AYC Bleeding
WARNING: This page is about a different car, the 2008 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.
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)}.
- Lift up the vehicle.CAUTION: Turn the ignition switch to the "LOCK (OFF)" position before connecting or disconnecting the scan tool.
- Set the scan tool to the 16-pin data link connector. (Refer to HOW TO CONNECT THE SCAN TOOL (M.U.T.-III) .)
- Turn the ignition switch to the "ON" position.
- Set the steering wheel in the straight-ahead position.
- 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.
- Remove the cap on the left of bleeder screw on the torque transfer mechanism, and connect the vinyl hose.
- 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:
- During the air bleeding, fill the fluid so that the fluid constantly remains in the oil reservoir.
- When the oil is filled into the empty oil reservoir, check that the oil is filled up under the filter inside the oil reservoir.
- After the air bleeding, tighten the bleeder screw and set the steering wheel at the straight-ahead position.
- 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)
- Perform Steps 5 to 8 for the right bleeder screw. Note to turn the steering wheel counterclockwise.
- 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.
- After the air bleeding, check the fluid level. (Refer to GEAR OIL REPLACEMENT .)
