InspectionNES000JO
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 in the figure.
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 in the figure.
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 below.
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 (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel.Wheel runout (Dial indicator value)

c. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other as shown in
the figure.
CAUTION:
Do not install one balance weight sheet on top of another.
3. Start tire balance machine again.
4. Install drive-in balance weight on inner side of road wheel in the
tire balance machine indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start tire balance machine. Make sure that inner and outer resid-
ual unbalance value are 7 g (0.25 oz) each or below.
If either residual unbalance value exceeds 7 g (0.25 oz), repeat installation procedures.
RotationNES000JQ
Follow the maintenance schedule for tire rotation service inter-
vals. Refer to MA-7, "
PERIODIC MAINTENANCE" .
Do not include the 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 criteria for preventing strain of disc rotor.

TROUBLE DIAGNOSES
Revision: 2007 April2007 M35/M45
ID Registration ProcedureNES000JY
ID REGISTRATION WITH ACTIVATION TOOL
This procedure must be done after replacement of a tire pressure transmitter, low tire pressure warn-
ing control unit, or tire rotation.
1. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "
CONSULT-II Start Procedure" .
2. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
3. Touch “ID REGIST” on “SELECT WORK ITEM”.
4. With the activation tool (J-45295) pushed against the front-left
tire pressure transmitter position of the tire air valve, press and
hold the button for 5 seconds.
5. Register the IDs in order from FR LH, FR RH, RR RH, RR LH.
When ID registration of each wheel has been completed, turn
signal lamp blinks.
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-diagnosis results
display will not function properly.
ID REGISTRATION WITHOUT ACTIVATION TOOL
This procedure must be done after replacement of a tire pressure transmitter, low tire pressure warn-
ing control unit, or tire rotation.
1. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "
CONSULT-II Start Procedure" .
2. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
3. Touch “ID REGIST” on “SELECT WORK ITEM”.
4. Adjust the tire pressure to the values shown in the table below for ID registration, and drive the vehicle at
40 km/h (25 MPH) or more for a few minutes.
5. After completing all ID registrations, press “END” to complete the procedure.
6. Inflate all tires to proper pressure. Refer to WT-41, "
SERVICE DATA AND SPECIFICATIONS (SDS)" .

TROUBLE DIAGNOSIS FOR SYSTEMPFP:00000
Transmitter no DataNES000KA
MALFUNCTION CODE NO. 21, 22, 23, 24
1. CHECK CONTROL UNIT
Drive for several minutes. Check all tire pressures with CONSULT-II “DATA MONITOR”.
Are all tire pressures displayed 0 kPa?
YES >> GO TO 2.
NO >> GO TO 3.
2. CHECK TIRE PRESSURE RECEIVER CONNECTOR
1. Disconnect tire pressure receiver harness connector E74 (FR-LH), E75 (FR-RH), B482 (RR-RH), B115
(RR-LH).
2. Check terminals for damage or loose connection.
3. Reconnect harness connector.
OK or NG
OK >> Replace low tire pressure warning control unit. Refer to WT-40, "Low Tire Pressure Warning Con-
trol Unit" , then GO TO 3.
NG >> Repair or replace tire pressure receiver harness connector.
3. ID REGISTRATION
Perform ID registration of all transmitters.
Are there any tires that ID can not be registered to?
YES >> Replace transmitter of the tire, then GO TO 5.
NO >> GO TO 4.
4. VEHICLE DRIVING
Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping.
Check all tire pressures with CONSULT-II “DATA MONITOR” within 15 minutes after vehicle speed becomes
17 km/h (11 MPH).
Does
“DATA MONITOR ” display tire pressure as normal without any warning lamp?
YES >>INSPECTION END
NO >> GO TO 5.
5. ID REGISTRATION AND VEHICLE DRIVING
1. Perform ID registration of all transmitters.
2. Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for
10 minutes. Then check all tire pressures with CONSULT-II “DATA MONITOR” within 5 minutes.
Does
“DATA MONITOR” display tire pressure as normal without any warning lamp?
