      Standard Resistance
      Tester Connection Switch Condition Specified Condition 5 (IGL) - 6 (LH) "L" switch off 10 kΩ or higher 5 (IGL) - 6 (LH) "L" switch on Below 1 Ω 4 (IGR) - 3 (RH) "R" switch off 10 kΩ or higher 4 (IGR) - 3 (RH) "R" switch on Below 1 Ω

      If the result is not as specified, replace the seat heater switch.

   2. Check that the seat heater switch indicator illuminates.

      
      

      1. Apply battery voltage to the seat heater switch and check that the seat heater switch indicator illuminates.

         OK
         Measurement Connection Switch Condition Specified Condition Battery positive (+) → 5 (IGL) Battery negative (-) → 2 (E) "L" switch on Illuminates Battery positive (+) → 4 (IGR) Battery negative (-) → 2 (E) "R" switch on Illuminates

         If the result is not as specified, replace the seat heater switch.

   3. Check that the seat heater switch illuminates.
