   NOTE:

   First wipe off the existing grease from the serrated part, and then apply the dedicated grease supplied with a new power steering motor assembly or electric power steering column sub-assembly.

2. Temporarily install the power steering motor assembly to the electric power steering column sub-assembly with the 2 bolts.
   NOTE:

   When temporarily installing the 2 bolts to the power steering motor assembly, do not tighten them all the way down.

3. Secure the steering column assembly in a vise using aluminum plates.

   *1	Aluminum Plate
   *2	Wooden Block

   NOTE:

   • Do not overtighten the vise, as the steering column assembly may become deformed.
   • Secure the power steering motor assembly so that it is directly upright.
   • Support the steering column assembly with a wooden block or similar item to ensure that it does not fall.
4. Using SST, turn the steering main shaft once 180 degrees to the left and then 180 degrees to the right at a speed of 60 rpm, and repeat 2 to 3 times to adjust the axis centering of the power steering motor assembly.
   • SST: 09616-00011

   Turning torque 

   Torque: 1.4 N*m (14 kgf*cm, 12 in.*lbf) 

   or less

   NOTE:

   Ensure that there is no abnormal resistance during rotation.

   If the torque is not as specified, readjust the axis centering of the power steering motor assembly.

7. Install a new clamp and tape to the wire harness as shown in the illustration.

   *3	Tape A	*4	Clamp
   *5	Tape B	-	-
   *a	383 to 403 mm (1.26 to 1.32 ft.)	*b	100 mm (3.934 in.)
   *c	80 to 100 mm (3.15 to 3.93 in.)	*d	155 to 175 mm (6.11 to 6.89 in.)
   *e	74 to 94 mm (2.92 to 3.70 in.)	*f	10 mm (0.394 in.)

   NOTE:

   • Wrap the tape around the area marked as "A" in the illustration more than 1.5 times.
   • Wrap the tape around the area marked as "B" in the illustration more than 2 times.
   • As heat from the power steering motor assembly may generate smoke, use heat resistant tape (resistant to 100°C (212°F) or more).
8. Cut off the excess length of the clamp.

1. Engage the 2 claws to install the ignition or starter switch assembly onto the upper steering column bracket assembly.

1. Install the key inter lock solenoid onto the upper steering column bracket assembly with the screw.

1. Engage the 2 claws to install the un-lock warning switch assembly onto the upper steering column bracket assembly.

   HINT: 

   Slide the un-lock warning switch assembly, in the direction shown by the arrow in the illustration, to install it.

1. Turn the ignition switch to ACC.
