HEATER SWITCH INSPECTION

PROCEDURE

1. INSPECT HEATER SWITCH ASSEMBLY (for Sedan)

   
   
   1. 

      *a	Component without harness connected (Heater Switch Assembly)

      Measure the resistance.

      
      

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

         Standard Resistance
         Tester Connection Condition Specified Condition 4 (IG) - 1 (IN) Heater switch assembly: On Below 1 Ω 4 (IG) - 1 (IN) Heater switch assembly: Off 10 kΩ or higher

   2. Check the operation indicator.

      
      

      1. Turn the heater switch assembly on.

      2. Connect a positive (+) lead from the battery to terminal 4 (IG) and a negative (-) lead to terminal 5 (E), and check that the operation indicator comes on.

         OK
         Indicator comes on.

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

2. INSPECT HEATER SWITCH ASSEMBLY (for Hatchback, Wagon)

   
   
   1. 

      *a	Component without harness connected (Heater Switch Assembly)

      Measure the resistance.

      
      

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

         Standard Resistance
         Tester Connection Condition Specified Condition 8 (IG) - 5 (IN) Heater switch assembly: On Below 1 Ω 8 (IG) - 5 (IN) Heater switch assembly: Off 10 kΩ or higher

   2. Check the operation indicator.

      
      

      1. Turn the heater switch assembly on.

      2. Connect a positive (+) lead from the battery to terminal 8 (IG) and a negative (-) lead to terminal 3 (E), and check that the operation indicator comes on.

         OK
         Indicator comes on.

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