CONSULT-II REFERENCE VALUE IN DATA MONITOR MODE
Data are reference value.
* : Almost in accordance with the value of “MOTOR SIG”. It is not a malfunction though these values are not accorded when steering
quickly.
EPS CONTROL UNIT TERMINALS AND REFERENCE VALUE
Data are reference value and are measured between each terminal and ground.
CAUTION:
When using a circuit tester to measure voltage for inspection, be sure not to extend forcibly any connector terminals.
DIAGNOSTIC PROCEDURE
1. CHECK EPS MOTOR SIGNAL
With CONSULT-II
1. Start engine.
2. Select “DATA MONITOR” mode for “EPS” with CONSULT-II.
3. Check the values of “MOTOR SIG” and “MOTOR CURRENT”. Refer to STC-11, "
SPECIFICATIONS
WITH CONSULT-II" .
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2. CHECK EPS MOTOR
1. Turn ignition switch “OFF”.
2. Disconnect EPS control unit harness connector.
3. Check resistance between EPS control unit harness connector
(A) terminals.
4. Connect EPS control unit harness connector.
OK or NG
OK >> GO TO 3.
NG >> EPS motor is malfunctioning. Replace steering column
assembly. Refer to PS-9, "
Removal and Installation" .

InspectionEES002D7
ALUMINUM WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel
runout.
a. Remove tire from aluminum wheel and mount on a tire balance machine.
b. Set dial indicator as shown.
STEEL WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel
runout.
a. Remove tire from steel wheel and mount on a tire balance machine.
b. Set two dial indicators as shown.
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around
the circumference of the wheel.
e. Calculate runout at each point as shown.
f. Select maximum positive runout value and the maximum nega-
tive value.
Add the two values to determine total runout. In case a positive
or negative value is not available, use the maximum value (neg-
ative or positive) for total runout. If the total runout value
exceeds the limit, replace steel wheel.Wheel runout
(Dial indicator value): Refer to WT-29, "
Road Wheel" .
SFA975B
Radial runout = (A+B)/2
Lateral runout = (C+D)/2
Wheel runout : Refer to WT-29, "

Balancing WheelsEES002D8
Adjust wheel balance using road wheel center.
CAUTION:

Be careful not to scratch the road wheel during removal.

Use clip-on type wheel balance weights only.
Wheel balance (Maximum allowable unbalance):
RotationEES002D9

Follow the maintenance schedule for tire rotation service inter-
vals. Refer to MA-7, "
PERIODIC MAINTENANCE" .

Do not include the T-type spare tire when rotating tires.
CAUTION:

When installing wheels, tighten them diagonally by divid-
ing the work two to three times in order to prevent the
wheels from developing any distortion.

Be careful not to tighten wheel nut at torque exceeding
the specification to prevent damage of disc rotor.
Maximum allowable unbalanceDynamic (At rim flange) Less than 5 g (0.18 oz) (one side)
Static (At rim flange) Less than 10 g (0.35 oz)
