      *a

      Component without harness connected

      (Electric Parking Brake Switch)
      *b

      Pulled

      (Release)
      *c Neutral
      *d

      Pushed

      (Lock)

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      8 (LOK1) - 7 (LOK2) Neutral 1M Ω or higher
      Pushed (Lock) 1.29 k to 1.32 kΩ
      Pulled (Release) 3.87 k to 3.96 kΩ
      3 (RLS1) - 4 (RLS2) Neutral 1M Ω or higher
      Pushed (Lock) 3.48 k to 3.56 kΩ
      Pulled (Release) 1.36 k to 1.40 kΩ
      7 (LOK2) - 4 (RLS2) Always 2.58 k to 2.64 kΩ
      7 (LOK2) - 3 (RLS1) Neutral 1M Ω or higher
      Pushed (Lock) 890 to 920 Ω
      Pulled (Release) 3.95 k to 4.03 kΩ
      4 (RLS2) - 8 (LOK1) Neutral 1M Ω or higher
      Pushed (Lock) 3.87 k to 3.96 kΩ
      Pulled (Release) 1.29 k to 1.32 kΩ
      3 (RLS1) - 8 (LOK1) Neutral 2.58 k to 2.64 kΩ
      Pushed (Lock) 1.40 k to 1.44 kΩ
      Pulled (Release) 1.53 k to 1.57 kΩ

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