TIRE AND WHEEL SYSTEM

PRECAUTION

1. REMOVAL AND INSTALLATION OF THE TIRE PRESSURE WARNING VALVE SUB-

ASSEMBLY

a. When installing a tire, make sure that the tire pressure warning valve and transmitter does not

interfere with the tire bead in order to prevent damage to the sensor.

b. After completing the installation, remove the valve core to rapidly release the air in the tire and

check that the warning light comes on. If the warning light does not come on, the system may be
defective.

c. If there is an air leakage, tighten the nut to a torque of 4.0 N*m (41 kgf*cm, 35 in.*lbf) and push

the valve core 2 or 3 times to remove any dirt attached to the valve core. If air continues to leak,
replace the grommet, washer and nut. Use a manufacturer-specified cap.

d. When installing the tire pressure warning valve and transmitter, check that the rim, grommet,

washer and nut are clean. Use a manufacturer-specified cap.

e. When inflating the tire, first install the tire pressure valve straight onto the stem of the tire pressure

warning valve and transmitter.

2. TIRE AND WHEEL REPLACEMENT OR TIRE ROTATION

a. If replacing a tire, be sure to check the grommet of the tire pressure warning valve and transmitter

for damage. If the grommet is damaged, replace the grommet, washer, and nut.

b. If tires and wheels are replaced, register the transmitter ID (see REGISTRATION ).

5. INSPECT REAR AXLE SHAFT

a. Inspect the rear axle shaft (see INSPECTION ).

TIRE PRESSURE WARNING SYSTEM

PRECAUTION

1. TIRE PRESSURE WARNING SYSTEM PRECAUTION

a. When the tire pressure warning light turns on, immediately check the tire pressures and adjust them

to the specified value(s).

b. When the tire pressure warning light turns on after blinking for 1 minute, there is a malfunction in

the system. Check for DTCs.

c. It is necessary to register the transmitter ID in the tire pressure warning ECU after replacing the tire

pressure warning valve and transmitter and/or tire pressure warning ECU (See
REGISTRATION ).

d. When replacing the tire pressure warning ECU:

1. Using the Data List, read the transmitter IDs registered in the ECU and make a note of them
