TIRE-CALIBRATE
TIRE SIZE
• During diagnosis, all of the communication lines connecting the compo-
nents are shown in yellow.
• If the system is OK, all of the communication lines connecting the compo-
nents will change to green, the screen will indicate "OK", and a tone will
sound.
• If there is a problem in the system, the faulty communication line will
change to red, the screen will indicate "NG", and a tone will sound.
• The indication on the screen will not change until the ignition switch is
cycled. After repairing the system, turn the ignition switch OFF to reset
the system, then return to the Diagnosis Menu screen, and run System
Links again.
• The "AUTO TUNING" is factory-set to "ON", and it should remain on. If
you find it has been turned OFF, turn it back ON.
• The "TIRE-CAL TUNING" can be used, but it is not recommended. The
AUTO TUNING function keeps the system in better tune.
• When you touch "TIRE CHANGE," the display will change to the TIRE
SIZE screen. This screen is rarely used because only the standard tire size
is listed.
• If the tire-cal factor has been reset, touching the tire size will return the tuning
value to the standard value.
