ROAD WHEEL
InspectionINFOID:0000000001703748
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-25, "
Road Wheel".
SFA975B
Radial runout = (A+B)/2
Lateral runout = (C+D)/2
Wheel runout : Refer to WT-25, "

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.

RotationINFOID:0000000001703750
• Follow the maintenance schedule for tire rotation service intervals.
Refer to MA-6
.
• Do not include the T-type spare tire when rotating tires.
CAUTION:
• When installing wheels, tighten them diagonally by dividing
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)

System DescriptionINFOID:0000000001703752
BODY CONTROL MODULE (BCM)
The BCM is shown with the glove box removed. The BCM reads the
air pressure signal received by the remote keyless entry receiver,
and controls the low tire pressure warning lamp as shown below. It
also has a self-diagnosis function to detect a system malfunction.

< SERVICE INFORMATION >
TIRE PRESSURE MONITORING SYSTEM
A sensor-transmitter integrated with a valve is installed in each
wheel, and transmits a detected air pressure signal in the form of a
radio wave. The radio signal is received by the remote keyless entry
receiver.
REMOTE KEYLESS ENTRY RECEIVER
The remote keyless entry receiver is shown with the glove box
removed. The remote keyless entry receiver receives the air pres-
sure signal transmitted by the transmitter in each wheel.
COMBINATION METER
The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter low tire pressure warn-
ing lamp is activated.

ID Registration ProcedureINFOID:0000000001703756
ID REGISTRATION WITH TRANSMITTER ACTIVATION TOOL
NOTE:
This procedure must be done after replacement of a low tire pressure warning transmitter or BCM.
New replacement transmitters are provided "asleep" and must first be "woken up" using Transmitter
Activation Tool J-45295 before ID registration can be performed.
1. Connect CONSULT-III.
2. Select “AIR PRESSURE MONITOR” on "SELECT TEST ITEM" screen.
3. Select “WORK SUPPORT” on "SELECT DIAG MODE" screen, and select "ID REGIST".
4. Push the transmitter activation tool against the tire near the front
left transmitter. Press the button for 5 seconds.
5. Register the IDs in order from FR LH, FR RH, RR RH and RR LH. When ID registration of each wheel has
been completed, a buzzer sounds and the hazard warning lamps flash.
6. After completing all ID registrations, press “END” to complete the procedure.
NOTE:
Be sure to register the IDs in order from FR LH, FR RH, RR RH, to RR LH, or the self-diagnostic results dis-
play will not function properly.
ID REGISTRATION WITHOUT TRANSMITTER ACTIVATION TOOL
NOTE:
This procedure must be done after replacement of a low tire pressure warning transmitter or BCM.
New replacement transmitters are provided "asleep" and must first be "woken up" using Transmitter
Activation Tool J-45295 before ID registration can be performed.
1. Connect CONSULT-III.
2. Select “AIR PRESSURE MONITOR” on “SELECT TEST ITEM" screen.
3. Select “WORK SUPPORT” on “SELECT DIAG MODE" screen, and select "ID REGIST".
4. Adjust the tire pressure to the values shown in the table below and drive the vehicle at 15 km/h (9.4 MPH)
or more for a few minutes.
5. After completing all ID registrations, press “END” to complete the procedure.Tool number : (J-45295)

Transmitter Wake Up OperationINFOID:0000000001703757
NOTE:
This procedure must be done after replacement of a low tire pressure warning transmitter or BCM.
New replacement transmitters are provided "asleep" and must first be "woken up" using Transmitter
Activation Tool J-45295 before ID registration can be performed.
1. Turn ignition switch ON. Push the transmitter activation tool
against the tire near the front left transmitter. Press the button for
5 seconds. The hazard warning lamps flash per the diagram
below.
2. Repeat this procedure for each tire in the following order: FL, FR, RR, RL.
3. When the BCM finishes assigning each tire ID, the BCM flashes the hazard warning lamps and sends
flashing indicator status by CAN according to the following time chart.
4. After completing wake up of all transmitters, make sure low tire pressure warning lamp goes out.
