ROAD WHEEL
Revision: 2005 July 2005 FX
ROAD WHEELPFP:40300
InspectionAES000OP
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 wheel 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):
Refer to WT-37, "
SERVICE DATA"
SFA975B
Radial runout = (A + B)/2
Lateral runout = (C + D)/2
Wheel runout : Refer to WT-37, "

TROUBLE DIAGNOSES
Revision: 2005 July 2005 FX
NOTE:
If more than one wheel transmitter is NOT activated, the warning lamp blinking patterns for those wheels will combine. (Example : one
blink/OFF/three blinks = Rear LH and Rear RH transmitters are not activated.)
CONSULT-II
CONSULT-II Main Function
In a diagnosis function (main function), there are “WORK SUPPORT”, “SELF-DIAGNOSTIC RESULTS”,
“DATA MONITOR”, “ACTIVE TEST”.
Low tire pres-
sure warning
lamp Warning lamp blinks
4 times Rear LH wheel

Diagnostic test mode Function Reference
WORK SUPPORT This mode enables a technician to adjust some devices faster and more
accurately by following the indications on CONSULT-II. WT-21, "
WORK SUP-
PORT MODE".
SELF-DIAGNOSTIC
RESULTS Self-diagnostic results can be read and erased quickly. WT-21, "
SELF-DIAG-
NOSTIC RESULTS

DATA MONITOR Input/Output data in the control unit can be read. WT-22, "
DATA MONITOR
MODE".
ACTIVE TEST Diagnostic Test Mode in with CONSULT-II drives some actuators apart
from the control unit (BCM) and also shifts some parameters in a specified
range. WT-22, "
