COMPONENT











CAUTION:
- Do not allow axial impact to steering column assembly during removal and installation.

- 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.
- Any time the ignition switch has been removed and installed, the keys must be re-registered in the
BCM. Refer to CONSULT�III operation manual IVIS/NVIS.

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.

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 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-III to ensure correct operation. Scan Tool Testing and Procedures.





- Check tilt mechanism operating range "L" as shown.

Tilt operating range "L" : 20 mm (0.79 in)
