      (Adjusting Ring Position)

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

      Standard Resistance
      Front Wiper Switch
      Tester Connection Switch Condition Specified Condition
      E16-1 (+S) - E16-3 (+1) OFF Below 1 Ω
      E16-2 (+B) - E16-3 (+1) MIST
      LO

      E16-1 (+S) - E16-3 (+1)

      E16-8 (AUTO) - E16-9 (E)

      		 AUTO
      E16-2 (+B) - E16-4 (+2) HI
      Adjusting Ring
      Tester Connection Switch Condition Specified Condition
      E16-7 (VR1) - E16-6 (VR2) P1 209 to 231 Ω
      P2 114 to 126 Ω
      P3 58.9 to 65.1 Ω
      P4 Below 1 Ω
      Front Washer Switch
      Tester Connection Switch Condition Specified Condition
      E15-4 (EW) - E15-7 (WF) ON Below 1 Ω
      OFF 10 kΩ or higher
      Rear Wiper Switch
      Tester Connection Switch Condition Specified Condition

      E15-4 (EW) - E15-2 (C1R)

      E15-4 (EW) - E15-3 (+1R)

      		 OFF 10 kΩ or higher
      E15-4 (EW) - E15-2 (C1R) INT Below 1 Ω
      E15-4 (EW) - E15-3 (+1R) ON
      Rear Washer Switch
      Tester Connection Switch Condition Specified Condition
      E15-4 (EW) - E16-5 (WR) ON Below 1 Ω
      OFF 10 kΩ or higher

      If the result is not as specified, replace the windshield wiper switch assembly.
