SEAT HEATER SWITCH(for Rear Side) INSPECTION

PROCEDURE

1. INSPECT SEAT HEATER SWITCH (for LH Side)

   
   

   1. Check the seat heater switch

      
      
      1. 

         *a	Component without harness connected (Seat Heater Switch (for LH Side))

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

         Standard Resistance (for LO Side)
         Tester Connection Switch Condition Specified Condition 2 (IG) - 1 (LO) Lo switch on Below 1 Ω 2 (IG) - 1 (LO) Lo switch off 10 kΩ or higher

         Standard Resistance (for HI Side)
         Tester Connection Switch Condition Specified Condition 2 (IG) - 3 (HI) Hi switch on Below 1 Ω 2 (IG) - 3 (HI) Hi switch off 10 kΩ or higher

         If the specified condition is not met, replace the seat heater switch (for LH Side).

   2. Check the switch indicator.

      
      

      1. Apply auxiliary battery voltage to the seat heater switch and check that the switch indicator come on.

         OK (for LO Side)
         Measurement Condition Switch Condition Specified Condition Auxiliary battery positive (+) → 2 (IG) Auxiliary battery negative (-) → 6 (E) Lo switch on Illuminates

         OK (for HI Side)
         Measurement Condition Switch Condition Specified Condition Auxiliary battery positive (+) → 2 (IG) Auxiliary battery negative (-) → 6 (E) Hi switch on Illuminates

         If the specified condition is not met, replace the seat heater switch (for LH Side).

   3. Check the switch illumination.

      
      

      1. Apply auxiliary battery voltage to the seat heater switch and check that the switch illumination come on.

         OK
         Measurement Condition Switch Condition Specified Condition Auxiliary battery positive (+) → 4 (ILL+) Auxiliary battery negative (-) → 5 (ILL-) Always Illuminates

         If the specified condition is not met, replace the seat heater switch (for LH Side).

2. INSPECT SEAT HEATER SWITCH (for RH Side)

   

   *a	Component without harness connected (Seat Heater Switch (for RH Side))

   
   

   1. Check the seat heater switch

      
      

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

         Standard Resistance (for LO Side)
         Tester Connection Switch Condition Specified Condition 3 (IG) - 1 (LO) Lo switch on Below 1 Ω 3 (IG) - 1 (LO) Lo switch off 10 kΩ or higher

         Standard Resistance (for HI Side)
         3 (IG) - 4 (HI) Tester Connection Switch Condition Specified Condition 3 (IG) - 4 (HI) Hi switch on Below 1 Ω 3 (IG) - 4 (HI) Hi switch off 10 kΩ or higher 1 (LO) - 10 (E) Hi switch on Below 1 Ω 1 (LO) - 10 (E) Hi switch off 10 kΩ or higher

         If the specified condition is not met, replace the seat heater switch (for RH Side).

   2. Check the switch indicator.

      
      

      1. Apply auxiliary battery voltage to the seat heater switch and check that the switch indicator come on.

         OK (for LO Side)
         Measurement Condition Switch Condition Specified Condition Auxiliary battery positive (+) → 3 (IG) Auxiliary battery negative (-) → 10 (E) Lo switch on Illuminates

         OK (for HI Side)
         Measurement Condition Switch Condition Specified Condition Auxiliary battery positive (+) → 3 (IG) Auxiliary battery negative (-) → 10 (E) Hi switch on Illuminates

         If the specified condition is not met, replace the seat heater switch (for RH Side).

   3. Check the switch illumination.

      
      

      1. Apply auxiliary battery voltage to the seat heater switch and check that the switch illumination come on.

         OK
         Measurement Condition Switch Condition Specified Condition Auxiliary battery positive (+) → 6 (ILL+) Auxiliary battery negative (-) → 8 (ILL-) Always Illuminates

         If the specified condition is not met, replace the seat heater switch (for RH Side).
