PROCEDURE

  1. INSPECT SEAT HEATER SWITCH (FOR LH)

    1. B332784C01

      *a

      Component without harness connected

      (Seat Heater Switch (for LH))

      Check the seat heater switch (for LH).

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

        Standard Resistance

        Tester Connection

        Condition

        Specified Condition

        2 - 1

        HI switch on

        Below 1 Ω

        2 - 1

        HI switch off

        10 kΩ or higher

        2 - 3

        LO switch on

        Below 1 Ω

        2 - 3

        LO switch off

        10 kΩ or higher

        If the result is not as specified, replace the seat heater switch (for LH).

    2. Check that each LED illuminates.

      1. Apply battery voltage to the seat heater switch (for LH) and check that each LED illuminates.

        OK

        Battery Connection

        Condition

        Specified Condition

        Battery positive (+) → 2

        Battery negative (-) → 6

        HI switch on

        Comes on

        (Yellow)

        Battery positive (+) → 2

        Battery negative (-) → 6

        LO switch on

        Comes on

        (Yellow)

        Battery positive (+) → 5

        Battery negative (-) → 4

        Always

        Comes on

        (Clear blue)

        If the result is not as specified, replace the seat heater switch (for LH).

  2. INSPECT SEAT HEATER SWITCH (FOR RH)

    1. B332785C01

      *a

      Component without harness connected

      (Seat Heater Switch (for RH))

      Check the seat heater switch (for RH).

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

        Standard Resistance

        Tester Connection

        Condition

        Specified Condition

        3 - 2

        HI switch on

        Below 1 Ω

        3 - 2

        HI switch off

        10 kΩ or higher

        3 - 4

        LO switch on

        Below 1 Ω

        3 - 4

        LO switch off

        10 kΩ or higher

        If the result is not as specified, replace the seat heater switch (for RH).

    2. Check that each LED illuminates.

      1. Apply battery voltage to the seat heater switch (for RH) and check that each LED illuminates.

        OK

        Battery Connection
