      *a Component without harness connected
      (Multi-Terrain Select Switch (No. 1 Pattern Select Switch Assembly))

      Standard Resistance

      Tester Connection Condition Specified Condition
      6 (B) - 3 (E) NORMAL mode switch being pushed and held 80.4 to 83.6 Ω
      NORMAL mode switch not pushed 10 kΩ or higher
      6 (B) - 3 (E) ROCK & DIRT mode switch being turned and held 580.2 to 603.8 Ω
      ROCK & DIRT mode switch not turned 10 kΩ or higher
      6 (B) - 3 (E) MUD & SAND mode switch being turned and held 2.050 to 2.134 kΩ
      MUD & SAND mode switch not turned 10 kΩ or higher

      If the result is not as specified, replace the No. 1 pattern select switch assembly.

    2. Apply battery voltage between the terminals of the switch and check the illumination condition of the multi-terrain select switch (No. 1 pattern select switch assembly).
