Disconnect both battery cables The steering lock will remain released with both battery cables disconnected and the steering wheel can be turned Perform the necessary repair operation Revision: 2012 July ST-2 N17 PRECAUTIONS < PRECAUTION > When the repair work is completed, re-connect both battery cables With the brake pedal released, turn the ignition switch from ACC position to ON position, then to LOCK position (The steering wheel will lock when the ignition switch is turned to LOCK position.) Perform self-diagnosis check of all control units using CONSULT A Service Notice or Precautions for Steering System B INFOID:0000000006654080 • In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehicle condition, and then check wheel alignment • Observe the following precautions when disassembling - Before disassembly, thoroughly clean the outside of the unit - Disassembly should be done in a clean work area It is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter - For easier and proper assembly, place disassembled parts in order on a parts rack - Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere with their operation - Never reuse non-reusable parts - Before assembling, apply the specified grease to the directed parts C D E F ST H I J K L M N O P Revision: 2012 July ST-3 N17 PREPARATION < PREPARATION > PREPARATION PREPARATION
