Steering Column: Service and Repair
Removal and InstallationPS-9 Component:
CAUTION:
^ Do not allow axial impact to steering column assembly during removal and installation.
^ Steering column must be kept at maximum tilt up position during removal and installation. Do not operate tilt mechanism while steering column is out of the vehicle.
^ Put matching mark on intermediate shaft and steering column assembly before removing intermediate shaft.
^ When steering wheel is turned repeatedly with the vehicle stopped, care must be taken because motor and EPS control unit may get too hot.
^ Steering column assembly is heavy. Care must be taken when removing steering column assembly from vehicle.
^ Do not put steering column assembly near the things that generate excessive magnetic force.
^ Steering column assembly (with motor, reduction gear, sensor) cannot be disassembled.
REMOVAL
1. Set front wheels to straight ahead-position.
2. Remove driver air bag module.
3. Remove steering wheel.
4. Remove steering column cover (upper and lower).
5. Remove combination switch and spiral cable.
6. Remove instrument lower finisher.
7. Disconnect each switch connector installed to steering column assembly, and then disconnect harness from steering column assembly.
8. Remove bolt of intermediate shaft (upper side), and then remove intermediate shaft from steering column assembly.
9. Remove steering column assembly mounting nuts, and then remove steering column assembly from vehicle.
10. Remove bolt of intermediate shaft (lower side), and then remove intermediate shaft from vehicle.
11. Remove screws of bracket and EPS control unit, and then remove bracket and EPS control unit from steering column assembly.
INSPECTION AFTER REMOVAL
^ Check each part of steering column assembly, EPS control unit and intermediate shaft for damage and. replace as necessary.
^ Measure the length "L" as shown, if vehicle has been involved in a minor collision. Replace steering column assembly (with motor, reduction gear, sensor) if outside the standard.
^ Check tilt mechanism for damage or other malfunctions. Replace steering column assembly (with motor, reduction gear, sensor) as necessary.
^ Measure steering column assembly rotating torque using Tool. Replace steering column assembly (with motor, reduction gear, sensor) if outside the standard.
Tool number ST3127S000 (J-25742-1)
Rotating torque: 0 - 2.1 Nm (0 - 0.21 kg-m, 0 - 18 in-lb)
INSTALLATION
Installation is in the reverse order of removal.
^ Installation is in the reverse order of removal. For tightening torque, refer to "COMPONENT".
^ When tightening bolt (intermediate shaft lower side), tighten it by hand first, and make sure there is no feeling of sticking or galling before final tightening.
CAUTION: Insert bolt in the proper direction. (Do not insert it from the other side.)
^ When connecting intermediate shaft upper side (1) and column shaft, make sure the bolt is securely seated in groove (A) of column shaft (A) before final tightening.
INSPECTION AFTER INSTALLATION
^ Rotate steering wheel to check for decentered condition, binding, noise or excessive steering effort.
^ After installing steering column assembly, perform self-diagnosis with CONSULT-II to ensure correct operation. Refer to STC-11, "CONSULT-III Function (EPS)". Consult-III Function (EPS)
^ Check tilt mechanism operating range "L" as shown.
Tilt operating range "L": 20 mm (0.79 in)
