AIR CONDITIONING PANEL(for Manual Air Conditioning System) INSPECTION

PROCEDURE


  1. INSPECT AIR CONDITIONING CONTROL ASSEMBLY


    1. B003MAMC01
      *a

      Component without harness connected

      (Air Conditioning Control Assembly)

      Check the blower switch resistance.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        9 (LO), 6 (HI), 8 (M1) or 10 (M2) - 5 (E) OFF 10 kΩ or higher
        9 (LO) - 5 (E) Blower Switch 1 Below 1 Ω
        9 (LO) or 8 (M1) - 5 (E) Blower Switch 1 - 2 Below 1 Ω
        9 (LO) or 8 (M1) - 5 (E) Blower Switch 2 Below 1 Ω
        9 (LO), 8 (M1) or 10 (M2) - 5 (E) Blower Switch 2 - 3 Below 1 Ω
        9 (LO) or 10 (M2) - 5 (E) Blower Switch 3 Below 1 Ω
        9 (LO), 6 (HI) or 10 (M2) - 5 (E) Blower Switch 3 - 4 Below 1 Ω
        9 (LO) or 6 (HI) - 5 (E) Blower Switch 4 Below 1 Ω

        If the result is not as specified, replace the air conditioning control assembly.

    2. B003OPNC11
      *a

      Component without harness connected

      (Air Conditioning Control Assembly)

      Check the A/C switch resistance.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        9 (ACE) - 4 (A/C) OFF 10 kΩ or higher
        9 (ACE) - 4 (A/C) ON Below 1 Ω

        If the result is not as specified, replace the air conditioning control assembly.

    3. B003LF4C02
      *a

      Component without harness connected

      (Air Conditioning Control Assembly (A/C Switch))
      *b Indicator

      Check that the A/C switch LED illuminates.


      1. Apply battery voltage to the air conditioning control assembly (A/C switch) and check that the LED illuminates.

        OK
        Measurement Condition Condition Specified Condition

        Battery positive (+) → 7 (B)

        Battery negative (-) → 9 (ACE)

        		 A/C Switch ON Indicator illuminates

        If the result is not as specified, replace the air conditioning control assembly.

    4. B003OPNC08
      *a

      Component without harness connected

      (Air Conditioning Control Assembly)

      Check the recirculation/fresh switch resistance.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 (FRS) - 5 (ERDF) OFF Below 1 Ω
        2 (LED+) - 5 (ERDF) OFF 10 kΩ or higher
        2 (LED+) - 5 (ERDF) ON Below 1 Ω
        1 (FRS) - 5 (ERDF) ON 10 kΩ or higher

        If the result is not as specified, replace the air conditioning control assembly.

    5. B003Q6DC01
      *a

      Component without harness connected

      (Air Conditioning Control Assembly (recirculation/fresh switch))
      *b Indicator

      Check that the recirculation/fresh switch LED illuminates.


      1. Apply battery voltage to the air conditioning control assembly (recirculation/fresh switch) and check that the LED illuminates.

        OK
        Measurement Condition Switch Position Specified Condition

        Battery positive (+) → 3 (IG)

        Battery negative (-) → 5 (ERDF)

        		 Recirculation/fresh switch: ON Indicator illuminates

        If the result is not as specified, replace the air conditioning control assembly.
