REMOVAL AND INSTALLATION



<LHD>


note ASC-ECU is located in the hydraulic unit.
caution When the hydraulic unit (integrated with ASC-ECU) is replaced, after turning the ignition switch ON or OFF (vehicle information from ETACS-ECU is registered), always carry out the calibration of all sensors (steering wheel sensor, G and yaw rate sensor, and brake fluid pressure sensor) at one time. (Refer to .)
Pre-removal operation
  • Brake fluid draining.
  • Air cleaner assembly removal (Refer to GROUP 15 - Air Cleaner ).
  • Removal of PDU cover and disconnection of the wires attached to PDU (Refer to GROUP 54D - Power drive unit ).
  • Fuel vapour canister removal (Refer to GROUP 17 - Canister ).

Post-installation operation
  • Fuel vapour canister installation (Refer to GROUP 17 - Canister ).
  • Installation of PDU cover and connection of the wires attached to PDU (Refer to GROUP 54D - Power drive unit ).
  • Air cleaner assembly installation (Refer to GROUP 15 - Air Cleaner ).
  • Brake fluid refilling and air bleeding (Refer to GROUP 35A - On-vehicle Service, Bleeding ).
  • Hydraulic unit check (Refer to ).

REMOVAL SERVICE POINTS



<<A>> ASC-ECU HARNESS CONNECTOR DISCONNECTION



Operate the lock lever to disconnect the ASC-ECU harness connector as shown in the figure.

<<B>> HYDRAULIC UNIT (ASC-ECU) REMOVAL


caution
  • Be careful when removing the hydraulic unit because it is heavy.
  • Never loosen the nuts and the bolts because the hydraulic unit cannot be disassembled.
  • Do not drop or shock the hydraulic unit.
  • Do not turn the hydraulic unit upside down or lay down the unit because the inner air becomes difficult to be bled.

INSTALLATION SERVICE POINT
