MAYDAY SWITCH INSPECTION

PROCEDURE

  1. REMOVE MAP LIGHT ASSEMBLY

  2. INSPECT MAP LIGHT ASSEMBLY

    1. Check the resistance.

      1. E348966C01

        *a

        Component without harness connected

        (Map Light Assembly)

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

        Resistance

        Tester Connection

        Condition

        Specified Condition

        9 (SIG1) - 10 (GND3)

        Mayday switch not pressed

        410 to 414 Ω

        9 (SIG1) - 10 (GND3)

        Mayday switch pressed

        81 to 83 Ω

    2. Check the operation (indicator).

      1. E348949C01

        *a

        Component without harness connected

        (Map Light Assembly)

        *b

        Two 1.5 V dry cell batteries

        Check that each indicator illuminates when 2 dry cell batteries are connected to the map light assembly connector terminals as shown in the illustration.

        Note:

        Do not apply more than 3 V.

        OK

        Tester Connection

        Condition

        Specified Condition

        11 (IND1) - 20 (GND)

        Positive (+) dry cell battery - Negative (-) dry cell battery

        HELP RED indicator illuminates

        12 (IND2) - 20 (GND)

        Positive (+) dry cell battery - Negative (-) dry cell battery

        HELP GREEN indicator illuminates

    3. E348966C02

      *a

      Component without harness connected

      (Map Light Assembly)

      Check that the HELP indicator illuminates when the battery is connected to the map light assembly connector terminals as shown in the illustration.

      OK

      Tester Connection

      Condition

      Specified Condition

      2 (RRID) - 20 (GND)

      Positive (+) battery terminal - Negative (-) battery terminal

      HELP indicator illuminates

  3. INSTALL MAP LIGHT ASSEMBLY
