Integration Control And Panel: Inspection

WARNING: This page is about a different car, the 2008 Toyota FJ Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT INTEGRATION CONTROL AND PANEL ASSEMBLY 
    1. Check the blower switch resistance.
      1. Using an ohmmeter, measure the resistance and check the results in accordance with the values in the table below.

        Standard resistance 

        TESTER CONNECTION SPECIFIED CONDITION

        Tester connection Blower Switch Position Specified Condition
        1 - 4 - 5 - 6 - 8 OFF 10 KΩ or higher
        1 - 8 LO Below 1 Ω
        1 - 6 - 8 M1 Below 1 Ω
        1 - 5 - 8 M2 Below 1 Ω
        1 - 4 - 8 HI Below 1 Ω

        If the result is not as specified, replace the integration control and panel assembly.

    2. Inspect the illumination operation.
      1. Connect the positive (+) lead from the battery to terminals 1 (IG+) and 2 (ILL+) and the negative (-) lead to terminal 20 (GND), then check that the illuminations light up.

        Standard: 

        Illuminations light up 

        If the result is not as specified, replace the integration control and panel assembly.

    3. Inspect the A/C indicator operation.
      1. Connect the positive (+) lead from the battery to terminal 1 (IG+) and the negative (-) lead to terminals 8 (BLW) and 20 (GND).
      2. Push the A/C button in and then check that the indicator lights up.

        Standard 

        SWITCH CONDITION

        Switch Condition Specified Condition
        Switch ON Indicator illuminates
        Switch OFF Indicator turns off

        HINT:

        Inspect the A/C indicator operation in any position except MAX COOL. The A/C indicator ON/OFF operation does not function in MAX COOL position (The A/C indicator is held in ON state).

        If the result is not as specified, replace the integration control and panel assembly.

      3. Under the above condition, connect the positive (+) lead from the battery to terminal 2 (ILL+) and then check that the indicator dims.

        Standard 

        SWITCH CONDITION

        Switch Condition Specified Condition
        Switch ON Indicator dims
        Switch OFF Indicator turns off

        HINT:

        Inspect the A/G indicator operation in any position except MAX COOL. The A/C indicator ON/OFF operation does not function in MAX COOL position (The A/C indicator is held in ON state).

        If the result is not as specified, replace the integration control and panel assembly.

    4. Inspect the REC indicator operation.
      1. Connect the positive (+) lead from the battery to terminal 1 (IG+) and the negative (-) lead to terminal 20 (GND).
        NOTE: Inspect the MODE switch in any position except DEF.
      2. Push the REC button in and check that the indicator lights up.

        Standard 

        SWITCH CONDITION

        Switch Condition Specified Condition
        Switch ON Indicator illuminates
        Switch OFF Indicator turns off

        If the result is not as specified, replace the integration control and panel assembly.

      3. Under the above condition, connect the positive (+) lead from the battery to terminal 2 (ILL+) and then check that the indicator dims.
        NOTE: Inspect the MODE switch in any position except DEF.

        Standard 

        SWITCH CONDITION

        Switch Condition Specified Condition
        Switch ON Indicator dims
        Switch OFF Indicator turns off

        If the result is not as specified, replace the integration control and panel assembly.

    5. Inspect the temperature control switch operation.
      1. Connect the positive (+) lead from the battery to terminal 1 (IG+) and the negative (-) lead to terminals 8 (BLW) and 20 (GND).
        NOTE: Inspect the MODE switch in any position other than DEF and FOOT/DEF.
      2. Check the A/C indicator and REC indicator operations when the temperature switch is operated.

        Standard 

        TEMPERATURE SWITCH CONDITION

        Temperature Switch Condition Specified Condition (A/C indicator and REC indicator)
        Except MAX A/C Neither indicator illuminates
        MAX A/C Both indicators illuminate*1
        HINT:
        *1: The A/C indicator remains, illuminated even after the temperature switch is turned from this position to another. The REC indicator returns to the condition prior to turning the switch to MAX A/C. Press the A/C switch in and check that the indicator turns off.
