Replacement part

Warning

• Handling the driver-side air bag module improperly can accidentally operate (deploy) the air bag module, which may seriously injure you. Read the air bag system service warnings and cautions before handling the driver-side air bag module. (See AIR BAG SYSTEM SERVICE WARNINGS [STANDARD DEPLOYMENT CONTROL SYSTEM – MEXICO SPEC.].) (See AIR BAG SYSTEM SERVICE CAUTIONS [STANDARD DEPLOYMENT CONTROL SYSTEM – MEXICO SPEC.].) (See AIR BAG SYSTEM SERVICE WARNINGS [TWO-STEP DEPLOYMENT CONTROL SYSTEM – US/CANADA SPEC.].) (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 a steering column which has been received an impact.

Caution

• When replacing the EPS CM, perform the configuration to assure that the system operates correctly. (See CONFIGURATION.)

• 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 EPS CM receives an impact, replace it.

• 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.

• Because the weight of the steering column is approx. 10 kg {22 lb}, it may fall off during servicing and be damaged. Be careful when handling the steering column.

• 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 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).

• When handling the steering column, do not release the adjuster lever lock except when the steering column is securely assembled to the dashboard member. Otherwise, it could damage the steering column and the other parts.

• 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

• 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 the replacement part, do not rotate the steering shaft until the installation is completed.

• In order to completely interrupt the EPS system power supply, do not disconnect the battery within 60 s 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.
