      *a Procedure Necessary to Prevent Electrostatic Discharge - -

      Note


      • Do not touch any IC, circuit trace or circuit element without taking measures to prevent electrostatic discharge.

      • Insert the gear of the heater control housing sub-assembly perpendicular to the No. 1 center cluster module circuit sub-assembly.

      • The metal cover of the encoder can easily come off, so hold the cover in place while inserting the gear.

      • Do not place excessive force on the dials of the heater control housing sub-assembly.

      • Do not allow oil, grease or other foreign matter to contact the heater control housing sub-assembly and prevent it from being damaged.

      • After installing the heater control housing sub-assembly with the screws, remove the tape fixing the dials in place from the new heater control housing sub-assembly.

    2. Check that the slit or hole of the gear and the hole of the housing are positioned as shown in the illustration.

      Note


      • Be careful not to break the positioning pins on the heater control housing sub-assembly.

      • Be careful not to damage the circuit board of the No. 1 center cluster module circuit sub-assembly.

  2. INSTALL CONTROL KNOB SUB-ASSEMBLY


    1. for Automatic Air Conditioning System:

      Install the control knob sub-assembly.


      1. Install the control knob sub-assembly and No. 1 center cluster module circuit sub-assembly to the front air conditioning panel sub-assembly.

        Tech Tips

        Position the control knob sub-assembly so that the knobs face upwards and, while holding the front air conditioning panel sub-assembly parallel to the control knob sub-assembly, place the front air conditioning panel sub-assembly onto the control knob sub-assembly to install it.

        Note


        • Be sure not to allow skin oils, grease, foreign matter, etc. to adhere to the parts and be sure not to damage the parts.

        • When installing the control knob sub-assembly and No. 1 center cluster module circuit sub-assembly to the front air conditioning panel sub-assembly, make sure that the ribs are properly engaged as shown in the illustration.

        • Do not apply excessive force to the knobs when installing the control knob sub-assembly as the knobs break easily.

        • Do not touch any IC, circuit trace or circuit element without taking measures to prevent electrostatic discharge.

      2. Install the 6 screws.

        Note


        • Be sure not to allow skin oils, grease, foreign matter, etc. to adhere to the parts and be sure not to damage the parts.

        • Do not touch any IC, circuit trace or circuit element without taking measures to prevent electrostatic discharge.

        • Do not damage the No. 1 center cluster module circuit sub-assembly when tightening the screws.

    2. for Manual Air Conditioning System:

      Install the control knob sub-assembly.


      1. Install the control knob sub-assembly and No. 1 center cluster module circuit sub-assembly to the front air conditioning panel sub-assembly.

        Note


        • Be sure not to allow skin oils, grease, foreign matter, etc. to adhere to the parts and be sure not to damage the parts.

        • When installing the knob sub-assembly and No. 1 center cluster module circuit sub-assembly to the front case sub-assembly, make sure that the ribs are properly engaged as shown in the illustration.

        • Do not apply excessive force to the knobs when installing the knob sub-assembly as the knobs break easily.

        • Do not touch any IC, circuit trace or circuit element without taking measures to prevent electrostatic discharge.

      2. Install the 6 screws.
