      *a Component without harness connected
      (Seat Heater Switch (LH Side))
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        3 - 9 Seat heater switch on Below 1 Ω
        7 - 9 Seat heater switch off 2.72 to 4.08 kΩ
        Seat heater switch on (Vol: max.) 280 to 420 Ω

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

    2. Check the switch illumination and indicator.
      1. Apply battery voltage to the seat heater switch (LH side) and check that the switch illumination and each indicator come on.

        OK

        Battery Connection Condition Specified Condition
        Battery positive (+) → 9
        Battery negative (-) → 4        		 Seat heater switch on Indicator comes on
        Battery positive (+) → 8
        Battery negative (-) → 2        		 Always Switch illumination comes on

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

  2. INSPECT SEAT HEATER SWITCH (RH SIDE) (w/o Climate Control Seat System) 
    1. Check the seat heater switch (RH side).
