turns ON the rear wiper drive signal for 3 seconds (approximately two cycles), then 7.4 seconds later the intermittent motion operates every 8 seconds. If the selector lever is moved to the "R" position when the rear wiper and washer switch is turned to the "INT" position and the ignition switch is at the "ACC" or "ON" position, the park/neutral position switch "R" turns ON. 1 second later, the ETACS-ECU turns ON the rear wiper drive signal for 3 seconds (approximately two cycles). Then, 7.4 seconds later, the intermittent motion of 8 seconds' cycle is restored. REAR WIPER AND WASHER DIAGNOSIS The rear wiper and washer are controlled by the Simplified Wiring System (SWS). For troubleshooting, refer to SWS DIAGNOSIS . REAR WASHER OPERATION If the rear wiper and washer switch is turned to the ON (washer) position with the ignition switch at the "ACC" or "ON" position, the rear washer ON signal is sent to the ETACS-ECU, causing the rear wiper signal to turn on after 0.3 second. After the rear washer switch signal turns off, the rear wiper signal turns off in 3 seconds. If the rear washer switch is turned to the ON position while the rear wiper is in intermittent mode, the rear washer works for that period when the washer switch remains on. Then the rear wipers return to the intermittent mode. ON-VEHICLE SERVICE CHECK OF REAR WIPER OPERATION WHEN SELECTOR LEVER IS AT THE "R" POSITION When the selector lever is moved to the "R" position with the rear wiper switch at the "INT" position, the wiper should operate twice or three times at low speed after approximately one second. If not, troubleshoot (Refer to DIAGNOSIS ). REMOVAL AND INSTALLATION NOTE: For removal and installation of the wiper and washer switch, refer to COLUMN SWITCH . INSTALLATION SERVICE POINTS >> A < Before installing the rear wiper arm and blade assembly, operate the rear wiper motor so that the motor stops at the predetermined park position. Install the rear wipe arm and blade assembly and adjust the rear wiper blade position so that the blade end stops at the predetermined position (standard position). Standard value (A): 30 +/- 5 mm (1.18 +/- 0.20 inch) >> B < CAUTION: Use a curved backing like that shown for the backing of a wiper blade to ensure sustained wiper wiping performance. INSPECTION REAR WIPER MOTOR CHECK Inspect the rear wiper motor by removing the harness connector with the motor attached to the vehicle. WIPER MOTOR OPERATION Connect the battery to the rear wiper motor as shown in figure (A) and check the motor operation. WIPER MOTOR AT STOP POSITION OPERATION Connect the battery to the rear wiper motor as shown in figure (A). Disconnect the battery cable from the rear windshield wiper motor while it is turning and then check to see that the motor stops. Re-connect the battery as shown in figure (B). Check to see that the rear windshield wiper motor runs and then stops at the automatic stop position. REAR WASHER MOTOR CHECK Remove the rear washer tank assembly with the washer hose attached. Then fill the washer tank with water. Check to see that the water is vigorously sprayed when connecting the positive battery terminal to terminal number 2 and terminal number 1 to the negative battery terminal. REAR WASHER FLUID EJECTION CHECK Move the nozzle to adjust the position so that the spray is in the area shown in the illustration. REAR WIPER AND WASHER SWITCH CHECK Check continuity between the switch terminals.
