AYC Bleeding

WARNING: This page is about a different variant/trim than selected.
CAUTION: At low temperature the fluid viscosity is so high that air bleeding becomes degenerated. Air bleeding should be done at normal temperatures {10 to 30°C (50 to 86°F)}.
  1. Lift up the vehicle.
    CAUTION: Turn the ignition switch to the "LOCK (OFF)" position before connecting or disconnecting the scan tool.
  2. Set the scan tool to the 16-pin data link connector. (Refer to HOW TO CONNECT THE SCAN TOOL (M.U.T.-III)  .)
  3. Turn the ignition switch to the "ON" position.
  4. Set the steering wheel in the straight-ahead position.
  5. Using the scan tool, forcibly activate the hydraulic unit (item No. 02). (Refer to ACTUATOR TEST TABLE .)
    NOTE:
    • Forced activation (air bleeding mode) is continued for 5 minutes, and then the operation is canceled automatically. Also, using the clear key on the scan tool, the forced activation can be canceled.
    • When the functions are suspended by the fail-safe function, the hydraulic unit cannot be forcibly activated.
  6. Remove the cap on the left of bleeder screw on the torque transfer mechanism, and connect the vinyl hose.
  7. Gradually rotate the steering wheel at the straight-ahead position clockwise. Loosen the left side bleeder screw, and check that the air is bled with fluid.

    CAUTION:
    • Keep the fluid level above the oil filter while air-bleeding. If you fail to do so, an "air layer" will be present below the oil filter. This can cause the fluid not to be added below the oil filter.
    • If the fluid level should have decreased below the oil filter, squeeze and release the feed hose so that the fluid should be added below the oil filter.
  8. After the air bleeding, tighten the bleeder screw and set the steering wheel at the straight-ahead position.

  9. Repeat Steps  6 and  7 for 2 or 3 times. After no air mixture is confirmed, tighten the bleeder screw to the specified torque.

    Tightening torque: 9.0 ± 1.0 N.m (80 ± 9 in-lb) 

  10. Perform Steps  5 to  8 for the right bleeder screw. Note to turn the steering wheel counterclockwise.
  11. When the hydraulic unit is removed, perform air bleeding on the ACD side. (Refer to ON-VEHICLE SERVICE .)
    CAUTION: If the air bleeding is insufficient, the noise from the hydraulic unit occurs, which may deteriorate the pump durability.
  12. After the air bleeding, check the fluid level. (Refer to FLUID LEVEL CHECK  .)
