REMOVAL AND INSTALLATION


caution
  • Before removing the steering wheel, driver’s air bag module assembly and knee air bag module refer to GROUP 52B - Service Precautions , Driver’s Air Bag Module and Clock Spring and Knee Air Bag Module <Vehicles with knee air bag>.
  • After the installation, perform a calibration for the ASC-ECU to learn the steering wheel sensor neutral point. (Refer to GROUP 35C - On-vehicle Service, Steering Wheel Sensor Calibration ) <Vehicles with ASC>.
  • Do not reuse the part that has been dropped because its internal components may be defective even if it has no apparent damage.
  • Always keep the steering column shaft assembly away from the matter that generates magnetic force.
  • For the steering column shaft assembly, parts cannot be disassembled.
  • Be careful when removing and installing the steering column shaft assembly, because it is heavy.
Pre-removal Operation
  • Steering Wheel Straight-ahead Position Check
  • Steering Wheel Assembly Removal (Refer to ).
  • Knee Air Bag Module Removal (Refer to GROUP 52B - Knee Air Bag Module ) <Vehicles with knee air bag>.

 Post-installation Operation
  • Knee Air Bag Module Installation (Refer to GROUP 52B - Knee Air Bag Module ) <Vehicles with knee air bag>.
  • Steering Wheel Assembly Installation (Refer to ).
  • Steering Wheel Straight-ahead Position Check

 Steering column shaft assembly

REMOVAL SERVICE POINT

<<A>> STEERING COLUMN SHAFT ASSEMBLY REMOVAL
1.Ensure that the tilt lever is in the lock position.
2.Remove the steering column shaft assembly mounting bolt.

caution
  • Hold the motor shown because improper installation may result when the jacket assembly comes off or turns.
  • Do not apply any load to the harness because an open circuit may occur.
  • Do not release the tilt lever because the jacket assembly may come off.
  • Do not subject separation capsule to any shocks because the collision energy absorbing mechanism may not work normally or the steering column shaft may fall down after installing.
3.Remove the steering column shaft assembly.

INSTALLATION SERVICE POINTS

>>A<< STEERING COLUMN SHAFT ASSEMBLY INSTALLATION
1.Ensure that the tilt lever is in the lock position.

caution
  • Hold the motor shown because improper installation may result when the jacket assembly comes off or turns.
  • Do not apply any load to the harness because an open circuit may occur.
  • Do not release the tilt lever until the steering column shaft assembly is installed to the vehicle, because the mounting position to the vehicle may be misaligned or the installation to the vehicle may become difficult.
  • Do not subject the separation capsule to any shocks because the collision energy absorbing mechanism may not work normally or the steering column shaft may fall down after installing.
  • Connect the motor harness to EPS-ECU without excessive bend or twisting.


2.Hand-tighten the mounting bolts in the order of a, b, c, and tighten them in the order of c, b, a to the specified torque.
Tightening torque:

  • Mounting bolt a: 54 ± 11 N·m
  • Mounting bolt b, c: 21 ± 3 N·m

>>B<< STEERING COLUMN BOLT (STEERING COLUMN SHAFT ASSEMBLY AND STEERING GEAR & LINKAGE CONNECTION) INSTALLATION

Insert the steering column bolt into the non-threaded bolt hole, and tighten it to the specified torque.
Tightening torque : 36 ± 6 N·m
