differential thoroughly with solvent or brake
cleaner, and dry with compressed air.
NOTE: Do not wash the rubber parts with solvent.
6. Insert the inboard end (A) of the driveshaft into the differential (B) or the intermediate shaft (C) until the
set ring (D) locks in the groove (E).
NOTE: Insert the driveshaft horizontally to prevent
damaging the oil seal. 7. Install the outboard joint (A) into the front hub (B).
8. Connect the knuckle (A) onto the lower arm (B).
During installation, install a new flange bolt and
new self-locking nuts. After lightly tightening all

1. Install the steering column in the reverse order of
removal, and note these items:
 Make sure the wires are not caught or pinched by any parts.
 Tighten the three screws (A) in the sequence shown. 2. Center the steering rack within its stroke in the
steering joint connection.
3. With the rack in the straight ahead driving position, cut the wire (A) and slip the lower end of the
steering joint onto the pinion shaft (B).
NOTE: Pinion shaft with center guide; install the steering joint by aligning the center guide.
 Pinion shaft without center guide; position the steering column by aligning the gap (C) with the
angle.
4. Align the bolt hole (A) on the steering joint with the groove (B) around the pinion shaft, then loosely
install the steering joint bolt (C). Be sure that the
joint bolt is securely in the groove in the pinion
shaft. Pull on the steering joint to make sure that
the steering joint is fully seated. Tighten the
steering joint bolt to the specified torque.

3. Remove the old sealant from the rack guide screw (A), and apply new sealant (Three Bond 1215 or
Loctite 5699) to the middle of the threads (B).
Loosely install the rack guide screw on the steering
gearbox.

applying the sealant, remove the old sealant and
residue, and reapply new sealant. 4. Tighten the rack guide screw (A) to 25 N·m
(2.5 kgf·m, 18 lbf·ft), then loosen it.
5. Retighten the rack guide screw to 3.9 N·m (0.4 kgf·m, 2.9 lbf·ft), then back it off to the specified
angle.
6. Hold the rack guide screw stationary with a wrench, and tighten the locknut (B) by hand until it’s fully

7. Install the locknut wrench on the locknut, and hold the rack guide screw stationary with a wrench.
Tighten the locknut to the specified torque.
8. Check for unusual steering effort through the complete turning range.
9. Check the steering wheel rotational play (see page 17-4) and the power assist (see page 17-4).

1. Before installing the steering wheel, make sure the front wheels are aligned straight ahead, then center
the cable reel (A). Do this by first rotating the cable
reel clockwise until it stops. Then rotate it
counterclockwise about three full turns. The arrow
mark (B) on the cable reel label should point
straight up.
2. Position the two tabs (A) of the turn signal canceling sleeve (B) as shown. Install the steering
wheel on to the steering column shaft, making sure
the steering wheel hub (C) engages the pins (D) of
the cable reel and tabs of the turn signal canceling
sleeve. Do not tap on the steering wheel or steering
column shaft when installing the steering wheel. 3. Install the steering wheel bolt (A), and tighten it to
the specified torque. Connect the cable reel
subharness connector (B). Make sure the wire
harness is routed and fastened properly.
4. Install the driver’s airbag, and confirm that the system is operating properly (see page 24-188).
5. Do the battery terminal reconnection procedure (see page 22-68), and do these tasks:
 Turn the ignition switch to ON (II), and check that the SRS indicator comes on for about 6 seconds
and then goes off.
 Make sure the horn and turn signal switches work properly.
 Make sure the steering wheel is centered.
6. After installation, check the steering wheel spoke angle. If the steering spoke angles to the right and
left are not equal (steering wheel is not centered),
correct the engagement of the wheel/column shaft
serrations.

Restriction on Power Assist Operation
Torque Sensor Neutral PositionHow to Troubleshoot DTCs
17-20EPS Components
General Troubleshooting Information (cont’d)
Repeated extreme steering force, such as turning the
steering wheel continuously back-and-forth with the
vehicle stopped, causes an increase of power
consumption in the EPS motor. The increase of electric
current causes the EPS motor to heat up. Because this
heat adversely affects the system, the control unit
monitors the electric current of the EPS motor.
When the control unit detects heat build-up in the EPS
motor, it reduces the electric current to the EPS motor
gradually to protect the system, and it restricts the
power assist operation. The EPS indicator does not
come on during this function.
When steering torque is not applied to the steering
wheel, or when the ignition is turned to LOCK (0) and
the EPS motor cools, the control unit will restore the
power assist gradually until it’s fully restored (after
about 8 minutes).
The EPS control unit stores the torque sensor neutral
position in the EEPROM. The torque sensor neutral
position must be memorized whenever the gearbox, the
EPS motor, or the EPS control unit is replaced.
NOTE: The torque sensor neutral position is not
effected when erasing the DTCs.
The troubleshooting procedures assume that the cause
of the problem is still present and the EPS indicator is
still on. Following the procedure when the EPS
indicator does not come on can result in incorrect
diagnosis.
1. Question the client about the conditions when the problem occurred, and try to reproduce the same
conditions for troubleshooting. Find out when the
EPS indicator came on, such as while turning, after
turning, when the vehicle was at a certain speed,
etc.
2. When the EPS indicator does not come on during the test-drive, but troubleshooting is done based on
the DTC, check for loose connectors, poor terminal
contact, etc., in the affected circuit before you start
troubleshooting.
3. After troubleshooting, clear the DTC and test-drive the vehicle. Be sure the EPS indicator does not
come on.

17-22EPS Components
Memorizing the Torque Sensor Neutral Position
A
The torque sensor neutral position must be memorized
whenever the steering gearbox, the torque sensor, the
EPS motor, or the EPS control unit is replaced. Note that
the torque sensor neutral position is not affected when
erasing the DTC.
NOTE: The torque sensor is temperature sensitive.
When memorizing the torque sensor neutral position,
theambienttemperaturemustbeabove20 10°C
(68 18 °F)
1. With the ignition switch in LOCK (0), connect the HDS to the data link connector (DLC) (A) located
under the driver’s side of the dashboard.
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the EPS control unit. If it doesn’t, troubleshoot
the DLC circuit (see page 11-204).
4. From the EPS MENU, select MISCELLANEOUS TEST, then TORQUE SENSOR LEARN, and follow
the screen prompts on the HDS.
NOTE: See the HDS Help menu for specific
instructions.
5. Turn the ignition switch to LOCK (0).
