Remove the map light ().

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

  • Standard Resistance:
  • Tester ConnectionSwitch ConditionSpecified Condition
    19 (UP) - 17 (GND9)UP switch is pressed Below 1 Ω
    19 (UP) - 17 (GND9)UP switch is not pressed 10 kΩ or higher
    18 (DOWN) - 17 (GND9)DOWN switch is pressed Below 1 Ω
