      Text in Illustration
      *1 A/C Switch
      *a

      Component without harness connected

      (No. 3 heater control sub-assembly)

      Check the heater control assembly resistance.

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      2(B) - 3(A/C) A/C switch OFF 10 kΩ or higher
      2(B) - 4(AND) A/C switch OFF 10 kΩ or higher
      3(A/C) - 4(AND) Always Below 1 Ω
      2(B) - 3(A/C) A/C switch ON Below 1 Ω
      2(B) - 4(AND) A/C switch ON Below 1 Ω
      5 - 6 Always Below 1 Ω

    3. Check that the A/C Switch illumination.

      OK
      Measurement Condition Specified Condition

      Battery positive (+) → 5

      Battery negative (-) → 6

      		 illuminates

    4. Check that the indicator light.

      Standard
      Tester Connection Switch Condition Specified Condition

      Battery positive (+) → 2

      Battery negative (-) → 4

      		 A/C switch OFF go out

      Battery positive (+) → 2

      Battery negative (-) → 4

      		 A/C switch ON come on

  2. INSPECT HEATER CONTROL SUB-ASSEMBLY

      *a OFF
      *b LO
      *c M1
      *d M2
      *e HI
      *f

      Component without harness connected

      (heater control sub-assembly)

      Check the heater control assembly resistance.

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      each terminal - 5 A/C switch OFF 10 kΩ or higher
      10 - 5 A/C switch LO Below 1 Ω
      10 - 5 - 3 A/C switch LO - M1 Below 1 Ω
      10 - 5 - 3 A/C switch M1 Below 1 Ω
      10 - 5 - 3 - 6 A/C switch M1 - M2 Below 1 Ω
      10 - 5 - 6 A/C switch M2 Below 1 Ω
      10 - 5 - 6 - 1 A/C switch M2 - HI Below 1 Ω
      10 - 5 - 1 A/C switch HI Below 1 Ω

      *1 Rr DEF switch
      *a

      Component without harness connected

      (heater control sub-assembly)

      Check the heater control assembly resistance.

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      2 - 4 Rr DEF switch OFF 10 kΩ or higher
      2 - 4 Rr DEF switch ON Below 1 Ω

    6. Check that the Rr DEF switch illumination.

      OK
      Measurement Condition Specified Condition

      Battery positive (+) → 7

      Battery negative (-) → 5

      		 illuminates

    7. Check that the indicator light.

      Standard
