    2. Disconnect the R7 and R12 map light assembly connectors.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      R12-4 (IND1) - P2-11 (IND1) Always Below 1 Ω
      R12-5 (IND2) - P2-12 (IND2) Always Below 1 Ω
      R7-16 (GND9) - Body ground Always Below 1 Ω
      R12-4 (IND1) - Body ground Always 10 kΩ or higher
      R12-5 (IND2) - Body ground Always 10 kΩ or higher

    2. Connect 2 dry-cell batteries in series.

    3. A01WWL6E17

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

    4. Check if an emergency call switch indicator comes on.

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