Steering Wheel And Column Removal/Installation: Notes
Replacement Part
| Lock Bolt Quantity: 1 Location of use: Steering wheel |
Joint bolt Quantity: 1 Location of use: Intermediate shaft (upper side) |
Joint bolt Quantity: 1 Location of use: Intermediate shaft (lower side) |
WARNING:
- Handling the driver-side air bag module improperly can accidentally deploy the air bag module, which may seriously injure you. Read the air bag system service warnings and cautions before handling the air bag module. (See AIR BAG SYSTEM SERVICE WARNINGS (US/CANADA) .) (See AIR BAG SYSTEM SERVICE CAUTIONS [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] ).
- 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 Control Module 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 Control Module will not operate normally if the EPS configuration is not performed. If the steering column is replaced, always perform the EPS Control Module auto configuration so that the EPS operates normally.
- If the steering column is dropped it could result in internal damage to the EPS Control Module, 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 Service Information.
- 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 Control Module prior to replacement stores the vehicle specification information.
- A new EPS Control Module does not store any vehicle specification information.
- When the ignition is switched ON (engine off or on) after the EPS Control Module is replaced, the EPS Control Module 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 Control Module detects the steering angle neutral position automatically. Until the self-learning of the steering angle neutral position is finished, the EPS Control Module 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 fir 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 Control Module connector, remove the fuse or disconnect the battery to interrupt the power supply completely.
- Disconnect the negative battery terminal and wait for 1 min or more. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION ).
- Remove the driver-side air bag module. (See DRIVER-SIDE AIR BAG MODULE REMOVAL [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] .) (See DRIVER-SIDE AIR BAG MODULE INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.] ).
- Straighten the steering wheel.
- Disconnect the steering switch connector.
- Disconnect the heated steering wheel control unit connector. (With heated steering wheel system)
- Remove the lockbolt.
- Remove the steering wheel.CAUTION:
- Do not try to remove the steering wheel by hitting the shaft with a hammer. The steering column will be damaged.
