STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION
id061300801400
-
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.
• If the steering column is dropped, the EPS CM could be damaged internally causing the steering mechanism to become inoperative, which could result in an unexpected accident. Always replace the steering column if it has been subjected to an impact.
-
Caution
-
• The EPS CM will not operate normally if the EPS configuration is not performed. If the steering column is replaced, always perform the EPS CM auto configuration so that the EPS operates normally.
• If the steering column is dropped it could result in internal damage to the EPS CM, therefore be careful not to drop it. If the steering column receives an impact, replace the steering column.
• If the steering column is stored in a humid place, the EPS system may not operate properly when installed to the vehicle. Store the steering column in a suitable place.
• Be careful when handling the steering column because it weighs approximately 10 kg {22 lb} and it could fall off and be damaged while servicing.
• 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 follow the procedure in the Workshop Manual.
• The universal joint could be damaged if subjected to an impact when the intermediate shaft (pinion) is disconnected. Perform the servicing carefully avoiding impact when disconnecting the intermediate shaft from the steering gear (pinion).
• Do not release the lock of the adjusting lever when handling the steering column unless it is securely installed to the dashboard member. If the adjusting lever is unlocked with the steering column not securely installed, the steering column and other parts could be damaged.
• A new steering column is shipped in a pre-set condition. 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
-
• The EPS CM prior to replacement stores the vehicle specification information.
• A new EPS CM does not store any vehicle specification information.
• When the ignition is switched ON (engine off or on) after the EPS CM is replaced, the EPS CM reads the vehicle specification information sent via CAN communication from the instrument cluster and stores it.
• If the vehicle is driven in a straight line at a vehicle speed of approx. 10 km/h {6.2 mph} or more, the EPS CM detects the steering angle neutral position automatically. Until the self-learning of the steering angle neutral position is finished, the EPS CM performs assist control based on the steering angle recognized when the ignition is switched ON (engine off or on).
• When installing a replacement part, be careful not to rotate the steering shaft until the installation has been completed.
• In order to completely interrupt the EPS system power supply, do not disconnect the battery for 60 s or more after the ignition switch is turned off.
• Do not replace the steering column (EPS system) with that of another vehicle even if they are the same model.
• Before connecting the EPS CM connector, remove the fuse or disconnect the battery to interrupt the power supply completely.
• When removing the driver-side air bag module, it is necessary to rotate the steering wheel.If the ignition has been switched off with the driver's door closed, the steering wheel will be locked.Perform the procedure from Steps 1-3 so that the steering wheel will not be locked.
1. Switch the ignition ON (engine off or on).
