VDC Control Module And Hydraulic Control Unit (VDCCM And H/U): Installation

CAUTION:
  • When installing the VDC control module and H/U to the VDC control module and H/U bracket, make sure that there is no oil adhered to the bolts and the threads of VDC control module and H/U. If the oil is adhered, degrease it carefully before tightening.
  • Connect the VDC control module and H/U connector securely.
  1. Install the bracket COMPL hydraulic unit VDC and the hydraulic unit assembly VDC.
    1. Attach the bracket COMPL hydraulic unit VDC.

      Tightening torque: 

      33 N.m (3.4 kgf-m, 24.3 ft-lb)

    2. Install the bracket hydraulic unit adapter to the hydraulic unit assembly VDC.

      Tightening torque: 

      27 N.m (2.8 kgf-m, 19.9 ft-lb)

    3. Install the hydraulic unit sub assembly to the bracket COMPL hydraulic unit VDC.

      Tightening torque: 

      7.5 N.m (0.8 kgf-m, 5.5 ft-lb)

    4. Connect the hydraulic unit assembly VDC connector.
    5. Install the pipe assembly front ABS using a flare nut wrench.

      Tightening torque: 

      Refer to "COMPONENT" of "General Description" for the tightening torque. Ref. to BRAKE>GENERAL DESCRIPTION>COMPONENT>FRONT BRAKE PIPES AND HOSES .

  2. Install the air intake boot.
  3. Connect the ground terminal to battery sensor. Ref. to REPAIR CONTENTS>NOTE>BATTERY .
  4. Bleed air from the brake system. Ref. to BRAKE>AIR BLEEDING>PROCEDURE .
  5. Perform parameter confirmation, selection, and registration.
    NOTE:
    • When the VDC control module and H/U is replaced with a new part, be sure to perform the parameter selection/registration.
    • When the registration has not been performed, the DTC code [SELECTED PARAMETER] is detected together with the ABS/EBD/VDC warning light illumination.
    1. Check that the applied model and grade of the relevant vehicle are included. Ref. to VEHICLE DYNAMICS CONTROL (VDC)>VDC CONTROL MODULE AND HYDRAULIC CONTROL UNIT (VDCCM and H/U)>MAINTENANCE MODE>VDCCM PARAMETER CHECK .
    2. If the applied model and grade of the target vehicle are not included, perform "parameter selection and registration". Ref. to VEHICLE DYNAMICS CONTROL (VDC)>VDC CONTROL MODULE AND HYDRAULIC CONTROL UNIT (VDCCM and H/U)>MAINTENANCE MODE>VDCCM PARAMETER SELECTION .
  6. Perform "VDC sensor midpoint setting mode". Ref. to VEHICLE DYNAMICS CONTROL (VDC)>VDC CONTROL MODULE AND HYDRAULIC CONTROL UNIT (VDCCM and H/U)>ADJUSTMENT>VDC SENSOR MIDPOINT SETTING MODE .
