TROUBLE DIAGNOSIS
Actuator operation check
1. Connect 9 and 10 terminals of actuator to 40 and 41 terminals of
relay box.
2. Measure the motor voltage (No.4 terminal to body earth) with
oscilloscope. Then check the motor reverse voltage occasioned
time.
The motor reverse voltage occasioned time is more than 0.1
sec.
CAUTION:
●Perform checking of motor relay unit. Then confirm that
relay functions.
●Driving actuator motor is with in 4 sec. to prevent heating
up.
●Standard condition of the motor reverse voltage occa-
sioned time is: Battery voltage is 12V. Temperature 20°.
when the battery voltage or temperature is lower than the
standard, the motor reverse voltage occasioned time
becomes slightly shorter.

On-Vehicle Inspection and ServiceEGS0004E
PLAY INSPECTION
1. Turn steering wheel to straight-ahead position. Start engine and lightly turn steering wheel clockwise and
counter clockwise until front wheels start moving. Measure travel to starting point on circumference of
steering wheel.
2. If play is outside specifications, check following parts for proper installation: steering gear assembly, front
suspension, axles, and steering column
●Check steering wheel for vertical, horizontal, or axial play.
●Lift vehicle and check steering gear mounting bolts and nuts for looseness.
NEUTRAL POSITION INSPECTION
●After the wheel alignment inspection, carry out the neutral position inspection. Refer to FSU-6, "Wheel
Alignment" .
●Before removing steering wheel, check steering gear neutral position.
1. Set vehicle to straight-ahead position, and check that steering wheel is in neutral position.
2. If it is not in neutral position, remove steering wheel, and install again in properly.
3. If it is not adjusted within two teeth from center of gear, loosen tie rod lock nut. Then turn it to opposite
direction to adjust until amount of left and right becomes equal.
STEERING TORQUE CHECK
1. Stop vehicle on a dry flat paved road and apply parking brake.
2. Start engine and wait until power steering fluid warms up. Using
a preload gauge, check rotational torque of steering wheel.
3. If torque is outside specifications, check rack sliding torque and
oil pump relief pressure.
STEERING ANGLE INSPECTION
●After toe-in inspection, check steering angle. Place front wheels
on turning radius gauges and rear wheels on stands. Level the
vehicle. Check maximum inner and outer wheel steering angles
for LH and RH road wheels.Steering wheel play inspection standard : 0 - 35 mm (0 - 1.38 in)
Steering wheel axial endplay : 0 mm (0 in)
Tightening torque : 140 - 160 N·m (14.2 - 16.4 kg-m, 103 - 118 ft-lb)
Steering torque:
706 N·cm (72 kg-cm, 62 in-lb) or less
Rack sliding torque:
153 - 240 N (15.5 - 24.5 kg, 34.3 - 54.2 lb)
Oil pump relief hydraulic pressure:
8,140 - 8,728 kPa (81.4 - 87.3 bar, 83 - 89 kg/cm
