Steering Wheel And Column Removal/Installation [With Electric Tilt Telescopic Unit]: Notes

D-code 

WARNING:
  • If the steering mechanism is turned from lock to lock continuously or the steering rack terminal limit is reached repeatedly, such high-load steering action increases the temperature of the steering column (to approx.85°C {185°F}), causing severe burns. Be careful when handling the steering column.
CAUTION:
  • If the intermediate shaft is connected to the steering gear (pinion) before installing the steering column to the dashboard member, the weight of the steering column could cause damage to the intermediate shaft slider/bush/yoke. Always perform the procedure according to the appropriate troubleshooting information .
  • A new steering column is shipped with it set to the position for delivery. Maintain this condition until the steering column is completely installed to the dashboard member so as to avoid damage during transportation and installation.
  • When removing/installing the steering column, keep the wiring harness away from the steering column installation area so as to prevent the steering column from being caught in the wiring harness and damaged.
NOTE:
  • When installing the replacement part, do not rotate the steering shaft until the installation is completed.
