MAYDAY SWITCH INSPECTION

PROCEDURE


  1. INSPECT MAYDAY SWITCH (MAP LIGHT SUB-ASSEMBLY)


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

      B004C75C06
      *a

      Component without harness connected

      (Mayday Switch (Map Light Sub-Assembly))

      		 - -
      Standard Resistance
      Tester Connection Condition Specified Condition
      6 (SIG1) - 10 (GND3) Manual (SOS) switch not pressed 408 to 416 Ω
      6 (SIG1) - 10 (GND3) Manual (SOS) switch pressed 81.2 to 82.8 Ω

      If the result is not as specified, replace the mayday switch (map light sub-assembly).

    2. Inspect the operation (red indicator)


      1. Check that each indicator illuminates when auxiliary battery are connected to the map light sub-assembly connector terminals.

        B004C75C07
        *a

        Component without harness connected

        (Mayday Switch (Map Light Sub-Assembly))

        		 - -
        OK
        Connection operation

        Auxiliary battery positive (+) → 8 (IND1)

        Auxiliary battery negative (-) - 10 (GND3)

        		 Red indicator comes on.

        If the result is not as specified, replace the mayday switch (map light sub-assembly).

    3. Inspect the operation (green indicator)


      1. Check that each indicator illuminates when auxiliary battery are connected to the map light sub-assembly connector terminals.

        B004C75C08
        *a

        Component without harness connected

        (Mayday Switch (Map Light Sub-Assembly))

        		 - -
        OK
        Connection operation

        Auxiliary battery positive (+) → 9 (IND2)

        Auxiliary battery negative (-) - 10 (GND3)

        		 Green indicator comes on.

        If the result is not as specified, replace the mayday switch (map light sub-assembly).

    4. Inspect the operation (HELP indicator)


      1. Check that each indicator illuminates when auxiliary battery are connected to the map light sub-assembly connector terminals.

        B004C75C09
        *a

        Component without harness connected

        (Mayday Switch (Map Light Sub-Assembly))

        		 - -
        OK
        Connection operation

        Auxiliary battery positive (+) → 7 (RRID)

        Auxiliary battery negative (-) - 10 (GND3)

        		 HELP indicator comes on.

        If the result is not as specified, replace the mayday switch (map light sub-assembly).
