1. Do the battery terminal disconnection procedure (see page 22-68).
2. Remove the passenger’s dashboard lower cover (see page 20-102).
3. Remove the passenger’s side kick panel (see page 20-66).
4. Disconnect EPS control unit connectors A (2P), connector B (2P), connector C (2P), and connector D
(28P).
5. Remove the nuts (E) from the EPS control unit (F).
6. Remove the EPS control unit. 7. Install the EPS control unit in the reverse order of
removal.
8. Do the battery terminal reconnection procedure (see page 22-68), and do these tasks:
 Make sure the horn and turn signal switches work properly.
 Make sure the steering wheel switches work properly.
 If the EPS control unit is replaced, the EPS control unit must memorize the torque sensor neutral
position (see page 17-22).
9. After installation, start the engine, and let it idle. Turn the steering wheel from lock-to-lock several
times. Check that the EPS indicator does not come
on.

Use commercially available computerized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
equipment manufacturer’s instructions.1. Check the camber angle. NOTE: There are two types of rear upper arms. Those that are marked with ‘‘C’’ (A), and those with no
marks. Be sure to use the correct alignment
specifications.
 If the measurement is within specification, measure the toe-in.
 If the measurement for the front camber is outside the specification, go to front camber
adjustment.
 If the measurement for the rear camber is outside the specification, check for bent or damaged
suspension components. The front camber can be adjusted by exchanging one or
both of the damper pinch bolts with a smaller diameter
adjusting bolt. The difference between the adjusting
bolt diameter and the pinch bolt hole diameter allows
for a small range of adjustment.
1. Raise the front of the vehicle, and support it with safety stands in the proper locations (see page
1-11).
2. Remove the front wheels.
3. Loosen the damper pinch bolts (A), and adjust the camber angle by moving the bottom of the damper
within the range of the damper pinch bolt free play.
4. Tighten the damper pinch bolts to the specified torque.
5. Clean the mating surfaces of the brake disc and the inside of the wheel, then install the front wheels.
6. Lower the vehicle to the ground, and bounce the front of the vehicle up and down several times to
stabilize the suspension.
Replace.

7. Measure the camber angle.
 If the measurement is within specification,measure the toe.
 If the measurement is not within specification, go to step 8.
8. Raise the front of the vehicle, and support it with safety stands in the proper locations (see page
1-11).
9. Remove the front wheels.
10. Replace the damper pinch bolts with the adjusting bolts (A), and adjust the camber angle.
NOTE: Install the washers (B) included adjusting bolt set between the front damper and self-locking nut.
 The camber angle can be adjusted up to 25 ’ (center of tolerance) by replacing one damper
pinch bolt with the adjusting bolt.
 The camber angle can be adjusted up to 50 ’ by replacing both damper pinch bolts with the
adjusting bolts.
11. Tighten the adjusting bolts to the specified torque value.
12. Clean the mating surfaces of the brake disc and the inside of the wheel, then install the front wheels.
13. Lower the vehicle to the ground, and bounce the front of the vehicle up and down several times to
stabilize the suspension.
14. Measure the camber angle. If the camber angle is not within specification, repeat steps 8 through 13
to readjust the camber angle. If the camber
measurement is correct, measure toe-in, and adjust
it if necessary. Use commercially available computerized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
equipment manufacturer’s instructions.
1. Set the steering column to the middle tilt and center telescopic positions. Center the steering
wheel spokes, and install a steering wheel holder
tool.
2. Check the toe with the wheels pointed straight ahead.
 If adjustment is required, go to step 3.
 If no adjustment is required, go to rear toe inspection/adjustment.
3. Loosen the tie-rod locknuts (A) while holding the flat surface sections (B) of the tie-rod end with a
wrench, and turn both tie-rods (C) until the front toe
is within specifications.
4. After adjusting, tighten the tie-rod locknuts to the specified torque value. Reposition the rack-end
boot if it is twisted or displaced.
5. Go to rear toe inspection/adjustment.

Use commercially available computerized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
equipment manufacturer’s instructions.
1. Release the parking brake to avoid an incorrect measurement.
2. Check the toe.
 If adjustment is required, go to step 3.
 If no adjustment is required, go to turning angleinspection.
3. Hold the adjusting bolt (A) on the trailing arm (B), and loosen the self-locking nut (C).
4. Replace the self-locking nut with a new one, and lightly tighten it.
NOTE: Always use a new self-locking nut whenever it has been tightened to the specified torque.
 Reassemble the adjusting bolt and the adjusting cam plate with the eccentric facing up.
5. Adjust the rear toe by turning the adjusting bolt until the toe is correct.
6. Tighten the self-locking nut to the specified torque value while holding the adjusting bolt. Use commercially available computerized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
equipment manufacturer’s instructions.
1. Turn the wheel right and left while applying the brake, and measure the turning angle of both
wheels.
2. If the measurement is not within the specifications, even up both sides of the tie-rod threaded section
length while adjusting the front toe. If it is correct,
but the turning angle is not within the
specifications, check for bent or damaged
suspension components.
