        *d M2
        *e HI
        *f

        Component without harness connected

        (No. 2 Heater Control Sub-assembly)

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

        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        ALL - 5 (E) 0 (OFF) 10 kΩ or higher
        9 (LO) - 5 (E) 1 (LO) Below 1 Ω
        9 (LO) - 5 (E) - 7 (M1) 1 (LO) - 2 (M1) Below 1 Ω
        9 (LO) - 5 (E) - 7 (M1) 2 (M1) Below 1 Ω
        9 (LO) - 5 (E) - 7 (M1) - 6 (M2) 2 (M1) - 3 (M2) Below 1 Ω
        9 (LO) - 5 (E) - 6 (M2) 3 (M2) Below 1 Ω
        9 (LO) - 5 (E) - 10 (HI) - 6 (M2) 3 (M2) - 4(HI) Below 1 Ω
        9 (LO) - 5 (E) - 10 (HI) 4 (HI) Below 1 Ω

        If the result is not as specified, replace the No. 2 heater control sub-assembly.

    2. Check that the heater control illuminates.


      1. Apply battery voltage to the heater control sub-assembly and check that the heater control sub-assembly illuminates.

        OK
        Measurement Condition Specified Condition

        Battery positive (+) → 2(ILL+)

        Battery negative (-) → 1(ILL-)

        		 illuminates

        If the result is not as specified, replace the bulb.

  3. INSPECT NO. 3 HEATER CONTROL SUB-ASSEMBLY


    1. Check the No. 3 heater control sub-assembly resistance.

        Text in Illustration
        *1 Rr Defogger Switch
        *a MAX HOT
        *b

        Component without harness connected

        (No. 3 Heater Control Sub-assembly)

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        2 (Rr DEF) - 1(E) Rear window defogger switch on Below 1 Ω
        Rear window defogger switch off 10 kΩ or higher
        3 (IG) - 6 (MAX-HOT) MAX HOT Below 1 Ω
        Except MAX HOT 10 kΩ or higher
        7 (V/B) - 8 (SG) Always Below 1 Ω

        If the result is not as specified, replace the No. 3 heater control sub-assembly.

      2. Measure the resistance according to the value(s) in the table below (for Cold Area Specification Vehicles).

        Standard Resistance
        Tester Connection Condition Specified Condition

        Except MAX HOT 10 kΩ or higher

        If the result is not as specified, replace the No. 3 heater control sub-assembly.

    2. Check that the rear window defogger indicator.


      1. Connect the positive (+) lead from the battery to terminal 3 (IG) and the negative (-) lead to terminal 1 (E).

      2. Push the rear window defogger switch in and check that the indicator lights up.

        OK
        Indicator lights up

        • If the result is not as specified, replace the No. 3 heater control sub-assembly.

    3. Check that the heater control illuminates.


      1. Apply battery voltage to the heater control sub-assembly and check that the heater control sub-assembly illuminates.

        OK
        Measurement Condition Specified Condition

        Battery positive (+) → 5(ILL+)
