4. INSPECT WHEEL BALANCE (for Non-steel Wheel)
(a) Check and adjust the off-the-car balance.
Imbalance after adjustment:
8.0 g (0.018 lb.) or less.
NOTICE:
• Use a cleaning detergent to remove dirt, oil
and water from the surface where the balance
weight is to be adhered.
• Do not touch the sticking surface of the tape.
• Adhere the sticking type balance weight to
the flat position shown in the illustration.
• Push the balance weight securely with a
finger to adhere it to the position.
• Do not reuse the balance weight.
HINT:
• The inner side balance weight should be installed
by clipping it to the rim.
• If necessary, check and adjust the on-the-car
balance.

TEST MODE PROCEDURE
1. SPEED SENSOR SIGNAL CHECK (WHEN USING SST
CHECK WIRE):
HINT:
• If the ignition switch is turned from the ON to the ACC
or LOCK position during Test Mode, the DTCs of the
signal check function will be erased.
(a) Turn the ignition switch off.
(b) Check that the steering wheel is in the straight-
ahead position and move the shift lever to the P
position (Automatic Transmission) or apply the
parking brake (Manual Transmission).
(c) Using SST, connect terminals TS and CG of the
DLC3.
SST 09843-18040
(d) Turn the ignition switch to the ON position.
(e) Check that the ABS warning light is blinking in the
Test Mode.
HINT:
If the ABS warning light does not blink, inspect the
TS and CG terminal circuit and the ABS warning
light circuit.
(f) Start the engine.
(g) Using SST, perform the speed sensor signal check
in Test Mode.
SST 09843-18040
(h) Drive the vehicle straight forward.
(i) Accelerate the vehicle to a speed of 28 mph (45 km/
h) or higher for several seconds and check that the
ABS warning light goes off.
HINT:
The signal check may not be completed if the
vehicle has its wheels spun.
(j) Stop the vehicle.
NOTICE:
• The speed sensor signal check may not be
completed if the steering wheel is turned or
the wheels are spun during the check.

HINT:
The codes in this table are output only in Test Mode
(signal check).
4. SPEED SENSOR SIGNAL CHECK (WHEN USING
INTELLIGENT TESTER):
HINT:
• If the ignition switch is turned from the ON to the ACC
or LOCK position during Test Mode, DTCs of the
signal check function will be erased.
• During Test Mode, the ECU records all DTCs of the
signal check function. By performing the signal check,
the codes are erased if normality is confirmed. The
remaining codes are the codes where an abnormality
was found.
(a) Turn the ignition switch off.
(b) Check that the steering wheel is in the straight-
ahead position.
(c) Connect the intelligent tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Set the intelligent tester to Test Mode (select
"SIGNAL CHECK").
HINT:
Refer to the intelligent tester operator's manual for
further details.

REPAIR
1. STEERING OFF CENTER REPAIR PROCEDURE
(a) Inspect steering wheel off center.
(1) Apply masking tape to the top center of the
steering wheel and steering column upper
cover.
(2) Drive the vehicle in a straight line for 100
meters at a constant speed of 35 mph (56 km/
h), and hold the steering wheel to maintain the
course.
(3) Draw a line on the masking tape as shown in
the illustration.
(4) Turn the steering wheel to its straight position.
HINT:
Refer to the upper surface of the steering
wheel, steering spoke and SRS airbag line for
the straight position.
(5) Draw a new line on the masking tape or the
steering wheel as shown in the illustration.
(6) Measure the distance between the 2 lines on
the masking tape of the steering wheel.
(7) Convert the measured distance to steering
angle.
HINT:
• Measured distance 1 mm (0.04 in.) =
Steering angle approximately 1 deg.
• Make a note of the steering angle.
