      (Map Light Assembly)

      Connect a positive (+) lead to terminal R12-4 (IND1) or R12-5 (IND2), and a negative (-) lead to terminal R7-16 (GND9) of the map light assembly connector.

    4. Check if the illumination for the emergency call switch comes on.

      OK
      The red indicator comes on when the positive (+) lead from the batteries is connected to terminal R12-4 (IND1) and the negative (-) lead is connected to terminal R7-16 (GND9).
      The green indicator comes on when the positive (+) lead from the batteries is connected to terminal R12-5 (IND2) and the negative (-) lead is connected to terminal R7-16 (GND9).
