    1. Remove the map light for standard body (see page ) or long body Click here.

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

      Standard resistance
      Tester Connection Switch Condition Specified Condition
      A-24 (UP) - A-16 (GND9) TILT UP Below 1 Ω
      A-24 (UP) - A-16 (GND9) Off 10 kΩ or higher
      A-23 (DOWN) - A-16 (GND9) TILT DOWN Below 1 Ω
      A-23 (DOWN) - A-16 (GND9) Off 10 kΩ or higher
      B-3 (OPN) - A-16 (GND9) SLIDE OPEN Below 1 Ω
      B-3 (OPN) - A-16 (GND9) Off 10 kΩ or higher
      B-12 (CLS) - A-16 (GND9) SLIDE CLOSE Below 1 Ω
      B-12 (CLS) - A-16 (GND9) Off 10 kΩ or higher

    OK
