Service Notice and Precautions for Direct Adaptive Steering

Set the vehicle to the straight-ahead position when checking direct adaptive steering and removing each component.
Check the following items when performing the trouble diagnosis:
- Check if air pressure and size of tires are proper and the specified part used for the steering wheel is genuine part.
- Check if the connection of steering column assembly and steering gear assembly is proper (there is not looseness of mounting bolts, damage of rods, and boots or sealants, etc.).
- Check if the wheel alignment is adjusted properly.
- Check if there is any damage or modification to suspension or body resulting in increased weight or altered ground clearance.
- Check if installation conditions of each link and suspension are proper.
- Check if the battery voltage is proper.
- Check if connection conditions of each connector are proper.
A machine sound may be heard near the driver's seat when the system is starting. This is an operating sound in normal condition of system and the sound is not a malfunction.
Before connecting or disconnecting each component harness connector, turn ignition switch OFF and disconnect battery ground cable, because battery voltage is applied to power steering control module even if ignition switch is turned OFF.
When removing the 12V battery negative terminal, initialization is required for operating the direct adaptive steering normally. Refer to Description .
Refer to Special Repair Requirement for the replacement of each component.
