   NG

   REPLACE WINDSHIELD WIPER SWITCH ASSEMBLY Click here

   OK

2. CHECK HARNESS AND CONNECTOR (WINDSHIELD WIPER SWITCH ASSEMBLY - BATTERY AND BODY GROUND)

   
   
   1. 

      *A	for RH Side Type
      *B	for LH Side Type
      *a	Front view of wire harness connector (to Windshield Wiper Switch Assembly)

      Disconnect the windshield wiper assembly connectors.

   2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      for RH Side Type Tester Connection Condition Specified Condition G10-4 (EW) -Body ground Always Below 1 Ω
      for LH Side Type Tester Connection Condition Specified Condition G61-7 (EW) -Body ground Always Below 1 Ω

   3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      for RH Side Type Tester Connection Switch Condition Specified Condition G11-2 (+B) -Body ground Ignition switch ON 11 to 14 V Ignition switch off Below 1 V G11-10 (+B2) -Body ground Ignition switch ON 11 to 14 V Ignition switch off Below 1 V
      for LH Side Type Tester Connection Switch Condition Specified Condition G62-3 (+B) -Body ground Ignition switch ON 11 to 14 V Ignition switch off Below 1 V G62-5 (+B2) -Body ground Ignition switch ON 11 to 14 V Ignition switch off Below 1 V

      Result
      Proceed to OK NG

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

3. CHECK HARNESS AND CONNECTOR (WINDSHIELD WIPER SWITCH ASSEMBLY - WINDSHIELD WIPER RELAY ASSEMBLY)

   
   

   1. Disconnect the G10*1 and G11*1 or G61*2 and G62*2 windshield wiper switch assembly connectors.

      
      

      • *1: for RH Side Type

      • *2: for LH Side Type

   2. Disconnect the G85 windshield wiper relay assembly connector.

   3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      for RH Side Type Tester Connection Condition Specified Condition G11-4 (+2) - G85-11 (+2) Always Below 1 Ω G10-7 (WF) - G85-25 (W) Always Below 1 Ω G11-1 (+S) - G85-10 (+1) Always Below 1 Ω G11-6 (VR2) - G85-8 (VR2) Always Below 1 Ω G11-7 (VR1) - G85-21 (VR1) Always Below 1 Ω G11-8 (AUTO) - G85-3 (C1) Always Below 1 Ω G11-9 (E) - G85-5 (C0) Always Below 1 Ω G11-4 (+2) - Body ground Always 10 kΩ or higher G10-7 (WF) - Body ground Always 10 kΩ or higher G11-1 (+S) - Body ground Always 10 kΩ or higher G11-6 (VR2) - Body ground Always 10 kΩ or higher G11-7 (VR1) - Body ground Always 10 kΩ or higher G11-8 (AUTO) - Body ground Always 10 kΩ or higher G11-9 (E) - Body ground Always 10 kΩ or higher
      for LH Side Type Tester Connection Condition Specified Condition G62-1 (+2) - G85-11 (+2) Always Below 1 Ω G61-4 (WF) - G85-25 (W) Always Below 1 Ω G62-4 (+S) - G85-10 (+1) Always Below 1 Ω G62-8 (VR2) - G85-8 (VR2) Always Below 1 Ω G62-9 (VR1) - G85-21 (VR1) Always Below 1 Ω G62-7 (AUTO) - G85-3 (C1) Always Below 1 Ω G62-6 (E) - G85-5 (C0) Always Below 1 Ω G62-1 (+2) - Body ground Always 10 kΩ or higher G61-4 (WF) - Body ground Always 10 kΩ or higher G62-4 (+S) - Body ground Always 10 kΩ or higher G62-8 (VR2) - Body ground Always 10 kΩ or higher G62-9 (VR1) - Body ground Always 10 kΩ or higher G62-7 (AUTO) - Body ground Always 10 kΩ or higher G62-6 (E) - Body ground Always 10 kΩ or higher
