SPEEDOMETER INSPECTION
ON±VEHICLE
Using a speedometer tester, inspect the speedometer for al-
lowable indication error and check the operation of the odom-
eter.
HINT: Tire wear and tire over or under inflation will increase
the indication error.
If error is excessive, replace the speedometer.

VEHICLE SPEED SENSOR INSPECTION
INSPECT SENSOR OPERATION
(a) Connect the positive (+) lead from battery to terminal 1 and
negative (±) lead to terminal 2.
(b) Connect the positive (+) lead from tester to terminal 3 and
negative (±) lead to terminal 2.
(c) Rotate shaft.
(d) Check that there is voltage change from approx. 0 V to 11 V
or more between terminals 2 and 3.
HINT: The voltage change should be 4 times for every revolu-
tion of the speed sensor shaft.
If operation is not as specified, replace the sensor. BE±46

PRECAUTION
wCare must be taken to replace parts properly because they could affect the
performance of the steering system and result in a driving hazard.
wThe steering wheel pad has an SRS (Supplemental Restraint System) airbag built in,
so take all due precautions when handling it. For more details, see the RS section.

GENERAL INSPECTION
1. INSPECT TIRE
(a) Check the tires for wear and for the proper inflation pressure.
Cold tire inflation pressure (2JZ±GE)

 255/40ZR17 ±± 250 (2.5, 36)
(b) Check the tire runout.
Tire runout:
Less than 1.4 mm (0.055 in.)
2. INSPECT WHEEL BALANCE
(a) Check and adjust the Off±the±car balance.
(b) If necessary, check and adjust the On±the±car balance.
Unbalance after adjustment:
5.0 g (0.011 lb) or less
3. CHECK WHEEL BEARING LOOSENESS
(a) Check the backlash in bearing shaft direction.
Maximum: 0.05 mm (0.0020 in.)
(b) Check the axle hub deviation.
Maximum: 0.05 mm (0.0020 in.)
4. CHECK FRONT SUSPENSION FOR LOOSENESS
5. CHECK STEERING LINKAGE FOR LOOSENESS
6. CHECK BALL JOINT FOR LOOSENESS
7. CHECK SHOCK ABSORBER WORK PROPERLY
wCheck for oil leak
wCheck mounting bushings for wear
